MCR01MZPF6041 - 6.04kΩ 1% 0402 Thick Film Chip Resistor | ROHM
The ROHM MCR01MZPF6041 is a 6.04 kOhm ±1% thick-film chip resistor in the 0402 (1005 metric) surface-mount package, rated at 0.063 W (1/16 W) and qualified to AEC-Q200 for automotive use. It is part of ROHM's MCR series of metal-glaze resistive-element chip resistors, a long-seller line spanning consumer, industrial, and automotive-grade designs. A chip resistor is a passive surface-mount component that provides a fixed resistance in a circuit using a thin- or thick-film resistive element screened onto an alumina ceramic substrate, terminated with nickel-barrier solderable end caps. Within the resistor taxonomy, chip resistors sit under fixed resistors, which themselves belong to the passive components family alongside capacitors and inductors. Thick-film parts like the MCR series trade a tighter tolerance and lower TCR for significantly lower cost compared with thin-film alternatives, making them the default choice for pull-up, pull-down, current-limiting, and general signal-conditioning applications. Key features of the MCR01MZPF6041 include ±1% resistance tolerance, ±100 ppm/°C temperature coefficient (TCR), 50 V maximum working voltage, -55 °C to +155 °C operating temperature range, and an automotive-grade AEC-Q200 qualification. The 0402 footprint (1.0 mm × 0.5 mm) enables ultra-compact PCB designs, particularly in mobile communication appliances and portable equipment. ROHM's metal-glaze resistive film provides long-term stability under thermal and humidity stress. The thick-film screen-printing process deposits a ruthenium-oxide-based resistive paste on a 96% alumina substrate, then fires it at high temperature to form a stable metal-glaze layer. Laser trimming is applied to dial the resistance to its final ±1% tolerance. The nickel-barrier solderable terminations accept standard reflow profiles (peak 260 °C) and provide robust solder-joint reliability under thermal cycling and mechanical shock, which is why the MCR series has remained a long-seller across consumer and industrial markets. Typical applications include general-purpose pull-up and pull-down resistors in microcontroller and logic I/O, RC time-constant networks, current-sense reference elements in low-power regulators, voltage-divider chains in sensor signal conditioning, and termination resistors on high-speed digital buses. AEC-Q200 qualification makes it directly usable in cabin ECU, infotainment, and body-control modules. When designing with this part, derate power at high ambient temperatures (the 0.063 W rating assumes 70 °C; at 155 °C the rating drops to zero). Keep solder-pad land patterns within the IPC-7351 nominal 0402 footprint to avoid tombstoning during reflow, and avoid placing the part directly under high-heat components. This page synthesizes cross-distributor pricing, AEC-Q200 qualification context, and design derating guidance not found in the manufacturer datasheet alone.
MCR100JZHF4641 - 4.64kΩ 1W 2512 AEC-Q200 Chip Resistor | ROHM
The ROHM MCR100JZHF4641 is a 4.64 kΩ thick-film chip resistor in a 2512 (6432 metric) surface-mount package with 1 W power rating and ±1% tolerance, qualified to the AEC-Q200 automotive standard. It belongs to the MCR100JZH high-power resistor series, which extends the standard MCR series up to 1 W ratings in the same chip footprint, supporting demanding automotive, industrial, and power-conversion designs. A chip resistor is a passive surface-mount component whose resistance value is set by a resistive thick-film layer (in this case, ruthenium-oxide dielectric, per the MCR100 family datasheet) printed between two wrap-around metal electrodes on an alumina substrate. Chip resistors form the base layer of every modern electronic circuit — biasing, current sensing, pull-up/pull-down, termination, voltage division, and filtering — and account for the majority of components on a typical PCB. The MCR100JZH family is positioned at the high-power end of this hierarchy (chip resistor -> thick-film chip resistor -> high-power chip resistor -> SMD passive), optimized for circuits where standard 0402/0805/1206 resistors would be thermally inadequate. Key features include a 4.64 kΩ resistance value, ±1% tolerance (versus the ±5% of the legacy MCR100 family), 1 W continuous power dissipation at 70 °C, a 200 V maximum working voltage, ±100 ppm/°C temperature coefficient, and an operating temperature range of −55 °C to +155 °C. The 2512 package provides a substantial thermal mass that lowers thermal resistance (theta_JA ≈ 25 °C/W on a 1 oz copper test board), enabling sustained 1 W operation without external heatsinking. The resistor is RoHS-compliant, lead-free, and AEC-Q200 qualified for automotive environments including engine-control ECUs, ADAS sensor biasing, and 12 V/24 V load-dump-protected rails. Architecturally, the MCR100JZH series uses a ruthenium-oxide thick-film paste fired onto a 96 % alumina substrate, with nickel-barrier/solder-coated wrap-around terminations for improved thermal cycling and solder-joint reliability. The series is built on the same basic platform as ROHM's general-purpose MCR100 family, but the JZH suffix denotes an extended-power rating and 1 % tolerance, allowing tighter tolerance without sacrificing power handling. Compared to thin-film resistors, thick-film offers superior pulse-withstand and surge capability, which is critical in automotive load-dump and jump-start scenarios. This part is well-suited for current-limiting on LED strings, gate-resistor networks in power MOSFET drivers, pull-up/pull-down in 24 V industrial logic, inrush-limiting on small DC-DC converter inputs, and biasing in automotive sensor signal chains. Its 2512 footprint also supports hand-rework and visual inspection during prototyping. When designing with this device, derate power linearly above 70 °C to zero at 155 °C, and follow standard 2512 land dimensions (roughly 6.4 mm × 3.2 mm pad with 0.3 mm × 0.3 mm solder mask sliver relief) for optimal solderability.
MCR10EZHMFX7151E - 7.15kΩ 0.125W 1% 0805 Thick Film Chip Resistor | ROHM
The Rohm Semiconductor MCR10EZHMFX7151E is an automotive-grade thick film chip resistor with a resistance value of 7.15 kOhms, 1% tolerance, and 0.125 W (1/8 W) power rating, housed in an industry-standard 0805 (2012 metric) surface-mount package. It belongs to the ROHM MCR series of metal-glaze thick film chip resistors that are AEC-Q200 qualified for automotive applications and widely used in industrial and consumer electronics. A thick film chip resistor is a passive component in which a metal-oxide resistive paste is screen-printed onto a ceramic alumina substrate, then fired at high temperature to form the resistive element. The thick film technology family sits within the broader resistor taxonomy of fixed resistors, which also includes thin film, wirewound, foil, and carbon composition types. Thick film is the workhorse technology for general-purpose surface-mount resistors because it offers a strong balance of cost, stability, and surge tolerance. The 0805 imperial code (2012 metric) places this part in the popular mid-size SMD family that handles 0.125 W comfortably with standard reflow profiles. Key features of the MCR10EZHMFX7151E include 7.15 kOhm resistance with +/-1% tolerance, a maximum working voltage and rated power per the ROHM MCR10 datasheet family, a temperature coefficient of resistance suited to general analog and digital signal-level applications, and AEC-Q200 automotive qualification that covers temperature cycling, humidity bias, and mechanical shock. The metal-glaze resistive element provides long-term stability and reliability required for industrial and automotive environments. The 0805 footprint supports standard pick-and-place assembly, and the part is supplied in tape-and-reel packaging compatible with automated SMT lines. Its 1% tolerance and 0.125 W rating make it broadly interchangeable with general-purpose 0805 chip resistors from other vendors, provided the user validates TCR, rated voltage, and pulse-load behavior. The automotive-grade qualification extends its usable envelope beyond consumer-grade resistors, making it suitable for under-hood, body electronics, and chassis domains. Typical applications include automotive body control modules, infotainment power rails, LED driver current-setting paths, industrial PLC analog signal conditioning, consumer white-goods control boards, and general-purpose pull-up or pull-down networks. The combination of AEC-Q200, 1% tolerance, and small 0805 footprint positions this part as a flexible drop-in for high-volume mixed-domain designs. When designing with this resistor, confirm the actual power dissipation against the application voltage and current using P = I^2R, and verify the working voltage does not exceed the datasheet maximum. For pulse or inrush conditions, consult the ROHM MCR series pulse-load chart before substituting. This page synthesizes current distributor pricing, AEC-Q200 qualification status, drop-in 0805 alternatives, and practical design notes not collected in a single location on the manufacturer datasheet, supporting faster component selection.
MCR10EZHUFX7501 - 7.5 kOhm 1% 1/8W 0805 Chip Resistor | Rohm
The Rohm Semiconductor MCR10EZHUFX7501 is a thick-film surface-mount chip resistor with a resistance value of 7.5 kOhms, a tolerance of +/-1%, a power rating of 0.125 W (1/8 W), and a temperature coefficient of +/-100 ppm/C, packaged in the industry-standard 0805 (2012 metric) case. A chip resistor (also called an SMD resistor or surface-mount resistor) is a passive electronic component that provides a precisely controlled resistance in a small, reflow-solderable package. Within the resistor taxonomy, this part belongs to the thick-film category, where a resistive ruthenium-oxide (RuO2) paste is screen-printed onto an alumina ceramic substrate and fired at high temperature. Thick-film resistors sit between wirewound and thin-film technologies in the precision hierarchy and dominate the consumer and industrial markets because they deliver adequate stability, low cost, and excellent solder-joint robustness. Key specifications of the MCR10EZHUFX7501 include a 7.5 kOhm nominal value (suffix 7501 in Rohm's coding), +/-1% resistance tolerance for precision pull-up, pull-down, and signal-conditioning tasks, +/-100 ppm/C TCR for moderate temperature stability, and an operating temperature window of -55C to +155C suitable for automotive under-hood and industrial environments. The 0805 footprint (2.0 x 1.25 mm) provides a balance between power handling and PCB density. Architecturally, the device uses Rohm's qualified MCR10 series platform, which targets AEC-Q200 automotive-grade reliability and provides a highly stable ruthenium-oxide resistive element with solder-plated nickel-barrier terminations that resist leaching during reflow. The series is engineered for low current noise and minimal drift across humidity and thermal-cycling stresses, making it suitable for long-life field applications. Typical applications include general-purpose pull-up and pull-down networks in microcontrollers and logic interfaces, current-limiting and feedback paths in switching power supplies, ADC/DAC reference-divider ladders, and bias networks in automotive ECU modules. The AEC-Q200 qualification on the broader MCR10 series also makes it well suited for body-electronics and chassis-control ECUs. When designing with this part, derate power aggressively at elevated ambient temperatures - the 0.125 W rating assumes 70C or below. Use generous land patterns per IPC-7351 to improve solder-joint reliability under thermal cycling. This page synthesizes distributor pricing, MCR10-series alternatives, and practical design guidance not aggregated on any single manufacturer or distributor page.
MCR10EZPF1052 - 10.5kΩ ±1% 0.125W 0805 Thick Film Resistor | ROHM
The ROHM MCR10EZPF1052 is a 10.5 kΩ thick-film chip resistor in the industry-standard 0805 (2012 metric) footprint, rated at 0.125 W (1/8 W) with ±1% resistance tolerance and ±100 ppm/°C temperature coefficient. Housed in a surface-mount 0805 case, this part belongs to ROHM's long-running MCR series of AEC-Q200-qualified thick-film rectangular chip resistors, making it suitable for consumer, industrial, and automotive electronics designs. A thick-film chip resistor is a passive component in which a metal-glaze resistive paste is screen-printed onto a ceramic alumina substrate and fired at high temperature, then trimmed to the target value with a laser or abrasive cut. The MCR series sits within the broader surface-mount resistor family, which includes thin-film, foil, and wire-wound variants; thick-film technology offers the best cost-to-performance balance for general-purpose use, while thin-film is reserved for higher-precision or low-noise applications. As a discrete passive, the chip resistor is one of the most fundamental building blocks in any electronic circuit, used for current limiting, voltage division, pull-up/pull-down, and termination. Key features of the MCR10EZPF1052 include a 10.5 kΩ resistance value encoded in the part number (1052 = 105 × 10² = 10500 Ω), ±1% tolerance for accurate divider and bias networks, ±100 ppm/°C TCR for stable operation across automotive temperature swings, and AEC-Q200 qualification that validates reliability under automotive stress profiles. The 0805 footprint measures 2.0 × 1.25 mm and supports automated pick-and-place assembly with paper-tape packaging at 5,000-piece reels. Maximum working voltage is 150 V and overload voltage is 300 V per the MCR series ratings. Typical applications span automotive ECUs, sensor signal conditioning, industrial PLC I/O modules, consumer appliance control boards, and any general-purpose pull-up or current-sense network. The combination of 1% tolerance, 100 ppm/°C TCR, and automotive-grade reliability makes the MCR10EZPF1052 a strong general-purpose choice when precision matching of multiple resistors is not required. Where tighter ratio tolerance is needed (e.g., precision amplifiers, current sensing), designers should consider thin-film alternatives; otherwise, the MCR series offers an excellent cost-down path.
MCR18ERTF5901 - 5.9 kOhm 1% 1/4W 1206 AEC-Q200 Resistor | ROHM
The ROHM Semiconductor MCR18ERTF5901 is a 5.9 kOhm ±1% tolerance thick-film chip resistor rated at 0.25 W (1/4 W) in a 1206 (3216 metric) surface-mount package, qualified to the AEC-Q200 automotive stress standard. Key parameters are 5.9 kOhm resistance, ±100 ppm/°C temperature coefficient, and 1206 footprint with wraparound terminations. A chip resistor is a passive SMD component whose resistance is set by a thick- or thin-film layer deposited on an alumina (Al2O3) ceramic substrate. Thick-film resistors use a ruthenium-oxide (RuO2) or silver-palladium paste screen-printed onto the substrate and fired, then laser- or abrasive-trimmed to value; they sit within the taxonomy resistor → fixed resistor → surface-mount resistor → chip resistor. The 1206 case (3.2 × 1.6 mm) is the second-most-popular SMD size after 0805 and offers a useful compromise between power handling, parasitic reactance, and ease of hand rework. Key features of the MCR18ERTF5901 include ±1% resistance tolerance, ±100 ppm/°C TCR (suitable for general-purpose analog and digital circuits where drift over -55 °C to +155 °C is acceptable), anti-sulfur construction typical of the MCR-series 'E' designation, and a -55 °C to +155 °C operating range. The wraparound Ni/Sn solder terminations are compatible with lead-free reflow profiles up to 260 °C peak per JEDEC J-STD-020. Technically the part belongs to ROHM's MCR18 (1206 1/4 W) family. The 'ER' suffix denotes ±1% / 100 ppm/°C and the trailing 'F' identifies Pb-free packaging, while 'T' indicates Tape & Reel. The '5901' is the resistance code in Rohm's 4-digit EIA-96-style system (590 × 10^1 = 5900 Ω). Junction-to-ambient thermal resistance is approximately 250 °C/W on a standard 1-oz FR-4 test board, so derating begins around 70 °C ambient. Typical applications include general-purpose pull-up / pull-down networks, LED current-setting in 10–20 mA ranges, op-amp gain-setting, RC timing, and automotive ECU, body, and chassis modules where AEC-Q200 qualification is mandated. In all cases it is used as a fixed, stable bias or reference element. When designing with this part, confirm that worst-case dissipation stays below the derated 1/4 W rating across the full operating temperature range and keep solder-joint geometry within JEDEC land-pattern recommendations to preserve the AEC-Q200 reliability margin. This page synthesizes distributor pricing, AEC-Q200 alternative mapping, and practical design notes not found in the manufacturer datasheet alone.
MF72-010D7 - 10Ω 1A Power NTC Thermistor Inrush Limiter | Cantherm
The Cantherm MF72-010D7 is a power NTC (negative temperature coefficient) thermistor designed as an inrush current limiter (ICL), rated 10 Ω at 25 °C with ±20% tolerance, 1 A steady-state maximum current, and a 9.0 mm disc diameter. It is supplied in a radial-lead bulk package with 5.00 mm lead spacing and dissipates initial turn-on surges through its self-heating resistance drop from 10 Ω cold to roughly 0.616 Ω at full rated current. An NTC thermistor is a semiconductor passive component whose resistance decreases as temperature rises. In power-electronics inrush protection, an NTC ICL is placed in series with the input rail; its high cold resistance suppresses the capacitive charge spike at switch-on, then self-heats to a low steady-state resistance that minimizes continuous conduction loss. The MF72 series belongs to the broader ICL family, which sits within circuit protection components and bridges passive thermistor technology and active surge-suppression schemes. Key features include a 10 Ω cold resistance (R25), 0.616 Ω hot resistance at the 1 A steady-state current point, ±20% R25 tolerance, 1 A maximum continuous current, 9.0 mm disc diameter, 5.00 mm radial lead spacing, and bulk packaging optimized for through-hole wave or hand soldering. The disc geometry maximizes surface area for rapid thermal dissipation once the inrush event ends, restoring low-loss operation within seconds. Technically, the MF72-010D7 uses a transition-metal-oxide ceramic body whose exponential resistance-vs-temperature curve follows the beta-value model. Above the device's dissipation constant, the resistance collapses sharply, which is precisely why it limits inrush but does not regulate steady-state current. Designers should evaluate the cold-resistance energy (i²t) budget against the upstream fuse and bulk capacitor size to ensure reliable coordination. Typical applications include switch-mode power supply (SMPS) input stages, AC-DC converters, motor soft-start circuits, lighting ballasts, and any capacitive-load power entry where a turn-on surge would otherwise trip breakers or stress rectifiers. The 10 Ω cold value suits supplies in the 5 W to 30 W class. A critical design consideration is thermistor re-cooling time: after a heavy inrush the MF72-010D7 remains hot and low-resistance, so a second power-up within seconds receives little protection. A timed relay bypass or a parallel PPTC is sometimes added when the application demands rapid restart capability. This page synthesizes distributor pricing, drop-in alternatives from the MF72 series and competing NTC ICL families, and practical design notes not found on the manufacturer datasheet alone, giving the engineer a one-stop reference for sourcing and qualifying the MF72-010D7.
MFR-25FRF52-1K5 - 1.5 kOhm 1% 0.25W Axial Metal Film Resistor | YAGEO
The YAGEO MFR-25FRF52-1K5 is a 1.5 kOhm ±1% tolerance, 0.25W (1/4W) axial through-hole metal film resistor in the MFR Series, qualified to ±100 ppm/°C temperature coefficient (TCR) and AEC-Q200 automotive standards. It is supplied in tape-and-reel packaging (T/R) and is engineered for general-purpose analog and digital circuits that demand stable resistance over temperature, time, and humidity. A metal film resistor is a passive component whose resistive element is a metallic film (often nickel-chromium) sputtered or vacuum-deposited onto a high-purity ceramic substrate, then laser- or helix-trimmed to a precise value. Within the broader passive-component taxonomy, metal film resistors sit between carbon film (cheaper, noisier, worse TCR) and wirewound (high power, low resistance) parts, and are the standard choice for low-noise precision circuits. The MFR Series is YAGEO's workhorse general-purpose metal film line, and the 25-size code denotes a 0.25W rated axial body. Key features include a resistance of 1.5 kOhm at ±1% tolerance, a maximum working voltage of 250V, an operating temperature range of -55 °C to +155 °C, and an axial-lead form suited to automatic insertion and wave soldering. The 100 ppm/°C TCR delivers an end-of-life resistance shift on the order of 0.25% over a 25 °C temperature excursion at 1.5 kOhm, supporting precision bias networks, op-amp gain stages, and ADC reference ladders where drift would degrade accuracy. Technically, the MFR Series uses a homogeneous metal film with welded terminations and a flame-retardant epoxy coating. The combination of tight tolerance, low noise, and AEC-Q200 automotive qualification distinguishes it from generic carbon-film 1/4W parts, which typically show 5% tolerance and 350-500 ppm/°C TCR. Typical applications include op-amp feedback networks, current-sense biasing with high-side or low-side amplifiers, MCU pull-up/pull-down resistors, audio pre-amp gain stages, ADC input dividers, and general signal-conditioning networks. The AEC-Q200 qualification extends its use into automotive body electronics, HVAC controllers, and infotainment modules. When designing with this part, derate power at high ambient temperatures: above 70 °C, permissible dissipation drops linearly to zero at 155 °C. Keep lead-bend stress below 1 kg to avoid cracking the ceramic body, and maintain a minimum lead clearance of 5 mm between the body and the PCB for proper flux wash.
RC0603FR-0710KL - 10kOhm 1% 0.1W 0603 Chip Resistor | YAGEO
The YAGEO RC0603FR-0710KL is a 10 kOhm surface-mount thick film chip resistor with a resistance tolerance of ±1%, a power rating of 0.1 W (1/10 W), and a 0603 (1608 Metric) package. It belongs to YAGEO's RC general-purpose series, which uses lead-free terminations and a moisture-resistant thick film construction. A chip resistor is the most fundamental passive component in electronics: a fixed resistor that limits current, sets gain in amplifier networks, forms voltage dividers, and provides pull-up/pull-down biasing. Chip resistors sit within the broader hierarchy of passive components -> resistors -> fixed resistors -> surface-mount thick film resistors. The 0603 imperial size (1.6 mm x 0.8 mm, hence 1608 Metric) is the workhorse SMD package, balancing density, pick-and-place handling, and power capability. Key features of the RC0603FR-0710KL include its precise ±1% tolerance, a temperature coefficient of ±100 ppm/C, and a moisture-resistant protective overcoat suitable for standard reflow assembly. The thick film resistive element is laser-trimmed for accuracy, and the lead-free nickel-plated terminations ensure excellent solderability and compatibility with lead-free (RoHS) soldering profiles. Technically, the thick film process deposits a ruthenium-oxide-based resistive paste on a ceramic alumina substrate, which is then laser trimmed to the target resistance. The ±100 ppm/C TCR keeps value drift to roughly 0.1% over a 100 C temperature swing, so in most general-purpose circuits the 1% tolerance dominates overall accuracy. The 0.1 W rating applies with proper PCB land patterns per the manufacturer specification sheet; derating is required at elevated ambient temperatures. Typical applications include general purpose voltage dividers, pull-up/pull-down networks for digital I/O and I2C/SPI buses, current limiting for LEDs, feedback networks around DC-DC converters and LDO regulators, and gain-setting resistors around operational amplifiers where 1% accuracy is sufficient. Design tip: for circuits needing better than 1% accuracy or higher power, move to YAGEO's 0.5% (D tolerance) RC0603 variants or a larger 0805 package; for automotive qualification, choose the AC0603FR-0710KL AEC-Q200-style automotive variant with the same footprint. This page synthesizes distributor pricing, drop-in cross-brand alternatives, application guidance, and design notes not found in a single manufacturer datasheet, helping engineers and buyers source the RC0603FR-0710KL with confidence.
RC0805FR-0710KL - 10kOhm 1% 0.125W 0805 Chip Resistor | YAGEO
The YAGEO RC0805FR-0710KL is a 10 kOhm thick film surface-mount chip resistor with +/-1% resistance tolerance, 0.125 W (1/8 W) power rating, and +/-100 ppm/C temperature coefficient, packaged in the industry-standard 0805 (2012 metric) case size with moisture-resistant construction. A chip resistor is the most fundamental passive component in electronics: a fixed-resistance element that limits current, divides voltage, sets bias points, and terminates transmission lines. Within the component hierarchy, it belongs to the resistor family under passive components, and the 0805 surface-mount format is one of the most widely consumed packages in the global electronics industry, occupying the middle ground between the smaller 0603 (typically 100 mW) and the larger 1206 (typically 250 mW) sizes. Compared to 0603, the 0805 footprint provides 25% more rated power dissipation, a meaningful upgrade when thermal margin matters. Key features of the RC0805FR-0710KL include a maximum working voltage of 150 V, high reliability thick film element on an alumina substrate, lead-free pure-tin plated terminations, and moisture resistance suitable for standard reflow soldering processes. The F code in the MPN denotes the +/-1% tolerance grade, and the L suffix identifies the tape-and-reel (7-inch reel) packaging format for automated pick-and-place assembly. Technically, the resistive element is a ruthenium-oxide-based thick film paste screen-printed onto a 96% alumina ceramic substrate and laser-trimmed to the 10 kOhm nominal value. YAGEO's thick film process delivers tight tolerance distribution and stable TCR behavior across the -55C to +155C operating range typical of the RC series, with a rated ambient temperature derating above 70C per the manufacturer datasheet. Typical applications include general-purpose pull-up/pull-down networks, voltage dividers in consumer electronics, signal conditioning in industrial control boards, gain-setting resistors around operational amplifiers, and current limiting for LEDs and logic inputs. The 1% tolerance supports precision divider ratios without the cost of thin film parts. Design consideration: at the full 0.125 W rating, plan PCB copper area for heat dissipation and consider derating to 50-70% of rated power in dense assemblies or high ambient temperatures to maximize long-term reliability and drift performance. This page synthesizes distributor pricing, drop-in alternatives from Vishay and Bourns, and practical design notes not found in the manufacturer datasheet, providing engineering context for sourcing decisions.
RNR55E9092FSRSL65 - 90.9kOhm 0.125W Mil Metal Film Resistor | Vishay
The Vishay Dale RNR55E9092FSRSL65 is a precision 90.9 kOhm metal film through-hole resistor with a ±1% tolerance and a 0.125 W (1/8 W) power rating, supplied in an axial-leaded, flame-retardant, moisture-resistant package designed for military and high-reliability applications. A fixed through-hole resistor is a passive two-terminal component that provides a defined resistance for current limiting, voltage division, gain setting, and pull-up or pull-down functions in a circuit. In the passive-component hierarchy, the metal film resistor sits above generic carbon-film types in precision and stability, and the RNR55 family belongs to the military-grade precision resistor class established under the MIL-PRF-55182 style heritage, where controlled temperature coefficient, moisture resistance, and flame-retardant coating are mandatory attributes. Key features of the RNR55E9092FSRSL65 include the tight 90.9 kOhm E96-series value, a ±1% tolerance for accurate analog bias networks, a 0.125 W power rating suited to signal-level circuits, an axial through-hole body that supports reliable hand and wave soldering, and a metal film resistive element with flame-retardant, moisture-resistant coating per the military specification family. The RSL65 suffix in the part number encodes lead finish and established-reliability feature coding used by Vishay for space and defense procurement. Technically, the metal film element is deposited on a ceramic core and laser-trimmed to the nominal 90.9 kOhm value, giving the part lower excess noise and better long-term stability than carbon composition types. The military-grade construction emphasizes environmental robustness: conformal flame-retardant coating and moisture-resistant encapsulation protect the element in humid, thermally stressed environments typical of defense, avionics, and industrial instrumentation platforms. Typical applications include high-reliability analog signal chains in avionics and defense electronics, precision voltage dividers and reference networks in test and measurement equipment, bias networks in industrial instrumentation, and legacy military program sustainment where MIL-style metal film resistors are specified by drawing. A key design consideration is power derating: at 0.125 W rating, designers must derate significantly at elevated ambient temperatures per the manufacturer specification, and lead spacing must match the axial body length to avoid mechanical stress on the solder joints. This page synthesizes distributor pricing, drop-in same-family alternatives, and practical military-resistor design notes not consolidated in the manufacturer datasheet alone.
RT0402CRD079R09L - 9.09 Ohm Thin Film Chip Resistor | YAGEO
The YAGEO RT0402CRD079R09L is a precision thin-film chip resistor with a nominal resistance of 9.09 Ohms and a tolerance of plus-or-minus 0.25 percent, rated for 0.063 W (1/16 W) continuous power dissipation. It is supplied in an industry-standard 0402 (1005 metric) surface-mount package, making it compatible with high-density PCB assemblies where low noise and tight tolerance are required. A thin-film resistor is a passive component whose resistive element is a sputtered metal-alloy film, typically nickel-chromium, deposited on a ceramic substrate. Because the film is patterned by photolithography rather than by composition variation as in thick-film resistors, thin-film parts deliver tighter absolute tolerance, lower temperature coefficient of resistance (TCR), and markedly lower current noise. Within the broader taxonomy, this device is a chip resistor -> surface-mount resistor -> passive component -> electronic component, and YAGEO's RT series is the company's precision thin-film line. Key features include the plus-or-minus 0.25 percent tolerance, a 0402 footprint measuring 1.0 mm by 0.5 mm, and the moisture-resistant thin-film construction typical of the YAGEO RT family. The series is qualified for reflow soldering at peak temperatures up to 260 degrees Celsius and is RoHS compliant. Although YAGEO's general thin-film rating for the 0402 case size is 1/16 W (0.063 W) at 70 degrees Celsius, designers must derate to zero power at the upper operating temperature of 155 degrees Celsius per the RT datasheet. The RT0402CRD079R09L uses the same NiCr film technology as other parts in the RT family, which YAGEO documents at TCR values as low as plus-or-minus 25 ppm per degree Celsius and very low current noise of less than minus 35 dB. The 9.09 Ohm value is part of the standard E96 resistance series, allowing tight tolerance and low drift in precision analog circuits such as feedback networks, current-sense shunts, and reference-setting dividers. Typical applications include precision analog front-ends, sensor-signal conditioning, current-sense paths for low-voltage rails, precision gain-setting resistor pairs in instrumentation amplifiers, and test-and-measurement reference dividers. The 0.1 percent-class stability over time (per the RT family long-term drift data) also makes it suitable for load-cell and weighing-scale analogue signal chains. When designing with this part, observe the manufacturer's derating curve by reducing applied power as the ambient temperature approaches 155 degrees Celsius, and select adjacent series values such as 9.10 Ohm or 9.05 Ohm if the E96 9.09 Ohm nominal is unavailable across preferred suppliers. Use a copper pad geometry that matches the 0402 land-pattern recommendation to avoid tombstoning during reflow. This page synthesises distributor availability, drop-in alternatives, and the manufacturer's derating guidance into a single engineer-focused reference that complements the official datasheet.
RT0805WRD072KL - 2kΩ 0.05% 1/8W Thin Film Chip Resistor | YAGEO
The YAGEO RT0805WRD072KL is a 2 kΩ thin-film chip resistor with ±0.05% tolerance and 1/8 W (0.125 W) power dissipation, packaged in the industry-standard 0805 (2012 metric) surface-mount footprint measuring 2.0 x 1.25 mm. As part of YAGEO's RT-series high-precision thin-film resistor family, this part is engineered for circuits that demand tight resistance tolerance, low temperature coefficient of resistance (TCR), and excellent long-term stability over a wide operating temperature range. A chip resistor is a passive two-terminal component that provides a defined value of electrical resistance in a surface-mount package. The 0805 imperial code designates a 2.0 mm x 1.25 mm land pattern, while the "2012 metric" notation refers to the same dimensions in metric (2.0 mm x 1.25 mm). Within the broader taxonomy, this part is a thin-film chip resistor, a sub-category of fixed resistors, which themselves belong to the passive component family used in nearly every electronic circuit for current limiting, voltage division, biasing, and signal conditioning. Key features include ±0.05% resistance tolerance (significantly tighter than standard 1% or 5% thick-film chip resistors), 25 ppm/°C nominal TCR for stable performance across temperature, 1/8 W rated power at 70°C, and compliance with lead-free reflow profiles up to 260°C peak. The thin-film nichrome resistive element sputtered onto a ceramic alumina substrate delivers lower noise (-40 dB typical) and better high-frequency characteristics than thick-film equivalents. The end terminations are wrap-around Ni-barrier with matte-tin plating for excellent solderability and leach resistance during multiple reflow cycles. Technically, the thin-film sputtering process produces a uniform resistive layer whose cross-section and composition can be laser-trimmed to within ±0.05% of the target value. This precision enables the resistor to be used as a reference element in measurement-grade signal chains. The 0805 package supports standard pick-and-place assembly, and the part is qualified against industry reliability standards including AEC-Q200 (for the qualified grade). Typical applications include precision analog front-ends, instrumentation amplifier gain-setting networks, precision voltage dividers in ADCs and DACs, bridge excitation circuits in load cells and pressure sensors, test and measurement equipment, and medical instrumentation. Designers also select this tolerance class for feedback networks in switching regulators where resistor mismatch directly affects output accuracy. When designing with the RT0805WRD072KL, observe derating guidelines above 70°C ambient: power dissipation must be linearly reduced to zero at 155°C. For precision divider networks, pair two resistors of the same lot to minimize ratio drift. This page consolidates distributor pricing, drop-in alternatives, and application engineering notes beyond what the YAGEO datasheet alone provides.
SCMM2512S2-0M80F - 0.8 mOhm 2W Current Sense Resistor | Cyntec
The Cyntec SCMM2512S2-0M80F is a 0.8 milliohm (±1%), 2 W surface-mount current-sense chip resistor in a 2512 (6332 metric) metal-film package. It is engineered for current-sensing applications that require a low-resistance shunt with high pulse-withstanding capability, low thermal EMF, and stable performance across temperature. The 2512 footprint measures approximately 6.35 mm × 3.20 mm, and the part ships in tape-and-reel packaging for high-volume SMT assembly. According to the Cyntec SCMM2512S2 datasheet, the SCMM2512S2 family is offered lead-free and halogen-free. A current-sense resistor is a low-ohm precision resistor placed in series with a load so that the voltage drop across it is proportional to the load current. This voltage drop is then amplified by an op-amp, current-sense amplifier, or ADC channel to implement closed-loop control, telemetry, or protection. Current-sense resistors sit in the signal-chain hierarchy as: current-sense resistor -> passive component -> resistor -> chip resistor -> SMD resistor. They are preferred over Hall-effect sensors and current transformers when accuracy, bandwidth, and cost are the primary design drivers. Key features of the SCMM2512S2-0M80F include 0.8 milliohm (1% tolerance), 2 W continuous power rating, a metal-film resistive element, and pulse-withstanding construction. Its 2512 footprint provides a large solder-pad area for heat spreading, while the low resistance value minimizes both I2R conduction loss and the insertion voltage burden in the load path. Compared with sense resistors above 5 milliohm, a 0.8 milliohm part reduces wasted power by more than 6x at the same load current. From a technical perspective, the SCMM2512S2 series uses Cyntec's metal-film process on a ceramic substrate, providing a typical TCR of ±100 ppm/°C or better and an operating temperature range that supports automotive underhood and industrial environments. The low-ohm metallization is tuned to give low thermal EMF against copper pads, which keeps measurement error below 1% in typical 4-wire Kelvin layouts. Typical applications for the SCMM2512S2-0M80F include DC-DC converter output current feedback, battery-pack charge/discharge monitoring in BMS designs, motor-control current sensing in industrial drives, USB-PD and high-current Type-C ports, server and telecom 12 V/48 V rail monitoring, and automotive ECU power monitoring. Designers choose it when they need a low-ohm, high-power, pulse-tolerant shunt in a standardized 2512 land pattern. When laying out this part, use a Kelvin (4-wire) connection to the sense pads so that the high-current path and the voltage-sensing path are physically separated. Place the sense traces close together and away from switching nodes to avoid capacitive coupling; add a small RC filter at the amplifier input to reject high-frequency noise. Reserve at least 1 oz copper on both top and inner layers under the pads to keep the resistor temperature rise within the 2 W rating. This page consolidates distributor pricing for the SCMM2512S2-0M80F, drop-in and parametric equivalents, and practical layout notes that are not reproduced in the Cyntec datasheet itself.
SFR2500002550FR500 - 255Ω 0.4W 1% Metal Film Resistor | Vishay
The Vishay SFR2500002550FR500 is a 255 Ω through-hole axial metal film resistor from the SFR25 series, rated for 0.4 W power dissipation with a ±1% tolerance and ±100 ppm/°C temperature coefficient. Housed in a compact 0207-size axial leaded package, this part is supplied on Tape & Reel (TR) with 5000 pieces per reel and is drop-in compatible with the historical SFR55 designation from BC Components. A metal film resistor is a passive electronic component whose resistive element is a thin homogeneous layer of metal alloy deposited on a high-grade ceramic substrate, then laser-trimmed to a precise resistance value. Metal film technology sits above carbon film in the resistor taxonomy (carbon film -> metal oxide film -> metal film -> precision wirewound), offering superior noise performance, tighter tolerance, and lower temperature coefficient - making metal film the default choice for general-purpose precision analog and signal-conditioning circuitry where carbon film drift or noise would be unacceptable. Key features include a low-noise specification of maximum 1.5 µV/V for resistances above 1 MΩ, a long-term stability rating typical of the SFR25 family, lead-free construction compliant with current RoHS directives, and stable operation across industrial temperature ranges. The 0207 axial form factor provides mechanical robustness for through-hole assembly while remaining compact enough for dense PCB layouts. Technically, the SFR25 construction uses a vacuum-deposited metal alloy film on a ceramic body, followed by a helical cut that precisely sets the resistance value. The end caps are force-fit, and the leads are tin-plated copperweld for reliable solderability. This process yields the tight ±1% tolerance directly out of the box, eliminating the need for hand-selection in most precision designs. Typical applications include precision analog signal conditioning, instrumentation amplifier gain-setting, ADC/DAC reference networks, general-purpose pull-up/pull-down resistors in mixed-signal designs, and audio preamplifier circuitry where low noise is critical. The 255 Ω value is commonly used in RF termination networks, current-sense shunt references, and 4-20 mA loop termination. When designing with this part, observe derating guidelines - at 70 °C ambient the rated 0.4 W should be reduced to keep the hot-spot temperature below the 155 °C maximum. For high-impedance circuits, the low noise specification ensures negligible self-generated voltage across the resistor. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in any single manufacturer datasheet.
TFCR1206-4W-K-38R8FT - 38.8Ω ±1% 1/4W Thin Film Resistor | Venkel
The Venkel TFCR1206-4W-K-38R8FT is a 38.8 ohm precision thin-film chip resistor in the industry-standard 1206 (3216 metric) surface-mount package, offering ±1% resistance tolerance, ±100 ppm/°C temperature coefficient of resistance (TCR), and 0.25 W (1/4 W) power dissipation. It belongs to Venkel's TFCR series of thin-film chip resistors, which are designed for high-precision, high-stability applications where standard thick-film chip resistors fall short on noise, tolerance, and TCR performance. A thin-film resistor is a passive component whose resistive element is deposited as a very thin layer (typically nickel-chromium or tantalum nitride) onto a ceramic substrate, then laser- or photolithographically trimmed to the target value. This construction yields tighter absolute tolerance, lower noise (often an order of magnitude below thick-film), lower voltage coefficient of resistance, and superior long-term stability compared to thick-film chip resistors. Within the broader electronic component taxonomy, thin-film chip resistors belong to the passive components family and are widely used as reference, sense, feedback, and gain-setting elements in analog signal paths. Key features of the TFCR1206-4W-K-38R8FT include a 38.8 Ω resistance value in E96 series notation, ±1% initial tolerance (the "K" tolerance code in Venkel's naming convention), ±100 ppm/°C TCR (the "4W" code), 0.25 W rated power at 70 °C, and an operating temperature range of -55 °C to +155 °C. The 1206 footprint measures 3.20 mm × 1.60 mm and is fully compatible with standard 1206 land patterns used across the industry, allowing drop-in substitution on virtually any 1206 pad layout. The part is supplied in tape-and-reel packaging for automated pick-and-place assembly. Thin-film chip resistors of this type typically employ a sputtered NiCr alloy film on an alumina (Al₂O₃) substrate with solder-plated nickel-barrier terminations, and are passivated to protect the resistive element from environmental contamination. The combination of low TCR, tight tolerance, and low noise makes the TFCR1206-4W-K-38R8FT particularly suitable for precision analog front-ends, instrumentation amplifiers, sensor signal conditioning, and reference-voltage dividers where ratio-match stability across the operating temperature range is critical. Typical applications include precision current-sense shunts in low-side sensing topologies, gain-setting resistors in op-amp circuits, feedback networks in DC-DC converters, precision voltage dividers in ADC reference ladders, and filter networks in audio and instrumentation signal chains. Designers also use the part in medical, test-and-measurement, and industrial automation equipment where long-term drift must be minimized. When designing with this part, derate power above 70 °C per the standard thin-film resistor power-derating curve (linearly to zero at 155 °C), and verify the pad geometry to the manufacturer's recommended reflow footprint. For circuits requiring tighter than ±1% tolerance, consider Venkel's TFCR1206-4W-C (±0.25%) or TFCR1206-4W-E (±0.1%) variants in the same 1206 footprint. This page synthesizes Venkel distributor pricing, drop-in same-package alternatives (TFCR1206-4W-C-38R8FT, TFCR1206-4W-E-38R8BT), and packaging information not consolidated on a single OEM product page.
TNPW060383K5BEEA - 83.5 kOhm 0.1% Thin Film Resistor | Vishay
The Vishay Dale TNPW060383K5BEEA is a precision thin-film chip resistor rated at 83.5 kOhms with ±0.1% tolerance, 0.21 W power dissipation (1/8 W rating per some distributor listings), 75 V maximum working voltage, and 25 ppm/°C temperature coefficient, housed in an industry-standard 0603 (1608 Metric) surface-mount footprint. A thin-film chip resistor is a passive component whose resistive element is a sputtered metal-alloy film (nickel-raseless or NiCr-based) deposited on a ceramic alumina substrate. Compared to thick-film chip resistors, thin-film technology offers tighter absolute tolerance (often ±0.1% or better), lower temperature coefficient of resistance (TCR, often 25 ppm/°C or 5 ppm/°C for premium grades), and markedly lower parasitic inductance and noise. These attributes place thin-film resistors in the precision-resistor category used where thick-film ±1% or ±5% parts would introduce unacceptable error. Within the resistor taxonomy, this part belongs to the family thin-film resistor -> chip resistor -> SMD resistor -> passive component. Key specifications include 83.5 kOhm resistance, ±0.1% tolerance, 25 ppm/°C TCR, 0.21 W power rating (Vishay datasheet value; the 1/10 W figure from Mouser reflects a more conservative EIA-rated figure), anti-sulfur construction per Vishay's automotive-grade qualification, AEC-Q200 automotive qualification, and lead-free (Pb-free) reflow-compatible terminations. The part is qualified against JEDEC JESD97 paragraph 3.5 for Pb content below 0.1% by weight in the termination material. The 0603 (1608 metric) case size measures 1.55 mm × 0.85 mm × 0.45 mm and is one of the most widely-used SMD footprints. Vishay's TNPW e3 series combines this standard footprint with thin-film stability, enabling the part to be specified in precision analog signal paths, automotive ECUs, and instrumentation front-ends without altering board layout versus conventional thick-film 0603 resistors. Typical applications include precision voltage dividers, gain-setting resistors in op-amp circuits, current-sense reference networks, ADC/DAC reference ladders, automotive sensor signal conditioning, instrumentation amplifier gain networks, and bridge-circuit completion resistors. The AEC-Q200 qualification makes the device directly usable in under-hood and chassis automotive electronics. A key design consideration is that the 0.1% tolerance and 25 ppm/°C TCR deliver precision only when the resistor is operated well below its rated power; power derating above 70°C ambient is required to keep self-heating drift within the published TCR envelope. For best stability, maintain dissipation below ~50% of rated power in precision divider positions. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
TNPW06038K06BEEA - 8.06 kOhm 0.1% 25ppm Thin Film Resistor | Vishay Dale
The Vishay Dale TNPW06038K06BEEA is an 8.06 kOhm precision thin film chip resistor in an 0603 (1608 metric) surface-mount package with 0.1% tolerance and ±25 ppm/°C temperature coefficient. It is rated for 0.21 W (DigiKey listing) or 0.125 W (1/8 W per the manufacturer datasheet family) of continuous dissipation and supports an operating temperature range of -55°C to +155°C. The part carries Vishay's automotive-grade TNPW e3 series designation, meaning it is qualified to AEC-Q200, anti-sulfur, and moisture-resistant. Thin film chip resistors are a subclass of surface-mount resistor technology where a precisely deposited nickel-chromium or tantalum-nitride film on a ceramic alumina substrate defines the resistance value. Compared to thick film chip resistors (the lower-cost alternative used in consumer electronics), thin film parts achieve roughly an order of magnitude better tolerance and temperature coefficient, at the cost of slightly higher unit price. They sit hierarchically inside the broader resistor taxonomy of passive components, and within Vishay's portfolio the TNPW e3 family represents the high-stability, automotive-qualified tier above the standard CRCW thick film line. Key features of the TNPW06038K06BEEA include ±0.1% initial tolerance (1000 ppm accuracy), ±25 ppm/°C TCR for stable behavior across automotive and industrial temperature swings, anti-sulfur construction that survives ASTM B809 sulfide environments, and moisture-resistant terminations that withstand lead-free reflow profiles. The 0603 footprint is the second smallest in the imperial chip-resistor line (0402, 0603, 0805, 1206...) and is one of the most universally stocked resistor footprints in the industry. Typical applications include precision analog signal conditioning, automotive ECU sensor biasing, instrumentation amplifier gain setting, and reference current-limiting networks where the TCR and tolerance directly affect system accuracy. The wide operating temperature window and AEC-Q200 qualification also make it suitable for under-hood automotive modules and industrial process control. When designing with this part, derate power according to the Vishay TNPW derating curve - the 0.125 W rating assumes a 70°C ambient with linear derating to zero at 155°C. Place the part on a land pattern compliant with IPC-7351 nominal 0603 to ensure solder joint reliability under thermal cycling.

TR - Ambiguous Electronic Component Designator | XAIPART
TR is not an unambiguous electronic component part number in the supplied source data. Instead, the verified search results associate the two-character designation with multiple unrelated entities: a YAGEO thick-film resistor series code, Vishay high-voltage thick-film planar resistors, a suffix used on unrelated semiconductor orderable codes, ANSI post-type insulator references, and several non-electrical uses. Because no manufacturer, package, electrical ratings, pinout, or manufacturer-specific orderable suffix is established, this identifier cannot be assigned one safe component identity or used for drop-in replacement without additional context. An electronic resistor is a passive two-terminal component that limits current and produces a voltage proportional to that current. The identified Vishay TR material appears under thick-film planar resistors for through-hole, high-voltage applications, while the YAGEO search result identifies TR as a thick-film resistor-series code. Those results establish a possible resistor context, but they do not provide a resistance value, power rating, tolerance, temperature coefficient, dimensions, or exact manufacturer part number. The ambiguity creates a direct sourcing risk. A suffix such as TR can be part of a semiconductor order number or packaging designation, while separate search results show TR references for ANSI post insulators and other catalog codes. These entities have fundamentally different voltages, construction methods, application environments, and procurement formats. Joining them under one specification set would create false technical claims and could produce an unsafe or electrically incompatible replacement. A useful engineering use of this page is therefore identification triage. Search results indicate potential thick-film resistor associations and high-voltage planar resistor documentation, but no complete component record. Before purchasing, specify the source manufacturer, full ordering code, resistance, power rating, package dimensions, operating voltage, and application environment. The Vishay search result specifically associates thick-film planar resistors with power supplies, transformers, and high-voltage environments. For an exact electronic component, request the manufacturer name, full MPN, datasheet, or a photograph of the component markings. If TR is a resistor-series shorthand, complete code such as resistance and power ratings is required. If TR is a suffix on a longer semiconductor MPN, the entire MPN is mandatory. Substituting a generic resistor without those details is not a valid engineering decision. This page distinguishes verified search associations from assumptions and avoids treating unrelated catalog codes as interchangeable parts. It also highlights why package, electrical ratings, and pin compatibility cannot be inferred from a short, non-unique designation. Accurate sourcing begins with resolving the manufacturer and full ordering code before comparison, pricing, or design selection.
WSC251515R00FEA - 15Ω 1W Wirewound SMD Resistor | Vishay Dale
The Vishay Dale WSC251515R00FEA is a 15 Ω ±1% 1 W wirewound chip resistor packaged in the 2515 (J-lead) SMD form factor with AEC-Q200 automotive qualification. Built on a molded thermoset plastic body over an alumina substrate, this part delivers 1 W continuous power dissipation at +70 °C with derating to zero at +275 °C and offers pulse-withstanding capability for inrush and transient events. The 2515 footprint measures approximately 6.35 mm × 3.81 mm with wraparound J-leads compatible with standard reflow soldering. A wirewound surface-mount resistor is a passive component whose resistive element is a coil of fine resistance wire (often a nickel-chromium or copper-nickel alloy such as constantan) bonded to a ceramic substrate, then terminated with metal wraparound or J-lead contacts. Compared to thick-film chip resistors, wirewound SMD parts achieve higher power density, tighter tolerance, lower inductance variation, and superior pulse handling. Within the broader taxonomy, this places the WSC family as a resistor → fixed resistor → wirewound resistor → surface-mount wirewound resistor → power resistor. Key differentiating specifications include ±1% resistance tolerance, ±50 ppm/°C temperature coefficient (per DigiKey/Mouser listing), 1 W power rating at +70 °C, and an operating temperature range of −65 °C to +275 °C. The device is qualified to AEC-Q200 stress standards for automotive electronics and uses 100 % matte-tin (e3) lead-free terminations that withstand MSL-1 (JEDEC J-STD-020) reflow up to +260 °C. Typical use cases include current-sensing shunts for BLDC motor drivers, gate-resistor networks in IGBT/SiC switching power stages, in-rush current limiting on DC bus capacitors, snubber discharge paths, and automotive ECU power conditioning. The wirewound construction gives low parasitic reactance variation versus frequency when used within its designed bandwidth, which keeps measurement accurate in switched-mode power loops. When designing with this part, derate linearly above +70 °C to zero power at +275 °C; do not exceed the 1 W rating at full ambient. Use proper solder pad geometry per the Vishay 2515 land-pattern recommendation to ensure the J-leads form a reliable fillet and to maintain mechanical reliability under thermal cycling.
WSL0805R0680FEA - 68mΩ 0.125W Current Sense Resistor 0805 | Vishay Dale
The Vishay Dale WSL0805R0680FEA is a 68 mΩ ±1% surface-mount metal-element current-sense resistor in an 0805 (2012 metric) package, rated for 0.125 W (1/8 W) continuous power dissipation and qualified to AEC-Q200 for automotive use. A current-sense resistor is a specialized low-ohmic-value component placed in series with a load to develop a small, accurate voltage drop proportional to load current, allowing measurement via an ADC or comparator. Within the broader component taxonomy, it sits under discrete resistors -> chip resistors -> surface-mount resistors -> current-sense resistors -> metal-strip/element current-sense resistors. Unlike general-purpose thick-film resistors, current-sense devices use a low-temperature-coefficient metal alloy element with four-terminal (Kelvin) construction in larger case sizes to minimize the influence of lead resistance; the WSL0805 is a two-terminal device optimized for compact, low-side sensing. Key features of the WSL0805R0680FEA include 68 mΩ ±1% tolerance, a ±75 ppm/°C temperature coefficient, anti-sulfur construction, moisture resistance, and pulse-withstanding capability. The 0805 footprint measures 2.0 mm x 1.25 mm, making it suitable for high-density PCB layouts where board space is constrained. The metal-element technology provides superior pulse and overload handling compared with thick-film alternatives. Technical depth: The metal-strip element is laser-trimmed to a tight resistance value, and the low TCR of 75 ppm/°C keeps the effective ohm value stable across automotive temperature ranges (-65 °C to +170 °C). With 0.125 W continuous rating and 68 mΩ, the resistor can handle a continuous current of approximately 1.36 A (P = I²R) without exceeding rated power, while brief pulses can be much higher thanks to the low thermal mass. Typical applications include DC-DC converter current feedback, battery management system (BMS) charge/discharge monitoring, motor control current sensing, automotive ECU power monitoring, and switch-mode power supply (SMPS) over-current protection. The AEC-Q200 qualification makes it a strong choice for under-the-hood automotive electronics where sulfur and humidity resistance are required. When designing with this part, place it as close as possible to the load and use a 4-wire (Kelvin) routing pattern when available; the 2-terminal pad layout naturally forms a slight parasitic inductance that may matter in fast-switching circuits above 1 MHz. Decoupling the downstream amplifier input minimizes switching noise coupling into the sense signal. This page synthesizes real distributor pricing, AEC-Q200 automotive-grade drop-in alternatives, and practical PCB layout notes not found in the standalone datasheet PDF.
WSL2512R1500FEA - 0.15 Ohm 1W Current Sense Resistor | Vishay
The Vishay Dale WSL2512R1500FEA is a 0.15 Ohm (150 mOhm) ±1% tolerance surface-mount Power Metal Strip current-sense resistor rated at 1W continuous power dissipation, housed in the industry-standard 2512 (6332 metric) chip footprint. Designed around Vishay's proprietary Power Metal Strip resistive element, it delivers a low ±75 ppm/°C temperature coefficient (TCR) with negligible parasitic inductance, allowing accurate four-wire-style measurement even in a two-terminal SMD package. AEC-Q200 qualification, anti-sulfur construction, and moisture-resistant packaging make it suitable for harsh-environment automotive and industrial designs. A current-sense resistor is a low-value, high-precision component intentionally placed in series with a load so the voltage drop across it (V = I × R) can be measured by an amplifier or ADC to determine load current. Compared to general-purpose chip resistors, current-sense parts are optimized for low resistance values, low thermal drift, tight tolerance, and high pulse-power capability. The WSL2512R1500FEA sits in the broader hierarchy: current-sense resistor -> chip resistor -> passive component, and is commonly deployed alongside op-amps, current-shunt monitors, hot-swap controllers, and high-side current-sense amplifiers. Key specifications include 150 mOhm resistance, ±1% tolerance, 1W continuous power at 70 °C (derated linearly to 0 W at 170 °C), ±75 ppm/°C TCR, and a low thermal EMF contribution from the metal-element construction. The 2512 footprint provides 6.4 mm x 3.2 mm body dimensions with a low ~0.5 mm profile, allowing placement on densely populated DC/DC, motor-drive, and battery-management PCBs. Architecturally, the Power Metal Strip element is a solid, self-supported metal alloy resistance strip with solderable terminations, giving low thermal resistance to the PCB land pads. Pulse-withstanding construction allows short-duration overloads (e.g., inrush, short-circuit transients) without resistance shift. Typical applications include DC/DC converter output current monitoring, BLDC motor phase current sensing, USB-C and other load-switch current limiting, battery-pack coulomb counting, and automotive ECU power-rail telemetry. The AEC-Q200 grade also fits under-hood and chassis electronics where temperature cycles and sulfur-bearing atmospheres are common. When designing with this part, derate power aggressively at elevated ambient temperatures and follow the recommended land pattern (Pad A and Pad B larger than standard 2512 chip-resistor pads) so that reflow solder joints survive thermal cycling. Solder-paste volume should be matched to this land pattern to avoid tombstoning. This page synthesizes distributor live-stock pricing, AEC-Q200 cross-brand drop-in alternatives, and PCB-layout guidance for the WSL2512R1500FEA that are not assembled on a single datasheet page.
WSL2816R0100FEH - 10mΩ 2W Power Metal Strip Resistor | Vishay
The Vishay Dale WSL2816R0100FEH is a 10 mΩ (milliohm) surface-mount Power Metal Strip® current-sense resistor rated at 2 W in a 2816 (nonstandard) chip footprint. Built on Vishay's proprietary Power Metal Strip technology with a solid metal element, the part achieves ±1% resistance tolerance, ±75 ppm/°C temperature coefficient, and is qualified to AEC-Q200 for automotive applications, with additional anti-sulfur and pulse-withstanding construction. What is a current-sense resistor? A current-sense resistor is a low-value precision resistor placed in series with a load or supply rail so that the small voltage drop across it (V = I × R) can be measured by an amplifier or ADC. They are critical building blocks in switch-mode power supplies, motor drives, battery management systems, and any closed-loop current-control circuit. Compared to indirect current sensing (shunt + op-amp vs. Hall-effect or Rogowski coil), the shunt-resistor approach offers the lowest cost, highest bandwidth, and best DC accuracy. Key features of the WSL2816R0100FEH include an extremely low 10 mΩ resistance that minimizes insertion loss, a high 2 W power rating that allows continuous current up to ~14 A RMS, ±1% tolerance for tight measurement accuracy, and ±75 ppm/°C TCR for stable reading over temperature. The 2816 footprint (≈4.06 mm × 6.35 mm) is larger than a 2512 footprint, giving the part its high power capability. The metal-element construction eliminates the inductance and thermal EMF issues of wire-wound shunts, while the sulfur-resistant chemistry extends reliability in harsh environments. According to Vishay Dale's WSL series datasheet, the part is also moisture-resistant and pulse-withstanding, making it suitable for inrush, brake, and solenoid applications. Typical applications include automotive ECU power monitoring, brushless DC motor phase current sensing, battery management current shunts, switch-mode power supply output feedback, and industrial inverter leg sensing. The AEC-Q200 qualification makes it directly usable in 12V/24V automotive subsystems such as EPS, BCM, and ADAS power trees. When designing with this part, pay attention to PCB pad layout - the 2816 footprint requires two large solder pads that double as heat-spreaders. Use Kelvin (4-wire) connection when possible to cancel trace resistance. The resistance drifts about +75 ppm/°C, so derate temperature rise by limiting current if your measurement accuracy budget is tight. This page combines distributor pricing, drop-in alternatives, and practical design notes that go beyond the manufacturer datasheet to help engineers select, source, and lay out the WSL2816R0100FEH with confidence.
WSR35L000FEA - 5 mOhm 3W Current Sense Resistor 4527 | Vishay
The Vishay Dale WSR35L000FEA is a 5 mOhm (0.005 Ohm) surface-mount Power Metal Strip current-sense resistor rated at 3 W continuous power, packaged in a 4527 (11.56 mm x 7.49 mm) molded J-Lead SMD format with anti-sulfur construction, AEC-Q200 automotive qualification, ±1% resistance tolerance, and ±110 ppm/°C temperature coefficient. A current-sense resistor is a low-value, precision resistor placed in series with a current path so that the voltage drop across it (V = I × R) can be measured by an amplifier or ADC to infer the load current. This category is part of the passive components family, sitting alongside standard resistors in the surface-mount taxonomy: chip resistor -> current-sense resistor -> metal-strip current-sense resistor -> power current-sense resistor. Power Metal Strip technology uses a proprietary welded metal-alloy resistance element that achieves very low resistance values (down to 0.001 ohm) with excellent pulse-withstanding capability, making it ideal for high-current monitoring. Key specifications include 0.005 ohm resistance (5 milliohnse), ±1% tolerance for accurate current measurement, 3 W power rating at 70 °C derated to zero at 275 °C, ±110 ppm/°C TCR for stable readings across operating temperature, and a 4-terminal (Kelvin) J-Lead layout that minimizes the influence of lead resistance on measurement accuracy. Anti-sulfur construction protects the metal element from sulfur-induced corrosion, critical in industrial and automotive environments where sulfur contamination is common. The WSR35L000FEA uses an all-welded construction of a precision-rolled metal alloy strip molded in a high-temperature thermoset compound, providing pulse-withstanding performance equivalent to wirewound resistors while maintaining the low-inductance characteristics required for switching-converter current waveforms. The 4-terminal J-Lead footprint (two pads for current flow, two pads for voltage sensing) allows true Kelvin connection on the PCB, eliminating parasitic voltage drops in the high-current path from contaminating the sense voltage. Typical applications include DC-DC converter current feedback in switch-mode power supplies, battery management system (BMS) current monitoring, motor control phase-current sensing in BLDC drivers, automotive ECU power monitoring, and load monitoring in power distribution systems. The AEC-Q200 qualification allows deployment under the hood, in chassis modules, and in other automotive stress environments. When designing with this part, route the sense traces as a true 4-wire Kelvin connection back to the amplifier, keep the current-carrying traces wide enough to carry full load without significant IR rise, and verify the PCB land pattern against the J-Lead footprint shown in the Vishay WSR series datasheet.
