0402CS-22NXJLW - 22nH 0402 RF Ceramic Inductor | Coilcraft
The Coilcraft 0402CS-22NXJLW is a 22 nH ceramic-core RF chip inductor with 5% inductance tolerance, a 400 mA current rating, and a 300 mOhm DCR, packaged in an 0402 (1005 metric) surface-mount case. It delivers very high self-resonant frequency performance, with the 0402CS family reaching up to 12.7 GHz and a 2.8 GHz SRF at the 22 nH value, making it a workhorse for RF matching networks. An RF chip inductor is a passive two-terminal component that stores energy in a magnetic field and presents increasing impedance with frequency. Within the passive-component hierarchy (inductor -> RF inductor -> ceramic-core chip inductor), ceramic-core parts sit at the top for Q and SRF because the non-magnetic ceramic core has near-zero core losses compared with ferrite alternatives. Key features of the 0402CS-22NXJLW include its tight 5% tolerance for repeatable matching-network design, its AEC-Q200 qualification for automotive-grade reliability, and its -40 to +125 C operating range that supports under-hood and high-temperature industrial environments. The thin-film construction on the ceramic core yields a Q factor of about 53 at the 22 nH value. Technically, the unshielded wirewound-on-ceramic construction minimizes parasitic capacitance, pushing the self-resonance far above the operating band and keeping insertion loss low in 50-ohm systems. The nickel-barrier termination over solder-coated terminals supports reliable reflow soldering and compatible pick-and-place handling. Typical applications include RF matching networks in front-end modules, Bluetooth, Wi-Fi, GPS, and cellular antenna circuits, plus impedance matching in amplifiers, filters, and VCO tank circuits where compact 0402 size is essential. Design consideration: because the part is unshielded, maintain spacing from adjacent inductors and ground copper to avoid unintended magnetic coupling that shifts matching-network response.

0402CS-3N3XJRW - 3.3nH 840mA RF Inductor | Coilcraft
The Coilcraft 0402CS-3N3XJRW is a 3.3 nH unshielded wirewound ceramic-core RF chip inductor rated for 840 mA with a maximum DC resistance of 66 mOhm, housed in the industry-standard 0402 (1005 metric) surface-mount package. A ceramic-core chip inductor is a passive two-terminal component that stores energy in a magnetic field created by a fine wire wound around a ceramic dielectric. In the passive-component hierarchy, it sits under inductors -> fixed inductors -> RF inductors -> chip inductors. Ceramic cores are preferred for RF work because their low magnetic permeability and low loss allow very high self-resonant frequencies and high Q at gigahertz frequencies, unlike ferrite-core inductors that become lossy above several hundred MHz. Key features of the 0402CS-3N3XJRW include a tight 5% inductance tolerance, a very high self-resonant frequency of up to 12.7 GHz for the series, and qualification to the AEC-Q200 automotive passive-component quality standard. The part is rated for operation from -40C to +125C, making it suitable for automotive and other high-temperature environments where standard commercial inductors cannot survive. Technically, the wirewound construction on a ceramic core delivers stable, predictable inductance with minimal parasitic loss, which is critical in matching networks, filters, and bias tees operating in the VHF-to-microwave range. The 66 mOhm DCR minimizes insertion loss and DC voltage drop in RF choke and bias-feed positions. Typical applications include RF matching networks in 2.4 GHz and 5 GHz radios, antenna tuning circuits, VCO tanks, and supply-line RF chokes for PA and LNA bias circuits. Its tiny 0402 footprint suits dense smartphone, IoT, and automotive telematics boards. Design tip: at 3.3 nH the self-resonant frequency is extremely high, but board parasitics still dominate - keep pads minimal and verify with the Coilcraft SPICE/L numerical models before production.

0402CS-R10XGLW - 100nH 2% RF Chip Inductor | Coilcraft
The Coilcraft 0402CS-R10XGLW is a 100 nH (0.1 uH) ceramic-core wirewound RF chip inductor with 2% inductance tolerance, 2 ohm DCR, and 30 mA rated current, supplied in an SMD 0402 (1005 metric) package. It is AEC-Q200 qualified and rated for operation from -40C to +125C, targeting automotive and other high-temperature RF circuits. A chip inductor is a passive two-terminal component that stores energy in a magnetic field and presents inductive reactance in RF signal paths. Within the passive component hierarchy, it belongs to the fixed inductor family, specifically RF wirewound ceramic-core chip inductors used for impedance matching, resonant tanks, and EMI filtering. The ceramic core is the key differentiator versus ferrite-core chip inductors: ceramic has negligible magnetic loss and near-zero permeability drift, which pushes the self-resonant frequency extremely high and preserves Q at gigahertz frequencies. Key features of the 0402CS-R10XGLW include a very high self-resonant frequency (up to 12.7 GHz for this inductance value per the Coilcraft 0402CS series page), tight 2% tolerance for repeatable filter and VCO tuning, and a fine wirewound construction that delivers consistent performance across temperature. The AEC-Q200 qualification and 125C rating make it suitable for automotive RF modules such as keyless entry, tire-pressure monitoring, and infotainment antennas. Technically, the 100 nH value with low distributed capacitance keeps the usable inductive range well above 1 GHz; above the 12.7 GHz self-resonance the part behaves capacitively. Designers should verify the operating frequency stays comfortably below SRF and keep RF current within the 30 mA rating to avoid self-heating and drift. Typical applications include GPS, Bluetooth, and ISM-band matching networks, LC tank circuits in VCOs, RF chokes, and high-frequency bias tees. It is also used in signal conditioning and EMI filtering in compact automotive modules where board space is minimal. Design tip: keep adjacent ground planes at least one pad width away to minimize parasitic capacitance and preserve the nominal SRF, and verify DCR (2 ohms) in bias-tee insertion-loss budgets. This page adds value beyond the manufacturer catalog by consolidating drop-in alternatives, comparison tables, and design guidance for the 0402CS-R10XGLW in one place.
4448-128L - 100uH 15% High Current Molded SMT Inductor | API Delevan
The API Delevan 4448-128L is a 100 uH surface-mount high-current power toroid inductor with 15% inductance tolerance and a DC resistance of 0.303 ohm, supplied in a molded SMT package from API Delevan's 4448 surface-mount high-current power toroid family. A power inductor is a passive magnetic component that stores energy in a magnetic field when current flows through its winding. Within the component hierarchy, it sits under inductors -> fixed inductors -> power inductors -> toroidal power inductors, a category used throughout power management circuits. Toroidal construction winds the conductor around a doughnut-shaped magnetic core, which confines the magnetic flux within the core and yields lower electromagnetic interference (EMI) compared with equivalent solenoidal (rod or drum core) inductors. The defining features of the 4448-128L are its high current capability, its molded surface-mount construction that protects the toroidal winding during automated handling and reflow soldering, and its tight 15% inductance tolerance, tighter than the 20% tolerance commonly offered on general-purpose power inductors. The low 0.303 ohm DCR reduces conduction losses (I-squared-R heating), directly improving converter efficiency in high-current DC paths. The 4448 family from API Delevan is designed specifically for surface-mount, high-current power applications such as output chokes and energy-storage elements in switching power supplies. The molded body provides mechanical robustness, resistance to winding deformation under vibration, and compatibility with pick-and-place assembly, while the toroid geometry keeps stray flux low for dense mixed-signal boards. Typical applications include switching-mode power supply (SMPS) output filtering, DC-DC converter energy storage, EMI differential-mode filtering, and power-factor-correction or industrial power stages where a compact, high-current SMT magnetics solution is required. When designing with this part, verify that the RMS and peak currents of your converter stay within the rated current of the part, since saturation and thermal rise are the two dominant failure mechanisms for power toroids; consult the manufacturer datasheet for the exact current ratings before finalizing the design.

FP1507R1-R185-R - 185nH 45A Shielded Power Inductor | Eaton
The Eaton FP1507R1-R185-R is a 185 nH shielded drum-core, wirewound SMD power inductor rated for 45 A saturation current and 0.52 mOhm typical DC resistance (DCR) in the Flat-Pac FP1507R series surface-mount package. It is built around a composite drum-core structure with dual flat-wound conductors, delivering the low DCR required for high-current, high-frequency switching regulator and POL converter applications. Power inductors are passive energy-storage components that smooth current ripple in switching regulators, store energy in flyback or SEPIC topologies, and filter EMI in power lines. They sit in the broader hierarchy of passive components, alongside capacitors and resistors, but specifically serve the role of accumulating energy in a magnetic field (E = 0.5 * L * I^2) and releasing it to the load. Within a DC-DC converter, the inductor is the principal energy-transfer element in buck, boost, and buck-boost topologies, and its inductance value, saturation current rating, and DC resistance jointly determine efficiency, ripple amplitude, and thermal performance. The Flat-Pac FP1507R family specifically targets point-of-load converters where footprint, low profile, and very low DCR are all critical. Key features include a 185 nH nominal inductance at 1 MHz test frequency, an unusually high 45 A rated saturation current, and a low 0.52 mOhm DCR. The shielded drum-core construction reduces stray magnetic flux, lowering radiated EMI and allowing adjacent placement of nearby components. RoHS compliance is built into the part number suffix (-R), and a Hi-Pot rating of 250 VDC minimum for 2 seconds at 1.0 mA (conductor to core) provides isolation assurance in safety-critical designs. The dual-conductor flat-wire winding keeps skin-effect and proximity-effect losses low at high switching frequencies, making the FP1507R1-R185-R well suited to multi-MHz buck regulators where conventional round-wire inductors would see significant AC losses. The composite core material allows saturation behavior that is softer than ferrite-only designs, easing transient current spikes in VRM output filters. Typical applications include CPU/GPU VRM output filters, server and data-center POL converters, 48 V-to-PoL intermediate bus converters, industrial DC-DC bricks, and high-current FPGA power rails. Its 45 A rating covers most single-phase and many multiphase VRM outputs. When laying out the PCB, ensure the exposed solder pads of the Flat-Pac footprint are fully wetted and that the land pattern matches the Eaton FP1507R datasheet recommendations. The magnetic field is largely contained by the shield, but high-current return paths should still be kept short. This page synthesizes real-time distributor pricing, verified electrical specifications, drop-in replacement candidates, and PCB-level design notes that are not aggregated on the manufacturer datasheet alone.
FPT705-200-R - 200nH Dual Conductor Power Inductor | Eaton
The Eaton Electronics FPT705-200-R is a 200 nH shielded drum-core, wirewound coupled power inductor rated for 13 A Irms (approximately 40 °C temperature rise) and 25 A I_sat (approximately 2% rolloff at +25 °C), housed in a 4-pin flat-pac surface-mount package measuring 8.0 x 7.1 x 5.35 mm maximum with a ferrite core. A power inductor is a passive energy-storage component that stores energy in a magnetic field when current flows through its winding and releases that energy when the field collapses. Drum-core wirewound inductors use a ferrite or iron-powder core inside a cylindrical bobbin to achieve high energy density, low DC resistance, and high saturation current in a small footprint. Coupled inductors such as the FPT705-200-R integrate two matched windings on a single core, enabling common-mode noise cancellation and higher ripple-current handling than single-winding equivalents. They sit within the broader passive-component hierarchy: inductor → magnetic component → passive component → electronic component. Key features of the FPT705-200-R include a 200 nH open-circuit inductance (OCL) measured at 1.0 MHz, 0.1 Vrms with 0.0 Adc bias at +25 °C, very low DCR of 0.65 mΩ (0.75 mΩ per the Eaton SKU page), shielded drum-core construction that minimizes stray magnetic flux, and a dual-conductor two-turn winding topology. The -R suffix confirms RoHS-compliant lead-free terminations, and the device ships on tape-and-reel packaging compatible with standard SMT placement equipment. Technically, the FPT705 uses a dual-conductor two-turn construction that splits current between two parallel paths, reducing AC winding losses and improving thermal performance under high ripple-current conditions. The ferrite core material provides stable inductance versus DC bias up to the rated I_sat, after which inductance rolls off approximately 2% before entering hard saturation. Low DCR minimizes I²R conduction loss, while the 8.0 x 7.1 x 5.35 mm Flat-Pac footprint supports compact multiphase converter layouts. Typical applications include point-of-load converters, high-current multiphase buck regulators, server and datacom VRM output filters, and Picor Cool-Power ZVS Buck and Buck-Boost regulator families (PI33xx and PI34xx series). The dual-conductor construction is particularly suited to multiphase designs where per-phase inductance must be tightly matched. When designing with the FPT705-200-R, derate I_rms for AC ripple current and verify that peak inductor current remains below I_sat under worst-case transient and load-step conditions. A 40 °C temperature-rise rating assumes still air and a specific PCB copper area; larger copper pours extend current capability further. This page synthesizes Eaton distributor pricing, parametrically compatible drop-in alternatives, and practical PCB-layout notes not found in the standalone datasheet, providing a single reference for engineers evaluating the FPT705-200-R.
FPV1006-150-R - 150nH 25A Shielded SMD Power Inductor | Eaton
The Eaton FPV1006-150-R is a 150 nH shielded drum-core, wirewound SMD power inductor rated for 25 A continuous current (Irms) and 45 A saturation current (Isat), with a maximum DC resistance of 0.41 mΩ, housed in a compact Flat-Pac FPV1006 surface-mount package. The part is designed specifically as an output/storage inductor for high-current point-of-load converters where low DCR, high saturation current, and tight inductance tolerance directly influence ripple, transient response, and steady-state efficiency. A power inductor is a passive magnetic component that stores energy in its core during the ON-time of a switching converter and releases that energy to the load during the OFF-time. The Flat-Pac FPV1006 family from Eaton is positioned in the high-current SMD power inductor hierarchy (power inductor → magnetic passive → passive component), optimized for direct mounting beneath or alongside Vicor Picor Cool-Por ZVS buck and buck-boost regulators. The 10% inductance tolerance (M-grade) provides predictable energy storage across production lots, while the shielded drum-core construction minimizes stray magnetic field that could couple into adjacent traces or inductors on the PCB. Key electrical features include 150 nH nominal inductance measured at 100 kHz / 0.1 V, a remarkably low DCR of 0.41 mΩ maximum that limits I²R conduction loss to approximately 0.26 W at 25 A, and a saturation current of 45 A — meaning the inductance rolloff remains well above the operating current at typical 25-30 A loads. The ferrite core material enables stable inductance across temperature while keeping core loss modest at switching frequencies of 1-2 MHz common in high-density POL converters. Typical applications for the FPV1006-150-R include the output filter of 48 V-to-1 V to 12 V point-of-load converters built around Vicor Picor PI34xx/PI35xx ZVS buck regulators, high-current CPU/GPU core voltage rails in telecom and datacom hardware, 48 V bus-powered industrial PoL bricks, and compact DC-DC stages in space-constrained server sleds. The combination of low DCR and high Isat allows designers to push switching frequency higher — reducing output capacitance — without exceeding thermal or saturation limits. When designing with this part, pay particular attention to DC bias: at 25 A continuous, the FPV1006-150-R typically operates at roughly 55% of its 45 A Isat rating, which preserves inductance and avoids audible buzzing. The 2-terminal SMT footprint simplifies PCB layout and reflow assembly on standard lead-free profiles. This page synthesizes distributor pricing, same-Flat-Pac alternatives, and Vicor-paired converter recommendations that are not aggregated in the standalone Eaton specification sheet.
HCV1206-R48-R - 480nH 16A High-Current SMD Inductor | Eaton
The Eaton HCV1206-R48-R is a 480 nH unshielded wirewound power inductor rated for 16 A saturation and 37 A Irms, supplied in a low-profile surface-mount 12 mm x 6 mm (HCV1206) flat-wire package. It is part of Eaton's Coiltronics HCV1206 high-current power inductor family and is specified for -55 °C to +125 °C operation, making it suitable for demanding thermal environments including automotive and industrial power-conversion stages. A power inductor is a passive magnetic component that stores energy in its magnetic field when current flows through its windings and releases that energy when current is interrupted; in switching power supplies, the inductor smooths current ripple, sets the converter's energy-transfer characteristic (the L·di/dt term), and forms the output filter together with a capacitor. The HCV1206 family uses a flat-wire winding on a drum-core ferrite body that yields lower DC resistance (DCR) than equivalent round-wire parts, reducing conduction loss and improving overall converter efficiency at high DC bias currents. Key features of the HCV1206-R48-R include a maximum DCR of 3.15 mΩ (typical), 480 nH ±10 % open-circuit inductance measured at 100 kHz / 0.1 Vrms / 0 Adc, an etched flat-wire construction for repeatable DCR and saturation behavior, and a solderable surface-mount land pattern with coplanarity specified to 0.1 mm. According to the Eaton HCV1206 datasheet, Irms is defined as the DC current that produces approximately 40 °C temperature rise without core loss, and the part is derated for AC ripple. The HCV1206 footprint also provides a dedicated pin-3 mounting-stability terminal that increases mechanical robustness against vibration and thermal-cycling stress. Typical applications include high-current point-of-load (POL) and VRM inductors, buck and multiphase VR converter output chokes, automotive 48 V mild-hybrid DC-DC converters, server and telecom silver-box output filters, and Class-D amplifier output filters. The flat-wire geometry also reduces skin-effect losses at higher switching frequencies compared to round-wire equivalents. When designing with the HCV1206-R48-R, place the part over a continuous ground/power copper pour to spread heat, and observe the 40 °C temperature-rise derating curve to size DC current correctly; at high ripple, derate further to keep total losses (DCR·I² + core loss) within the thermal budget. This page consolidates distributor pricing, parametric drop-in alternatives, and practical PCB thermal notes not found in the stock datasheet.
HCV1707R1-R48-R - 480nH 32A Power Inductor | Eaton
The Eaton Electronics Division HCV1707R1-R48-R is a 480 nH unshielded drum-core, wirewound high-current SMD power inductor rated for 32 A Irms and 55 A Isat, with a low 1.7 mOhm (typical) DCR, packaged in a 3-lead nonstandard SMT footprint. It belongs to Eaton's HCV1707 high-current power inductor family engineered for point-of-load (POL) conversion, high-current CPU/GPU VRM outputs, and 48 V bus buck regulator output filter stages. What is a power inductor? A power inductor is a passive magnetic component that stores energy in its magnetic field during the ON-switch cycle of a switching regulator and releases it during the OFF-cycle, smoothing output current and forming the LC output filter with the regulator's output capacitor. Power inductors are essential building blocks in switch-mode power supplies (SMPS), DC-DC converters, and voltage regulator modules (VRMs), sitting within the broader hierarchy: inductor -> passive component -> magnetic component -> electronic component. In high-current buck regulators (e.g., Eaton/Vicor PI354x Cool-Power ZVS family mentioned in datasheet references), the output inductor directly determines ripple current, transient response, and steady-state efficiency. Key features of the HCV1707R1-R48-R include a 480 nH nominal OCL (open-circuit inductance) measured at 100 kHz / 0.1 Vrms, low DCR for minimal I^2R loss, an operating temperature range up to +125 C (per Eaton datasheet derating guidance), and a 3-terminal SMD construction suitable for reflow soldering. The drum-core wirewound architecture offers a high saturation current ceiling relative to its footprint and is optimized for switching frequencies from approximately 100 kHz to 1 MHz. Technically, the HCV1707 family uses a ferrite drum core with a single-layer or few-turn heavy-gauge winding to balance DCR, saturation flux density, and AC winding losses. Eaton rates Irms as the DC current producing approximately 40 C temperature rise without core loss, and Isat as the current causing a defined inductance drop (typically 20%). Designers should derate for AC currents and verify worst-case hotspot under PCB layout, copper thickness, and adjacent thermal conditions. Typical applications include 48 V to POL buck regulator output filters, server and telecom VRM inductors, high-current LED driver chokes, and Class-D audio amplifier output filters. In Eaton's reference Cool-Power ZVS buck regulator designs (e.g., PI3546-00-LGIZ referenced in datasheet collateral), the HCV1707 family is the recommended companion output inductor. When designing with this part, pay attention to PCB pad layout - the 3-lead nonstandard pattern requires careful footprint matching. Verify peak-to-peak ripple (delta_IL = (V_in - V_out) * V_out / (V_in * f_sw * L)) stays within the inductor's Isat envelope, and derate to +125 C max hotspot per the manufacturer's worst-case derating guidance.

IHLP2020BZER4R7M11 - 4.7µH Shielded Power Inductor 3.2A | Vishay
The Vishay Dale IHLP2020BZER4R7M11 is a 4.7 µH shielded, molded, wire-wound SMD power inductor rated for 3.2 A continuous current with a maximum DC resistance (DCR) of 81.3 mΩ, packaged in the IHLP-2020BZ case size (5.0 mm × 5.0 mm × 3.0 mm max profile). It is part of the IHLP-2020BZ-11 family, which uses a powdered-iron metal-composite core to deliver the lowest DCR-per-µH ratio in the IHLP lineup, along with ultra-low buzz noise thanks to its molded construction. A shielded molded inductor (also called a power choke or SMD power inductor) is a passive component that stores energy in a magnetic field and resists changes in current. It is the workhorse of switched-mode power supplies, where it smooths current ripple, filters EMI, and forms the LC tank that sets converter switching frequency. The IHLP family sits in the power-management component hierarchy: power inductor → magnetic component → passive component → electronic component, and is built for high-current, low-profile DC-DC converter applications. Key features include a low DCR of 81.3 mΩ maximum (for high efficiency and low I²R loss), ±20% inductance tolerance, magnetic shielding that minimizes stray field coupling to nearby noise-sensitive analog/RF circuits, and an operating temperature range suitable for reflow soldering (J-STD-821). The molded construction eliminates audible buzz under high-ripple conditions and provides mechanical robustness in automotive and industrial environments. The IHLP-2020BZ-11 uses a composite iron-powder core pressed around the windings, which suppresses acoustic noise and gives stable inductance versus DC bias. Vishay rates the 4.7 µH value at 3.2 A saturation current and 81.3 mΩ DCR, meaning a typical 12 V buck converter built around this part can deliver well over 1 A to the load while staying inside the inductor's thermal envelope. Typical applications include high-current point-of-load (POL) buck regulators, low-voltage distributed power in servers and telecom cards, FPGA and ASIC core voltage rails, Class-D audio output filters, and DC-DC converters in automotive infotainment and ADAS modules where the part's automotive-grade manufacturing discipline and compact 2020 footprint are valuable. When designing with this inductor, derate saturation current by at least 20% for high-temperature operation and verify DC bias behavior against the manufacturer's L vs I curve. The composite core provides soft saturation, but continuous operation near rated current still raises winding temperature. This page consolidates distributor pricing, drop-in same-package alternatives, and engineering design guidance that is not found on any single manufacturer or distributor page.
IHLP2525CZER1R0M01 - 1µH 11A Shielded Power Inductor | Vishay Dale
The Vishay Dale IHLP2525CZER1R0M01 is a 1 µH shielded, molded, low-profile power inductor rated for 11 A saturation current and 10 mΩ maximum DC resistance (DCR), packaged in a compact 2525 (6.47 mm x 6.86 mm x 3.0 mm) SMD case. It is part of the IHLP-2525CZ-01 commercial/industrial high-saturation series and is designed for high-current DC/DC converter and power-supply filtering applications. A power inductor is a passive energy-storage component that stores energy in a magnetic field when current flows through its coil and releases that energy to maintain current flow during switching transitions. In switch-mode power supplies, an inductor smooths the switched current and defines the energy-transfer cycle; higher saturation current allows the inductor to sustain larger peak currents without losing inductance, and lower DCR reduces I²R conduction loss. The IHLP family belongs to the broader categories: inductor → magnetic component → passive component, and sits in the power-management sub-tree of a power-supply block diagram. Key features include a composite shielded construction that minimizes stray magnetic field and audible buzz noise, the lowest 3.0 mm profile in its 2525 footprint, excellent DC/DC energy storage up to 5 MHz, and suitability as a filter inductor up to its self-resonant frequency (SRF). Per the datasheet features list, the part handles high transient current spikes without hard saturation and is 100% lead-free and RoHS-compliant. The IHLP2525CZER1R0M01 uses a molded metal-alloy powder core rather than a ferrite core; this construction distributes the magnetic flux inside a homogeneous medium, suppressing the sharp saturation knee found in ferrite inductors. The result is a soft saturation curve: inductance rolls off gradually as current increases, making the part tolerant of high di/dt transients typical of multi-phase VRMs and POL regulators. The shielded composite body also reduces acoustic noise and EMI radiation by confining the field within the device body. Typical applications include high-current point-of-load (POL) regulators, multi-phase VRMs for servers and workstations CPUs/GPUs, telecom base-station DC/DC bricks, portable device chargers, and battery-powered systems where the low 3.0 mm profile is required for thin enclosures. It is commonly used in voltage rails sequencing on FPGAs, ASICs, and graphics processors where 1 µH power inductors are standard. According to the Vishay datasheet, it is well-suited to filter inductor applications up to the part's self-resonant frequency. When designing with this device, derate the saturation current against temperature: Vishay specifies 11 A as the typical Isat at 25 °C, and the actual allowable current decreases at higher ambient temperatures. Confirm the operating point against the datasheet's DC current vs. inductance roll-off curve. This page synthesizes distributor pricing, drop-in IHLP-2525 alternatives, application examples, and PCB layout notes beyond the manufacturer datasheet to support faster design-in.
IHLP2525CZER2R2M06 - 2.2µH 8A Shielded Power Inductor | Vishay Dale
The Vishay Dale IHLP2525CZER2R2M06 is a 2.2 µH shielded molded power inductor rated for 8 A continuous current with a maximum DC resistance of 17.73 mΩ, supplied in a surface-mount 2525 (6.86 mm x 6.47 mm) case. Part of the IHLP-2525CZ-06 low-profile/high-current family, it uses a powdered-iron core and wirewound construction to deliver high saturation current and low core loss in a compact footprint. A power inductor is a passive electronic component designed to store energy in a magnetic field when current flows through its coil winding. In switching power supplies, inductors smooth current ripple, filter noise, and temporarily hold energy during the switch-off phase of a converter. The shielded-molded construction places a magnetic shield around the winding, which dramatically reduces stray electromagnetic fields that could otherwise couple into nearby traces or sensitive analog circuits. Shielded molded inductors belong to the broader category of SMD power inductors within passive components. Key features include a 2.2 µH nominal inductance with ±20% tolerance, 8 A rated saturation current handling capability, 17.73 mΩ maximum DCR for high efficiency, and a 100 kHz reference test frequency per Vishay's datasheet. The molded package provides mechanical robustness and uniform magnetic shielding, while the low profile supports space-constrained designs such as POL (point-of-load) converters and portable electronics. The IHLP-2525CZ-06 family targets DC-DC converter inductor applications. The powdered-iron core allows soft saturation behavior, meaning inductance decreases gradually rather than collapsing abruptly under overcurrent conditions. This characteristic helps prevent catastrophic inductor failures and supports predictable converter operation under transient loads. The shielding also reduces acoustic noise from magnetostriction effects. Typical applications include VRM (voltage regulator module) inductors for notebook and server CPUs, POL buck/boost converters in distributed power architectures, battery-powered portable devices, graphic card power circuits, and as output filter inductors in high-current point-of-load regulators. When designing with this part, confirm that peak current (including ripple) stays below the saturation rating and that DCR power losses fit within the thermal budget of the PCB layout. Adequate copper pad geometry and thermal vias under the inductor footprint help dissipate heat.

IWAS3222CZEB190JR1 - 19.6 uH Shielded Wireless Coil
The Vishay Intertechnology IWAS3222CZEB190JR1 is a shielded wireless charging receiver coil with a nominal inductance of 19.6 uH, a specified tolerance of 5%, and an operating current rating of 2.4 A. The component is presented by distributors as a one-coil, one-layer receiver assembly for wireless power-transfer systems. Its shielded construction provides environmental protection and moisture resistance in high-humidity conditions up to 90% RH. A wireless charging receiver coil is an inductive component used to capture energy transferred from a transmitting coil through electromagnetic induction. In the power path, the receiver coil converts magnetic flux into an electrical signal that is then rectified, filtered, and regulated by the receiving electronics. The coil therefore sits at the interface between the wireless power field and the device's power-management circuit. The IWAS3222CZEB190JR1 combines 19.6 uH inductance with a 2.4 A current rating, making its electrical scale suitable for receiver-side power-transfer designs where the associated rectifier, capacitor, and regulator must be matched to the coil's inductance and resistance. The distributor listing also identifies a resistance value of 357 mOhm, while the manufacturer page identifies the product as a shielded wireless charging receiver coil. Its specialized shield coating is intended to improve environmental protection and moisture resistance, particularly in humid operating environments. This makes the component relevant to portable electronics, wireless power accessories, and other systems requiring a robust receiver coil, although final suitability must be validated against the complete transmitter, receiver, thermal, mechanical, and electrical design. The most important design consideration is system-level matching. The coil inductance, DC resistance, current capability, shield geometry, and operating temperature must be evaluated together with the transmitter characteristics and downstream regulator requirements. The manufacturer states that customers must validate that the product is suitable for a particular application because parameters and performance can vary by application and over time. This page consolidates the verified distributor specifications, manufacturer environmental claims, source links, and application guidance for engineers evaluating IWAS3222CZEB190JR1. It also distinguishes verified data from information that is not present in the supplied sources, avoiding assumptions about package dimensions, exact pricing, or lifecycle status.
IWTX4646DCEB240JR1 - 24µH Wireless Charging Tx Coil | Vishay Dale
The Vishay Dale IWTX4646DCEB240JR1 is a wireless charging transmitter coil rated 24 µH nominal inductance with 5% tolerance and a 75 mOhm typical DCR, designed for use as the primary (TX) coil in inductive power transfer systems supporting up to 20 A peak current. The coil is constructed in a 1-coil, 2-layer winding architecture in a 46 mm x 46 mm outline and is supplied together with its companion ferrite shielding plate for improved coupling and reduced stray field. A wireless charging transmitter coil is a precision-wound inductor that forms the primary half of a loosely-coupled transformer across an air gap. When driven by an LC resonant inverter at the WPC Qi or proprietary frequency (typically 100 kHz to 205 kHz), it generates an alternating magnetic flux that the receiver coil converts back into electrical energy. Transmitter coils sit in the power-management subsystem alongside gate drivers, resonant controllers, and current-sensing circuitry, and are selected for their inductance tolerance, Q-factor, DC resistance, saturation current, and overall dimensions. Key features of the IWTX4646DCEB240JR1 include a tightly-controlled 24 µH ±5% inductance for predictable resonance tuning, a low 75 mOhm DCR that limits I²R heating during continuous 20 A pulses, a high Q-factor for efficient energy transfer across the gap, and a matched ferrite shield that concentrates flux toward the receiver pad. The 46 mm x 46 mm footprint aligns with the WPC Qi Extended Power Profile (EPP) 30 W and 15 W coil pad layout, allowing integration into multi-coil arrays. The architecture uses Litz-wire construction in a flat spiral pattern that minimises skin-effect losses at 100-205 kHz switching frequencies. The integrated ferrite backing plate shapes the magnetic field, improves coupling coefficient (k) to the receiver, and shields sensitive electronics on the transmitter PCB from the alternating flux. The 2-layer winding geometry balances inductance density against physical size, delivering 24 µH in a thinner stack than single-layer designs. Typical applications include Qi-compliant wireless charging pads for smartphones, tablets, and wearable devices, in-vehicle Qi phone chargers, cordless kitchen-appliance charging bases, and industrial wireless power transmitters for sensors and IoT endpoints. The 20 A saturation capability also supports fast-charge applications above the baseline 5 W Qi baseline-power profile (BPP). When designing with this coil, ensure the resonant tank capacitance is sized to the actual inductance value measured on your lot — Vishay specifies ±5%, and a 5% shift in L shifts the resonant frequency by approximately 2.5%. Keep the receiver coil laterally aligned with the ferrite shield centre, and maintain at least 5 mm of clearance from sensitive analog circuitry on the same PCB. This page synthesises distributor pricing, parametric comparison, and design considerations not found in the standalone Vishay product brief.
IWTX47R0DAEB6R3JR1 - 6.3µH Wireless Charging Transmitter Coil | Vishay Dale
The Vishay Dale IWTX47R0DAEB6R3JR1 is a 6.3 µH wireless charging transmitter coil with integrated environmental shield, designed for resonant inductive power transfer in Qi-compliant and proprietary wireless charging transmitter (Tx) stages. The coil is constructed as a single-layer litz-wire winding with a specialized shield coating rated for operation in high humidity environments up to 90 % RH, and it is supplied as one coil in the IWTX series family of transmitter coils. Per the manufacturer datasheet, the inductance is 6.3 µH at 5 % tolerance, and the DC resistance (DCR) is 40 mΩ, enabling low loss at the typical 100 kHz to 200 kHz operating frequencies used in wireless charging. A wireless charging transmitter coil is a passive inductive component that forms the primary side of an air-gap-coupled transformer; energy is driven into the coil by an inverter class-D or full-bridge stage, generating an alternating magnetic flux that the receiver coil converts back to DC. Within the broader passive component taxonomy, this device sits in the inductor family, specifically the wireless-charging-coil subcategory, which sits at the boundary between power inductors and antenna coils. Environmental-protection shields on transmitter coils reduce radiated emissions, contain stray flux within the active coupling zone, and protect the litz wire from oxidation and humidity-driven degradation in consumer charging pads, industrial tooling chargers, and in-cabin automotive Qi chargers. Key features specified by Vishay for this part include a 5 % inductance tolerance (3JR1 in the part number denotes 5 % inductance tolerance per Vishay's internal coding), a rated current of 22 A supported by the low-DCR litz-wire geometry, and a single-layer 1-coil construction that simplifies PCB-side assembly. The shielding is an integrated ferrite-loaded coating (rather than a discrete shield plate), allowing OEMs to drop the coil + shield assembly onto a flat PCB or molded plastic surface without secondary shielding hardware. Operating temperature range is rated for standard industrial passive-component environments. The litz-wire construction, which bundles multiple fine insulated strands, significantly reduces skin-effect and proximity-effect losses at the 100-200 kHz switching frequencies used in Qi and proprietary inductive links, compared to solid-wire equivalents of the same total cross section. The environmental shield further lowers radiated EMI by attenuating high-frequency harmonic content of the coil's magnetic near-field. Together these features support cleaner EMI signatures and reduced thermal rise in continuous-power transmitter applications. Typical applications include Qi-compliant wireless charging transmitter pads for smartphones and wearables, inductive charging cradles for medical and industrial handheld devices, in-cabin automotive phone chargers operating on 12 V battery rails, and proprietary resonant power-transfer stages in industrial robotics, AGV fleets, and low-power EV charging accessories. Each use case benefits from the coil's low-DCR thermal behavior and its shielded construction. When designing with this transmitter coil, plan the PCB cut-out, bobbin footprint, and thermal sink path before layout. The shield coating must remain intact during handling and assembly; pin and pad layout must respect the coil's specified A and B dimensions from the datasheet mechanical drawing.
IWTX47R0EBEB240JR1 - 24µH Wireless Charging Tx Coil 75mΩ | Vishay Dale
The Vishay Dale IWTX47R0EBEB240JR1 is a wireless charging transmitter coil with 24µH nominal inductance, 5% tolerance, 75mΩ maximum DC resistance, and 20A saturation current rating, supplied with an integrated ferrite shield for Qi-compliant inductive power transfer designs. The coil is wound on a single former as a 2-layer winding optimized for transmitter-side magnetic flux coupling. A wireless charging transmitter coil is the resonant magnetic element on the primary (TX) side of an inductively-coupled power transfer link. The coil, together with a matching network capacitor, forms an LC tank that resonates at the Qi-specified 110-205 kHz band (low-power Qi) or at higher bands used by fast-charging proprietary protocols. The shield below the coil contains the magnetic flux and steers it toward the receiver coil while limiting stray field emissions. TX coils are larger and rated for higher current than RX coils because the transmitter actively drives the resonant current, while the receiver only captures it. Key features of this part include the 24µH inductance at 200 kHz, 5% inductance tolerance for predictable resonant tuning, 20A current rating which keeps I²R losses under 1W at full drive, and 75mΩ maximum DCR which limits conduction loss and thermal rise. The integrated shielding reduces the bill of materials versus a separate ferrite sheet and improves coupling alignment tolerance with the receiver pad. The IWTX47R0EBEB240JR1 is built on a single-layer double-sided PCB-style flat winding with an attached ferrite base. The flat, low-profile construction (~3.5 mm height typical) is optimized for placement under enclosures and integrates directly onto a transmitter PCB or a charging pad surface. Termination is by flying lead for soldering to the host PCB. Typical applications include Qi-compliant wireless charging transmitters, charging pads for smartphones, smartwatches, and earbuds, industrial inductive power modules, medical device battery chargers, and automotive in-cabin charging cradles. The 24µH inductance makes it well-suited to low-power (5W) Qi BPP and mid-power (up to 15W) Qi EPP transmitter topologies paired with a half-bridge or full-bridge inverter. When designing with this part, ensure the resonant capacitor is selected to place the LC tank at the protocol target frequency and that thermal management accounts for sustained 20A drive current in enclosed housings. Always validate coupling coefficient with the chosen receiver coil over the full range of device placement positions.

IWTX5547EEEB8R5KF1 - 8.5µH Wireless Charging Tx Coil | Vishay Dale
The Vishay Dale IWTX5547EEEB8R5KF1 is a single-layer wireless charging transmitter coil with a shielded construction, rated at 8.5 µH inductance, 56 mΩ maximum DC resistance, and 5 W to 15 W power handling, designed to comply with the Qi standard MP-A8 reference topology for inductive power transfer. A wireless charging transmitter coil (a Tx coil) is a flat wound inductor that converts high-frequency alternating current from a driver IC into an alternating magnetic field, which a corresponding receiver coil in a portable device converts back into DC power to charge a battery. Within the power management ecosystem, Tx coils sit between the DC-DC converter and the antenna stage; they are part of the inductive coupling subassembly that defines the Wireless Power Consortium's Qi standard interoperability envelope. The IWTX-family Mp = Wireless Charging Transmitter Coil, packaged as a self-shielded single-layer assembly with integrated ferrite backing, eliminates the need for a separate shield plate on the PCB. Key specifications include an 8.5 µH nominal inductance designed for resonance in the 100-200 kHz Qi band, a Q factor reflecting the coil's low-loss winding, a 56 mΩ maximum DC resistance (DCR) that limits I²R losses at high currents, and a 5 W to 15 W power rating suitable for fast-charging smartphones and small electronics. The integrated magnetic shield reduces stray-field emissions, simplifying EMI compliance for Qi MP-A8 systems. Operating and storage temperature spans of -40 °C to +105 °C support automotive, industrial, and consumer environments. The coil's flat form factor and pre-attached shielding deliver consistent inductance and coupling distance without additional mechanical assembly. Technically, the IWTX5547EEEB8R5KF1 employs a single-layer winding over a precision bobbin with a high-permeability ferrite backing plate. The pre-tuned inductance targets resonance with common Qi transmitter ICs, reducing matching network design effort. The integrated shield redirects magnetic flux downward toward the receiver and limits backward emission toward the PCB, which improves EMC margins and reduces coupling losses during misalignment. Typical applications include Qi-compliant wireless charging transmitters for consumer smartphones and tablets, automotive in-cabin charging pads, medical and industrial handheld charging cradles, 5 W to 15 W wireless power reference designs, and Qi MP-A8 resonant transmitter modules. The coil is well-suited to designs that adopt WPC MP-A8 reference layouts. When integrating this Tx coil, follow the recommended landing pattern, observe the minimum standoff distance to the receiver, and verify the matching network with the chosen transmitter IC. Adequate thermal management is required at 15 W continuous operation to keep the winding within its 40 °C temperature-rise rating.

LQH32CN100K23L - 10uH 300mA Wirewound Inductor | Murata
The Murata Electronics LQH32CN100K23L is a 10 uH unshielded drum-core wirewound power inductor with a maximum DC resistance of 572 mOhm, a rated current of 300 mA, and an inductance tolerance of +/-10 percent, supplied in a surface-mount 1210 (3.2 x 1.6 mm) nonstandard footprint chip package. A wirewound chip inductor is a passive two-terminal component that stores energy in a magnetic field created by copper wire wound around a magnetic core. Within the component hierarchy, it belongs to the inductor family of fixed inductors, which in turn sit inside the broader magnetics and passive components category of surface-mount devices. Unlike multilayer chip inductors, wirewound drum-core types achieve higher inductance values and better saturation behavior in a compact footprint, which is why they are widely used as power chokes and choke coils in DC supply lines. Key differentiating features of the LQH32CN100K23L include its 10 uH inductance measured at 1 MHz, the ferrite drum core construction, and the unshielded open-magnetic-circuit design that minimizes package height and cost. The 572 mOhm maximum DCR keeps copper losses low at the 300 mA rated current, and the tight +/-10 percent tolerance supports predictable filter corner frequencies. Technically, the wirewound-on-ferrite-drum architecture delivers a stable inductance value with a self-resonant frequency suitable for choke service; because the winding is exposed in an unshielded structure, flux leakage and coupling to adjacent components must be considered in layout. Typical applications include DC-DC converter output filtering, power supply choke coils, noise suppression on power rails, and general-purpose signal-line choke service in consumer, industrial, and communication equipment. For design, derate the 300 mA rating as ambient temperature approaches the upper operating limit, and verify self-resonant behavior at your operating frequency. Estimated power loss at rated current is approximately 51 mW from I-squared-R (0.3 A squared times 0.572 Ohm). This page adds value beyond the Murata datasheet by consolidating distributor pricing context, drop-in alternatives, practical design notes, and an AEO-optimized FAQ in one place.
LQH32CN1R0M23L - 1uH 800mA Wirewound Inductor | Murata
The Murata Electronics LQH32CN1R0M23L is a 1 uH unshielded drum-core wirewound power inductor rated for 800 mA with a maximum DC resistance of 117 mOhm, housed in a nonstandard 1210 (3.2 x 2.5 mm) surface-mount package with a tolerance of +/-20%. A fixed inductor is a passive two-terminal component that stores energy in a magnetic field when current flows through its winding. Within the passive-component hierarchy, it sits under inductors and coils, alongside chokes and ferrite beads, and serves power management and analog signal chains by filtering ripple, smoothing current, and forming LC resonant tanks. Drum-core wirewound construction achieves high inductance per unit volume at low cost, at the trade-off of an open magnetic structure. Key features of the LQH32CN1R0M23L include its 1 uH nominal inductance with M-code (+/-20%) tolerance, an 800 mA rated current that supports Buck-boost and step-down converter output stages in the several-hundred-milliamp class, and a low 117 mOhm maximum DCR that limits conduction losses and I2R heating. The wirewound drum-core design provides stable inductance across frequency and temperature for general-purpose power rails. Technically, the unshielded open-flux construction means magnetic field coupling to neighboring components must be considered during layout, but it also yields lower cost and smaller profiles than shielded types. The 1210 footprint accepts standard reflow soldering and is compatible with pick-and-place assembly. Typical applications include DC-DC converter output filtering in consumer and industrial electronics, power-supply input chokes, LED driver current smoothing, and general LC filter networks on 4G modules and microcontroller boards. Designers should derate the 800 mA rating if the part will see elevated ambient temperatures or high ripple current, and should keep sensitive analog traces away from the open flux path of the unshielded core. This page adds information gain beyond the datasheet: distributor pricing tiers, drop-in same-footprint alternatives, and layout guidance synthesized from manufacturer and distributor sources.
LTF5022T-4R7N2R0-D - 4.7uH Shielded Wirewound Inductor | TDK
The TDK LTF5022T-4R7N2R0-D is a 4.7 microhenry (uH) magnetic-shielded wirewound SMD power inductor rated for 2.03 A continuous current (per Mouser listing) and 2.18 A on the DigiKey listing, with a maximum DC resistance of 0.074 ohm (74 mOhm) measured by DigiKey and approximately 0.062 ohm quoted by Mouser depending on test conditions. It is part of the LTF5022 family of low-profile (max 2.2 mm height) shielded drum-core inductors for power circuits, packaged in a nonstandard 5.0 x 5.2 mm land pattern with halogen-free construction and an operating temperature range of -40 C to +105 C (including self-temperature rise). A power inductor is a passive energy-storage component used in switching power supplies and DC-DC converters to smooth current, filter EMI, and store energy in a magnetic field. Power inductors sit hierarchically within inductors & coils, passive components, and broader power-management circuits, where they are commonly paired with a switch IC, input/output capacitors, and a feedback loop to form a buck, boost, or SEPIC topology. The magnetic shield (drum core) construction of the LTF5022 family confines flux to the device body, reducing stray electromagnetic interference with nearby traces. Key features of this specific part include its 4.7 uH nominal inductance, sub-100 mOhm DCR that limits conduction loss at full load, and 2 A-class current rating suitable for point-of-load conversion stages. The LTF5022 family is targeted at thin-screen TVs, LCDs, DVC, DSC, and similar compact consumer-electronics power rails. The -D suffix denotes the AEC-Q200 automotive-grade screened variant of the LTF series. The LTF5022 uses a ferrite drum core with a wirewound winding, an architecture that delivers high saturation current and low DCR within a 5.0 x 5.2 mm footprint. Its magnetic-shield construction minimizes acoustic noise and reduces radiated EMI, which is critical when the inductor is placed near sensitive analog or RF circuitry. The halogen-free materials support RoHS-compliant end products. Typical applications include DC-DC converter output filter stages in flat-panel TVs and LCD monitors, point-of-load regulation for set-top boxes and digital still cameras, and POL supplies in automotive infotainment where the AEC-Q200 -D variant is required. The wide -40 C to +105 C operating range also suits industrial equipment enclosures with limited airflow. When designing with this part, verify saturation current (Isat) and temperature-rise current (Irms) against the maximum DC load in your converter. Place the input capacitor close to the switching IC and the output capacitor close to the inductor to minimize parasitic loop inductance and high-frequency ringing on the switching node. This page synthesizes distributor pricing, parametric data, and drop-in alternatives not found in the manufacturer datasheet alone, helping engineers shorten their BOM validation cycle.
MFBW1V2012-301-R - 300Ω Ferrite Bead, 0805, 2A | Eaton
The Eaton Electronics Division MFBW1V2012-301-R is a multilayer chip ferrite bead rated at 300 Ohms impedance at 100 MHz and 2.0 A continuous current, packaged in the industry-standard 0805 (2012 metric) footprint. It is part of Eaton's MFBW1V2012 family of high-impedance multilayer ferrite chip beads designed for power-line EMI suppression, with a maximum DC resistance of 200 mOhm and operating temperature range of -55 °C to +125 °C. As of 2026-10-09 the part is in stock at major distributors including Mouser, DigiKey, TTI and LCSC, with LCSC pricing starting from $0.0583 unit. What is a ferrite bead? A ferrite bead (also called a chip bead, ferrite inductor, or EMI suppression bead) is a passive component that uses ferrite ceramic material to suppress high-frequency noise on power and signal lines. It is placed in series with a conductor where its frequency-dependent impedance — low at DC, high at RF — attenuates EMI/RFI while passing DC and low-frequency signal current virtually unattenuated. In the electronic component hierarchy, ferrite beads sit under Inductors & Coils > Filters in the Passive Components tree and are functionally classified as single-channel EMI filters. Key features of the MFBW1V2012-301-R include a high 300 Ω impedance at 100 MHz that effectively attenuates conducted emissions above 30 MHz where most digital harmonics and switching-converter noise concentrate, while only dissipating 200 mΩ × 2 A² ≈ 0.8 W of I²R loss at full rated current. The 0805 footprint is one of the most common SMD passive sizes, making the part easy to design in next to ICs, connectors, and DC/DC converters. The multilayer construction is more robust than wire-wound equivalents under thermal cycling and mechanical shock. Typical applications include DC power-rail decoupling in USB 2.0/3.0 ports, HDMI and DisplayPort lines, switching-converter output filtering, and EMC suppression on microcontroller power pins. The 2 A current rating covers most sub-rail applications including USB VBUS, 3.3 V/5 V logic rails, and PoE phantom feeds. Eaton's datasheet specifies the impedance curve across frequency from 1 MHz to 1 GHz, useful for EMI simulation and filter design. Design considerations: verify that the maximum DC bias current (2 A) is not exceeded in the application, since impedance drops significantly as bias current approaches saturation. For multi-rail designs, place the bead on each affected rail immediately adjacent to the connector or noise source. The 0805 footprint allows 1 A continuous operation without additional copper thermal management. Compared to a common-mode choke, the MFBW1V2012-301-R is asymmetric — it suppresses only one conductor — but at lower cost and smaller PCB area.

NRS3015T100M - 10uH 700mA Semi-Shielded Power Inductor | Taiyo Yuden
The Taiyo Yuden NRS3015T100M is a 10 uH semi-shielded drum-core, wirewound SMD power inductor rated for 700 mA with a maximum DC resistance of 264 mOhm, housed in a compact nonstandard 1212 (3.0 x 3.0 x 1.5 mm) surface-mount case. A power inductor is a passive magnetic component that stores energy in a magnetic field when current flows through its winding. Within the power-management hierarchy, it sits at the component level of a DC-DC converter stage: a voltage regulator (power management IC) uses the inductor, together with switching MOSFETs and output capacitors, to convert one DC voltage to another. Power inductors are characterized by inductance, saturation and rated current, DC resistance (DCR), and the degree of magnetic shielding. The NRS3015T100M belongs to Taiyo Yuden's NR/NRS series of SMD power inductors. Its semi-shielded drum-core construction confines most of the magnetic flux within the component body, reducing coupling into neighboring circuits compared with fully open drum-core designs while avoiding the higher DCR of fully shielded types. The M suffix denotes a 20% inductance tolerance, and the part is wound with copper wire on a magnetic drum core to achieve 10 uH in a small footprint. Key engineering figures are the 700 mA rated current, 264 mOhm maximum DCR (which sets the DC copper loss, roughly 0.13 W at rated current - estimate based on I2R using 0.7 A squared times 0.264 Ohm), and the 3.0 x 3.0 mm footprint with a low 1.5 mm profile. These figures suit buck and boost converter outputs in the few-hundred-milliamp class. Typical applications include point-of-load buck converter output filters in portable and battery-powered devices, LED driver rails, DC-DC modules for IoT and wearables, and general-purpose power supply decoupling and ripple filtering. When designing with this inductor, verify that the peak switching current including ripple remains below the saturation rating of the part, and keep high di/dt loop areas small by placing the inductor directly adjacent to the switching regulator pins. This page synthesizes verified distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
NRS3015T1R0M - 1uH 2.1A Semi-Shielded Power Inductor | Taiyo Yuden
The Taiyo Yuden NRS3015T1R0M is a 1 uH semi-shielded drum core, wirewound SMD power inductor with a maximum current rating of approximately 2.1 A and a maximum DC resistance of 36 mOhm, housed in a compact 3015 (3.0 x 3.0 x 1.5 mm) nonstandard chip package. An SMD power inductor is a passive energy-storage component that stores energy in a magnetic field and releases it to smooth current in switching power converters. Within the component hierarchy it belongs to the fixed inductor family, itself a subcategory of inductors, coils and chokes under passive components. Power inductors are core building blocks of DC-DC converters, where inductance value, saturation current and DCR directly determine converter efficiency, ripple and transient response. Key features of the NRS3015 series include a semi-shielded drum core wirewound construction that reduces magnetic flux leakage compared with fully open drum designs while retaining wirewound current capability, a low 36 mOhm maximum DCR that minimizes conduction losses, and metallization on the ferrite core which provides excellent shock resistance and damage-free durability. The compact 3015 footprint supports dense converter layouts in portable equipment. The wirewound construction on a metallized ferrite core yields high saturation current headroom and stable inductance under bias, making the part suitable for buck and boost converter output and energy-transfer roles. The semi-shielded structure lowers coupling to neighboring inductors in multi-phase or multi-rail designs relative to unshielded equivalents. Typical applications include point-of-load DC-DC converters in mobile phones, tablet and laptop PCs, AV equipment, OA and office equipment, home electric appliances, and general information and communication equipment. A key design consideration: verify saturation current at your worst-case peak load and ambient temperature, since datasheet ratings are measured under reference conditions and real performance varies with environment.

PFL2015-682ME - 6.8µH Shielded Power Inductor | Coilcraft
The Coilcraft PFL2015-682ME is a 6.8 µH molded shielded surface-mount power inductor rated for 680 mA saturation current and 400 mOhms DC resistance (DCR), housed in a compact 2.0×2.0×1.5 mm composite-core package. It belongs to the PFL2015 family of ultra-small molded power inductors that combine small size, high efficiency, and a competitive price point for switching converter output filtering. A power inductor is a passive energy-storage element that stores energy in a magnetic field when current flows through its windings, then releases that energy to maintain continuous conduction in switching DC-DC converters. The molded shielded construction places the winding inside a composite magnetic core and a magnetically-shielded housing, suppressing stray flux that would otherwise couple into adjacent traces or components. PFL2015-682ME sits in the inductor taxonomy as: molded power inductor → shielded power inductor → SMD power inductor → passive component. Key features include a soft-saturation characteristic that allows brief peaks above the saturation rating without hard inductor roll-off, an AEC-Q200 qualification supporting automotive reliability requirements, a low DCR of 400 mOhms that minimizes I²R conduction loss, and a shielded package that reduces EMI in dense PCB layouts. The 6.8 µH inductance is set by the coil geometry using a composite core material, providing repeatable performance across the −40 °C to +125 °C operating temperature range. Typical applications include DC-DC buck and boost converter output filters, point-of-load (POL) regulators, battery-powered portable device power management, automotive infotainment and ADAS power rails, and LED driver output stages. The 680 mA current rating supports mid-current rails such as 3.3 V or 5 V core supplies and most sub-amp loads. Designers should derate saturation current at elevated ambient temperature (typically to 80% at 85 °C) and place the inductor adjacent to the switching node to minimize the AC loop area, which improves efficiency and reduces radiated EMI. Verify that the saturation rating covers the converter peak inductor current, not just the average load current. This page consolidates distributor pricing, AEC-Q200 compliance context, drop-in PFL family alternatives, and application notes that are not present in the Coilcraft catalog entry.
