CRCW20102K70FKEFHP Übersicht
A thick film chip resistor is a passive component in which a resistive paste (typically ruthenium oxide in a glass binder) is screen-printed onto a high-purity alumina (Al<sub>2</sub>O<sub>3</sub>) ceramic substrate, then fired at high temperature. End-cap terminations plated with nickel and tin enable standard reflow soldering. Thick film resistors sit in the broader passive-component taxonomy of resistor → fixed resistor → chip resistor → thick film → surface-mount device (SMD), and they remain the workhorse of consumer, industrial, and automotive electronics because they balance cost, stability, and pulse capability.
Key features of this part include an absolute resistance of 2.7 kΩ, F (±1%) tolerance, a 1 W continuous power rating at 70 °C, a 100 ppm/K temperature coefficient (TCR), and a maximum working voltage of 400 V. It is qualified to the AEC-Q200 automotive reliability standard and is designed as a pulse-withstanding variant (the "HP" suffix), making it tolerant to single-pulse and repetitive surge loads such as inrush, ESD, and snubber discharge events.
The CRCW-HP series uses a special thick-film paste formulation and an enlarged termination geometry to absorb short-duration energy without film cracking or resistance drift. The 2010 case size provides a thermal mass and copper pad area that keep the resistor within rated temperature rise even when dissipating 1 W on a standard FR-4 test board.
Typical applications include automotive ECU power conditioning, motor driver snubbers and gate-pull circuits, inrush current limiting on 12 V/24 V/48 V buses, industrial PLC analog I/O filtering, and general-purpose DC-DC converter feedback networks where high pulse energy absorption is required.
When designing with this device, derate heats of each pulse against the datasheet single-pulse curve and confirm that the PCB land pattern uses 2 oz copper with thermal relief to the plane — undersized pads cause the hot-spot to exceed 200 °C and shorten life.

Typische Anwendungen
CRCW20102K70FKEFHP ist geeignet für 6 Anwendungs: Automotive ECU Power Conditioning, DC-DC Converter Feedback Divider, Motor Driver Snubber and Gate Drive, Industrial PLC Analog Input Filtering, Inrush Current Limiting on 48 V Mild-Hybrid Bus, General-Purpose Pull-Up / Pull-Down Resistor.
Automotive ECU Power Conditioning
The CRCW20102K70FKEFHP is well suited to 12 V/24 V automotive ECU power conditioning networks where it serves as a pull-up on signal lines, gate-bias resistor on low-side switches, or filter element on 5 V analog rails. Its AEC-Q200 qualification and -55 °C to +155 °C operating range satisfy under-hood and body-module requirements. The 1 W continuous rating and 400 V maximum working voltage provide substantial headroom for load-dump transients on the 12 V bus, and the 2.7 kΩ value is the standard value used to bias optocoupler LED cathodes and low-side N-channel MOSFET drivers in BCM and HVAC control modules. Compared to commercial-grade thick film resistors, the HP pulse-withstanding series absorbs the repetitive inrush from relay coil flyback diodes without film cracking or drift.
Empfohlen
DC-DC Converter Feedback Divider
In isolated and non-isolated DC-DC converter feedback networks, the CRCW20102K70FKEFHP serves as the upper or lower divider resistor, setting the converter output voltage. Its ±1% tolerance minimizes trim overhead, while ±100 ppm/°C TCR over -55 °C to +155 °C provides stable regulation across industrial temperature ranges. The 1 W power rating exceeds the dissipation in 12 V-to-3.3 V/5 V/12 V buck converter divider branches by 2×-5× margin, and the 400 V maximum working voltage tolerates the rectified 380 V bus in PFC front-end converters. Engineers should size the parallel resistor so Vbias stays below 5 V to avoid leakage-induced error.
Empfohlen
Motor Driver Snubber and Gate Drive
Brushless DC (BLDC) and stepper motor driver stages generate large dV/dt transients on the phase and gate nodes that need snubber and gate-pull resistors with high pulse capability. The CRCW20102K70FKEFHP's HP-series pulse-withstanding rating absorbs the repetitive discharge from gate-driver RC networks and from flyback clamps across low-side MOSFET drains. The 2.7 kΩ value is standard for IGBT/MOSFET gate-pull circuits on 24 V to 600 V class drivers, where the 400 V rating and 1 W continuous rating of the 100 N are sufficient. AEC-Q200 qualification makes it suitable for electric power steering (EPS), electric water pump, and HVAC blower motor applications.
Empfohlen
Industrial PLC Analog Input Filtering
Industrial PLC analog input modules require RC low-pass filters on 4-20 mA, 0-10 V, RTD, and thermocouple inputs to reject EMI from motor inverters and relay switching. The CRCW20102K70FKEFHP serves as the series resistor in such filter networks, where its 2.7 kΩ value combined with 100 nF capacitor gives a 590 Hz cutoff suitable for slow analog signals. Its wide -55 °C to +155 °C operating range supports outdoor cabinet and factory-floor applications, and its 1 W rating handles the over-voltage transients from miswired field wiring. The HP-series pulse-withstanding capability absorbs the ESD events from cable handling during commissioning.
Empfohlen
Inrush Current Limiting on 48 V Mild-Hybrid Bus
48 V mild-hybrid automotive systems and industrial 48 V bus converters use paralleled decoupling capacitors at the input of downstream buck converters, requiring inrush limiting during hot-plug events. The CRCW20102K70FKEFHP's 2.7 kΩ value, 1 W continuous rating, and 400 V working voltage tolerate the 48 V nominal / 60 V transient rail and absorb the repetitive inrush pulse during each system wake-up. The HP-series pulse-withstanding rating prevents drift or failure from the repetitive pulse train, and AEC-Q200 qualification meets the mild-hybrid reliability requirements. Compared to wirewound alternatives the SMD 100 N-dimensional 2010 footprint saves 70% PCB area.
Empfohlen
General-Purpose Pull-Up / Pull-Down Resistor
Beyond the specific applications above, the CRCW20102K70FKEFHP is widely used as a generic pull-up or pull-down on digital logic lines, I2C/SPI bus lines, and reset/strap pins. The 2.7 kΩ value is within the standard range (1 kΩ to 10 kΩ) used to bias logic lines against leakage currents while providing robust drive strength. The 1 W rating, 400 V working voltage, and ±1% tolerance make it a strong general-purpose choice across consumer electronics and white goods designs where AEC-Q200 is not required but high reliability and pulse capability are still desirable.

Wichtigste Unterscheidungsmerkmale
- HP-series pulse-withstanding rating (vs. CRCW20102K70FKEF (standard CRCW2010))
- Higher continuous power rating (1 W vs 0.75 W) (vs. ERJ-12SF2701U (Panasonic))
- Higher maximum working voltage (400 V vs 200 V) (vs. RC2010FK-072K7L (Yageo))
Designhinweise
Estimated: At full 1 W dissipation on a standard 1 oz copper FR-4 test board with 100 mm² pad, junction temperature rise is approximately 70-90 °C above ambient; on a 2 oz copper pad with thermal relief the rise drops to ~50 °C. For continuous operation above 0.5 W, ensure at least 100 mm² of 2 oz copper per termination. The HP series does NOT change thermal resistance versus standard CRCW2010 — the HP suffix only improves pulse energy capability, not steady-state thermal rating.
Use Vishay-recommended land pattern (per datasheet): pad size 2.5 mm × 1.25 mm with 0.5 mm gap. Traces should be 2 oz copper with thermal relief to the plane. Avoid placing the resistor near tall components that shadow airflow; the HP series benefits from convective cooling during high pulse events.
Do not exceed the 1 W continuous rating or 400 V maximum working voltage — both are independent limits, and exceeding either causes permanent resistance shift or open-circuit failure. In pulse applications, calculate pulse energy E = V²·t/R and check against the single-pulse curve; do NOT assume the HP rating allows continuous over-power. For divider networks, ensure the parallel resistor keeps total power dissipation below 50% of rated to prevent drift over life.
Place the resistor close to the IC pin or load to minimize parasitic inductance in pulse applications. For high-frequency circuits (>10 MHz) the 2010 case introduces ~1 nH; for divider networks this is negligible, but for snubber circuits across switching nodes the inductance can resonate with capacitance and cause voltage overshoot. Add a small ferrite bead in series if overshoot exceeds the rating.

RoHS compliant via e3 matte-tin finish per Vishay datasheet. AEC-Q200 qualified (automotive passive standard, not AEC-Q100 which applies to active ICs). Lead-free and REACH compliant per Vishay product declaration. Conflict-minerals declaration available on Vishay website.
