CRCW0402100KFKED 概要
A chip resistor (also called a surface-mount resistor or SMD resistor) is a passive two-terminal component that provides a fixed value of electrical resistance in a circuit. Chip resistors are the most common component type on a printed circuit board, typically outnumbering all other parts by 10:1 or more. Within the resistor taxonomy, the CRCW0402100KFKED belongs to the thick-film chip resistor family, where a glass-frit-bonded resistive paste is screen-printed onto a ceramic substrate and laser- or laser-trimmed to the target value. Thick-film technology offers an excellent balance of cost, stability, and power handling for general-purpose applications.
Key specifications of the CRCW0402100KFKED include 100 kOhm resistance with ±1% tolerance (F-code), a 50 V maximum working voltage, a 0.063 W rated power dissipation at 70 °C (derated linearly to zero at 155 °C), and a temperature coefficient of resistance (TCR) of ±100 ppm/°C. The 0402 footprint measures 1.0 mm × 0.5 mm (imperial 0402), making it one of the smallest standard EIA sizes and ideal for high-density consumer, industrial, and automotive boards. Solderability is qualified to JEDEC J-STD-020 reflow profiles at 260 °C peak.
Architecturally, the device uses a single rectangular resistive element with wrap-around terminations that provide reliable solder fillets on standard land patterns. The protective overcoat (glaze) isolates the resistive film from environmental contamination, contributing to the part's moisture sensitivity classification of MSL-1. Compared to thin-film alternatives (e.g., RN73 series), thick-film resistors like CRCW0402100KFKED trade slightly higher TCR (±100 ppm/°C vs. ±10 to ±25 ppm/°C) for substantially lower cost and broader availability at standard E96 values.
Typical applications for the CRCW0402100KFKED include pull-up and pull-down resistors in digital logic, bias networks for transistor and op-amp circuits, voltage dividers in sensor signal conditioning, RC filter elements in audio and communication circuits, current-setting resistors for LED drivers and DC-DC converters, and termination resistors on high-speed signal lines. Its AEC-Q200 qualification makes it well-suited for body electronics, infotainment, instrument clusters, and under-hood control modules where automotive stress compliance is required.
When designing with the CRCW0402100KFKED, derate the 0.063 W power rating above 70 °C ambient using the linear derating curve (zero power at 155 °C). For high-impedance nodes in noise-sensitive analog circuits, verify the parallel leakage paths on the PCB to preserve the 100 kOhm effective resistance. Standard EIA 0402 land patterns (per IPC-7351) apply; however, confirm pad geometry to avoid tombstoning during reflow.

主な用途
CRCW0402100KFKED の用途: 6 件s: Digital Logic Pull-Up / Pull-Down Resistors, Voltage Divider for Sensor Signal Conditioning, LED Driver Current-Setting Resistor, RC Filter for Audio and Communication Circuits, Termination Resistor on High-Speed Signal Lines, Automotive Body and Infotainment Electronics.
Digital Logic Pull-Up / Pull-Down Resistors
The CRCW0402100KFKED's 100 kOhm resistance makes it ideal for I2C, SPI, and GPIO pull-up or pull-down biasing on digital logic lines, where the weak 100 kOhm value minimizes quiescent current while still providing a defined logic level when no driver is active. Placed between a signal line and VCC or GND, the resistor establishes the default state and prevents floating inputs. Its ±1% tolerance ensures predictable logic thresholds, and the 0.063 W rating far exceeds the static dissipation (typically <<1 mW) of bias applications. AEC-Q200 qualification allows use in automotive ECUs and body controllers.
おすすめ
Voltage Divider for Sensor Signal Conditioning
In battery monitoring, thermistor interfaces, and ADC input scaling, the CRCW0402100KFKED forms the upper or lower half of a resistive divider that scales a high-voltage sensor signal into the ADC input range. With 100 kOhm and ±1% tolerance, the divider ratio is precisely defined, contributing less than 0.5% error to the measurement. The 50 V working voltage comfortably handles 12 V or 24 V automotive bus measurements. Its 0402 footprint preserves board space in compact sensor modules and battery management systems, while AEC-Q200 stress compliance supports under-hood and chassis-mounted sensor applications.
おすすめ
LED Driver Current-Setting Resistor
The CRCW0402100KFKED is well-suited as a current-setting resistor in low-current LED indicator circuits, where 100 kOhm combined with a low-current LED (e.g., 2 mA typical) limits the LED current to a safe value from a 3.3 V or 5 V logic rail. The 0.063 W power rating easily handles the <10 mW dissipation typical of indicator LEDs. The 0402 SMD package supports high-density front-panel designs and miniature indicator modules, while the AEC-Q200 qualification enables dashboard and interior lighting applications in automotive human-machine interfaces.
おすすめ
RC Filter for Audio and Communication Circuits
In low-pass or high-pass RC filter networks, the CRCW0402100KFKED pairs with a capacitor (e.g., 1 nF to 1 uF) to set the cutoff frequency from 1.6 Hz to 160 Hz for audio frequency shaping, EMI suppression, or anti-aliasing before an ADC. The ±1% tolerance ensures the -3 dB corner frequency is well-defined, and the ±100 ppm/°C TCR is adequate for non-precision audio paths. Its 0402 package fits into dense mixed-signal layouts where op-amps, DACs, and microcontrollers share tight PCB real estate.
おすすめ
Termination Resistor on High-Speed Signal Lines
While not a controlled-impedance transmission-line terminator, the CRCW0402100KFKED can serve as a weak pull-down or pull-up on high-speed logic lines (LVCMOS, LVDS auxiliary biasing) where 100 kOhm prevents charge accumulation without loading the driver. Its 0402 package introduces minimal parasitic inductance (<1 nH) compared to larger packages, preserving signal integrity up to several hundred MHz for auxiliary side-band signals. The 50 V working voltage provides ample margin for any transient overshoot on 3.3 V or 5 V logic rails.
おすすめ
Automotive Body and Infotainment Electronics
The CRCW0402100KFKED's AEC-Q200 qualification and -55 °C to +155 °C operating range make it directly suitable for automotive body control modules, instrument clusters, infotainment head units, and HVAC control panels. Designers use 100 kOhm ±1% values for switch contact debouncing, key-fob interface biasing, and backlight driver current programming. The 0402 footprint supports the high component density of modern automotive PCBs, while the e3-series Pb-free plating meets global automotive OEM environmental substance restrictions.

設計ノート
The CRCW0402100KFKED is rated at 0.063 W at 70 °C ambient and must be linearly derated to zero power at 155 °C. Use the formula P_max(T) = 0.063 W × (155 - T_ambient)/85 for any ambient above 70 °C. In high-temperature automotive under-hood environments, verify the actual PCB copper area under the part maintains the specified thermal resistance. Exceeding rated power causes resistance shift, hot spots, and eventual open-circuit failure.
Use the IPC-7351 nominal 0402 land pattern: two 0.50 mm wide pads on 0.80 mm pitch, each 0.40 mm long, with a 0.40 mm solder mask expansion. Smaller pads risk tombstoning during reflow; larger pads risk solder bridging. Place the part on a solid ground or signal pour to improve thermal dissipation and reduce DC-bias effects. Keep high-current traces away from the resistor body to avoid thermomechanical stress during temperature cycling.
At 100 kOhm, the resistor presents high impedance to DC, but the 0402 package's small pad area and finite surface insulation resistance (typically >10 GOhm) can be degraded by flux residue, conformal coating pinholes, or humidity. Always clean flux residues after soldering and avoid placing the part adjacent to high-voltage (>50 V) traces where surface arcing could occur. Confirm the actual resistance on the production PCB, as parallel leakage paths can reduce the effective impedance below the specified 100 kOhm in low-noise analog circuits.
