ERJ2RKF1582X Overview
A thick-film chip resistor is a passive surface-mount component whose resistive element is a ruthenium-oxide (RuO2) or metal-glaze film screen-printed onto a ceramic alumina (Al2O3) substrate, then capped with three plated-nickel electrode layers for solderability. The ERJ-2RK family uses Panasonic's metal-glaze thick-film element to deliver ±1% initial tolerance and a Temperature Coefficient of Resistance (TCR) that is suitable for general-purpose analog, signal-conditioning, and pull-up/pull-down functions within the broader passive-component taxonomy of fixed resistors → chip resistors → thick-film resistors → surface-mount devices.
Key specifications include a resistance value of 15.8 kOhm with ±1% tolerance, a power rating of 0.1 W at 70 °C, a maximum working voltage of 50 V, and an operating temperature range of -55 °C to +155 °C. The device is RoHS-compliant (Pb-free terminations) and qualified to AEC-Q200, allowing it to be used in automotive under-hood and cabin electronics where reliability under thermal and mechanical stress is mandatory. Its 0402 land pattern is universally accepted by automated pick-and-place assembly lines.
Typical applications for the ERJ2RKF1582X include precision voltage dividers in sensor-signal conditioning circuits, op-amp gain-setting resistors, current-sense shunts in low-power monitoring loops, ADC reference ladder networks, and pull-up / pull-down biasing in digital logic. The AEC-Q200 qualification makes it particularly suitable for body-control modules, instrument clusters, ADAS sensor PCBs, and infotainment power management where a 0402 size, 1% tolerance, and 15.8 kΩ value align with common E96 reference designs. The 0.1 W rating is sufficient for signal-level currents where self-heating must remain minimal.
When designing with this part, verify that the operating voltage across the resistor never exceeds 50 V, and derate power at temperatures above 70 °C per Panasonic's standard resistor derating curve. For 1% tolerance resistors, attention to PCB solder-pad cleanliness and reflow-profile conformance (peak ≤260 °C per JEDEC J-STD-020) preserves long-term stability. The AEC-Q200 stress-test pedigree (thermal-shock, biased-humidity, and mechanical-shock qualifications) supports deployment in safety-relevant automotive subsystems without additional up-screening.

Typical Applications
ERJ2RKF1582X is suitable for 6 applications: Automotive Sensor Signal Conditioning, Op-Amp Gain-Setting Resistor, ADC Reference Voltage Divider, Digital Logic Pull-Up / Pull-Down Bias, Current-Limit / Soft-Start Circuit, Industrial Process Control Interface.
Automotive Sensor Signal Conditioning
The ERJ2RKF1582X is well-suited to automotive sensor signal-conditioning front-ends, particularly in body-control modules and ADAS sensor PCBs. The 15.8 kΩ ±1% tolerance supports accurate voltage-divider biasing for analog-front-end op-amp gain-setting networks that read temperature, pressure, or position sensors. Its AEC-Q200 qualification and 0402 footprint enable high-density layouts under the hood, while the 0.1 W rating at 70 °C handles the continuous bias currents typical of these circuits without excessive self-heating. The 50 V maximum rating also provides headroom for transient automotive load-dump events on supply rails.
Recommended
Op-Amp Gain-Setting Resistor
The ERJ2RKF1582X serves as a precision gain-setting or feedback resistor in op-amp circuits such as non-inverting amplifiers, inverting amplifiers, and active filters. The 15.8 kΩ ±1% tolerance, paired with a matching input resistor, enables accurate closed-loop gain with low offset error. Its ±100 ppm/°C TCR maintains calibration over the -55 °C to +155 °C automotive temperature range, which is critical for instrumentation amplifiers in test equipment and medical monitoring devices. The 0402 footprint allows compact multi-channel analog front-ends.
Recommended
ADC Reference Voltage Divider
In ADC reference and bias-divider networks, the ERJ2RKF1582X provides the precision tap point that sets the full-scale reference voltage for successive-approximation or delta-sigma converters. The 15.8 kΩ ±1% tolerance directly determines the ADC reference accuracy, while the ±100 ppm/°C TCR minimizes gain drift over temperature. The 0402 footprint supports high-density mixed-signal PCB layouts where digital and analog grounds are isolated. The 50 V maximum working voltage covers the supply ranges of 5 V, 12 V, and 24 V analog rails.
Recommended
Digital Logic Pull-Up / Pull-Down Bias
The ERJ2RKF1582X is commonly used as a pull-up or pull-down bias resistor on digital logic lines such as I2C, SPI chip-select, GPIO enable pins, and reset lines. The 15.8 kΩ value strikes a balance between low quiescent current consumption and robust noise immunity for typical 3.3 V and 5 V logic levels. The 0402 surface-mount package is well-suited to high-density microcontroller-based designs, and AEC-Q200 qualification allows deployment in automotive ECUs and industrial control systems. Its 0.1 W rating easily handles the small bias currents drawn by these functions.
Recommended
Current-Limit / Soft-Start Circuit
The ERJ2RKF1582X functions as a current-sense or current-limit set-point resistor for low-power supply and soft-start networks, including USB ports, LED drivers, and low-side current-sense paths. The 15.8 kΩ ±1% value sets the trip threshold or reference voltage for current-limit comparators with predictable accuracy. Its 0402 footprint supports the compact power-management layouts common in industrial controllers, while the 0.1 W rating covers the bias currents of typical current-sense amplifiers. The AEC-Q200 rating enables automotive body-electronics deployment.
Recommended
Industrial Process Control Interface
In industrial process-control and factory-automation interfaces, the ERJ2RKF1582X supports 4-20 mA loop interfaces, transducer signal paths, and isolated analog front-ends. The 15.8 kΩ ±1% tolerance enables accurate loop-current sensing when used in current-sense or scaling networks, while the wide operating temperature range (-55 °C to +155 °C) ensures reliable operation in factory-floor and outdoor industrial environments. The 0402 package is compatible with high-density PLC and HMI PCB designs where board space is constrained. AEC-Q200 qualification provides additional reliability margin for mission-critical industrial subsystems.

Key Differentiators
- AEC-Q200 automotive qualification (vs RC0402FR-0715K8L (Yageo))
- Higher power rating (0.1 W vs 0.063 W) (vs CRCW040215K8FKED (Vishay))
- Same ERJ-2RKF family consistency (vs ERJ-2RKF1502X (15 kΩ))
Design Notes
Estimated: At maximum rated voltage of 50 V across the 15.8 kΩ resistor, the continuous dissipation is P = V²/R = 50²/15800 ≈ 0.158 W, which exceeds the 0.1 W rating. For high-voltage divider applications, verify that operating voltage × steady-state current ≤ 0.1 W, or derate the supply voltage. For typical 5 V or 12 V signal-level circuits, the ERJ2RKF1582X operates well within its power rating.
Power derating must be applied above 70 °C ambient per the ERJ-2RK datasheet curve. Estimated: At 125 °C ambient, the allowable dissipation drops to approximately 0.1 W × (155-125)/(155-70) ≈ 0.035 W. For under-hood automotive layouts where ambient temperature can exceed 100 °C, verify that actual dissipation remains within the derated envelope. The 0402 package has limited thermal mass and relies on PCB copper pour for heat spreading.
Use the standard 0402 land pattern with pad dimensions of approximately 0.5 mm × 0.5 mm and 0.2 mm gap per IPC-7351. Solder paste stencil aperture of 0.45 mm × 0.45 mm with 0.1-0.125 mm thickness supports reliable reflow. Peak reflow temperature per JEDEC J-STD-020 is 260 °C for Pb-free profiles. Avoid placing the ERJ2RKF1582X adjacent to large heat-dissipating components such as power MOSFETs to prevent thermal-shock solder-joint fatigue.
Do not exceed the 50 V maximum working voltage even momentarily, as transient overvoltage can cause resistor failure or resistance shift. Verify that the operating voltage × possible fault current does not exceed the resistor's pulse-withstanding capability for the application's pulse duration. For ESD-sensitive signal paths, additional TVS protection or series resistance may be required; the ERJ2RKF1582X is not rated as an ESD-protective component.
