ERJ3EKF9100V Présentation
A thick film chip resistor is a passive component in which a resistive ceramic-metal (cermet) paste is screen-printed onto an alumina ceramic substrate, then fired at high temperature to form the resistive element. In the resistor taxonomy, it sits below wirewound and foil resistors for precision but above carbon-film for cost-effectiveness. As an SMD component in the 0603 family (1.6 mm × 0.8 mm), the ERJ3EKF9100V belongs to the broader surface-mount chip resistor hierarchy and is used wherever compact, reflow-solderable, low-cost resistance is required.
Key specifications include 910Ω resistance at ±1% tolerance, a power rating of 0.1W at 70°C, an operating temperature range of -55°C to +155°C, a maximum working voltage of 75V, and a temperature coefficient of resistance (TCR) of ±100 ppm/°C. The 0603 package provides a stable land pattern that is compatible with all mainstream reflow and wave-solder processes, and its standardized dimensions ensure drop-in compatibility with Panasonic's entire ERJ-3E series.
The ERJ3EKF9100V is qualified to the Automotive Electronics Council AEC-Q200 stress-test standard, which subjects parts to thermal shock, moisture resistance, solderability, and mechanical shock tests. This makes it suitable not only for consumer electronics but also for under-hood automotive modules, ADAS sensor PCBs, and industrial control boards.
Typical applications include automotive ECU signal conditioning, CAN bus termination, sensor pull-up/pull-down biasing, precision voltage divider references, and general PCB I/O clamping. Its 1% tolerance is sufficient for most analog signal-conditioning circuits while remaining affordable for high-volume consumer products.
When designing with this part, ensure the operating voltage does not exceed 75V and that the derated power curve at temperatures above 70°C is respected. For 910Ω applications requiring higher precision, consider the ERJ-3EKF (1%) versus the ERJ-3GE (5%) - line the value of tolerance for your design budget.

Applications typiques
ERJ3EKF9100V convient pour 6 applications: Automotive ECU Signal Conditioning, CAN Bus Termination Pull-Up, Precision Voltage Divider Reference, Sensor Pull-Up/Pull-Down Biasing, Industrial Control Board I/O Clamping, Medical Monitoring Device Front-End.
Automotive ECU Signal Conditioning
The ERJ3EKF9100V's 910Ω ±1% tolerance and AEC-Q200 qualification make it ideal for automotive ECU signal conditioning networks. In powertrain and body control modules, it sets bias currents for sensor interfaces, including thermistor dividers, Hall-sensor pull-ups, and 0-5V analog signal scaling. The 100 ppm/°C TCR keeps calibration drift under 0.5% across -40°C to +125°C automotive temperature ranges, and its 75V working voltage comfortably exceeds 12V/24V automotive bus transients. The 0603 footprint supports compact ECU layouts. Real-world placement: between the ECU MCU ADC input pin and a 5V reference, scaling a 0-5V sensor output to 0-3.3V. The 1% tolerance ensures end-of-line calibration passes without per-unit trimming. Compared to a 5% resistor, the F-series reduces gain error by 80%, directly improving sensor reading accuracy for emissions, ABS, and ADAS subsystems.

CAN Bus Termination Pull-Up
In CAN and CAN-FD bus networks, the ERJ3EKF9100V can serve as a 910Ω pull-up biasing element on the CANH/CANL differential pair to set recessive-state logic levels. While standard CAN termination uses 120Ω across the bus, supplementary pull-up/pull-down biasing at transceiver inputs often requires precise values in the 500Ω-1kΩ range. The 1% tolerance ensures symmetric high/low thresholds across the bus, minimizing bit-error-rate variation node-to-node. AEC-Q200 qualification supports under-hood and chassis-mounted CAN nodes. The 0.1W rating handles the small DC bias current continuously without thermal stress. Compared to discrete resistor networks, a single 0603 chip reduces BOM count by 60% and saves ~5mm² of PCB area, critical for densely-packed automotive gateway modules where space is at a premium and qualification traceability is mandatory.

Precision Voltage Divider Reference
The ERJ3EKF9100V is well-matched for the upper or lower leg of a precision voltage divider in ADC reference scaling and DAC output feedback networks. With ±1% tolerance and 100 ppm/°C TCR, it provides stable divider ratios across -40°C to +125°C operating ranges without requiring expensive 0.1% thin-film parts. In a 5V-to-3.3V divider, pairing it with a 600Ω lower resistor produces a 3.0V reference for a 12-bit ADC, achieving effective INL of ±0.5 LSB after calibration. The 0603 0.1W rating handles the divider's continuous ~3mA quiescent current with negligible self-heating. AEC-Q200 qualification extends precision divider usage into safety-relevant ADAS ECUs, electronic power steering, and battery management modules where voltage reference accuracy directly impacts torque control or state-of-charge estimation accuracy in production vehicles.
Recommandé
Sensor Pull-Up/Pull-Down Biasing
For discrete analog sensors like NTC thermistors, photodiodes, and mechanical switches, the ERJ3EKF9100V provides accurate pull-up or pull-down biasing at 910Ω. In an NTC thermistor divider, the 910Ω upper resistor paired with a 10kΩ@25°C thermistor produces a temperature-dependent voltage with good linearity over 0-70°C, where the 1% initial accuracy dominates over the thermistor's ±2% spec. AEC-Q200 qualification makes it suitable for under-hood temperature, pressure, and position sensors. The 0603 size supports high-density sensor PCBs, and the 75V working voltage comfortably exceeds automotive load-dump transients. Compared to a 5% resistor, the 1% tolerance reduces sensor calibration error by a factor of 4, critical for OEM-spec emission sensors and battery-pack temperature monitors where out-of-spec readings trigger warranty events.

Industrial Control Board I/O Clamping
In industrial PLCs, motor controllers, and 24V I/O modules, the ERJ3EKF9100V serves as an input current-limiting or clamping resistor on digital inputs. With a 24V industrial input voltage, the 910Ω value limits input current to ~25mA when combined with a 5V zener clamp, protecting downstream MCU GPIO pins from industrial transients. The 0.1W rating handles continuous 25mA (P = I²R ≈ 0.006W) with negligible self-heating, and the 75V working voltage exceeds 24V nominal plus transient tolerance. AEC-Q200 qualification, although not mandatory for industrial, provides extra margin for factory-floor environments with high EMI and ESD exposure. The 0603 footprint allows placement directly at the I/O connector, minimizing trace inductance and improving surge immunity on long cable runs.
Recommandé
Medical Monitoring Device Front-End
In medical monitoring equipment such as patient monitors, pulse oximeters, and ECG front-ends, the ERJ3EKF9100V provides reliable current-limiting or voltage-divider biasing in analog signal paths. The 1% tolerance ensures accurate gain setting in instrumentation amplifier feedback networks, while the 100 ppm/°C TCR keeps gain drift under 0.1% across body-temperature operating ranges. AEC-Q200 qualification provides extra reliability margin in battery-powered portable medical devices subject to mechanical stress. The 0603 footprint supports miniaturized wearable designs, and its lead-free, halogen-free construction meets medical device environmental compliance requirements. Compared to cheaper 5% resistors, the 1% tolerance eliminates the need for per-unit gain calibration in low-volume medical device production, reducing manufacturing test time and BOM cost simultaneously.

Notes de conception
Estimated: At maximum rated voltage of 75V across 910Ω, the steady-state current is I = V/R = 75/910 ≈ 82 mA, and power P = V²/R = 5625/910 ≈ 6.18 W, which vastly exceeds the 0.1W rating. The 75V limit is set by insulation breakdown, not continuous operating power. For continuous operation, limit voltage to V_max_continuous = sqrt(P_max × R) = sqrt(0.1 × 910) ≈ 9.5V to stay within rated dissipation. In typical 3.3V/5V logic-level circuits, this limit is never reached.
Estimated: At rated 0.1W dissipation in still air, a standard 0603 resistor has theta_JA around 400 C/W, giving a junction temperature rise of ~40°C above 25°C ambient. Power derating begins at 70°C, with rated power decreasing linearly to zero at 155°C. For hot-spot applications near heat sources (e.g., adjacent to a motor driver IC), verify with a thermal probe. Mounting on standard 1-oz copper land pattern provides adequate heat spreading; no thermal relief is required at 0.1W.
Use the standard IPC-7351 nominal 0603 land pattern: 0.95 mm × 0.80 mm pads with 0.80 mm spacing (pad-to-pad). Both terminals are equivalent; the resistor is non-polar. Avoid placing the 0603 chip in line with high-vibration flex PCB areas - the solder joints are the weakest link. For double-sided assembly, ensure the resistor is on the side opposite the primary bending axis. Use no-clean SAC305 lead-free solder with 245°C peak reflow per J-STD-020.
Common pitfalls: (1) Do not exceed 75V across the resistor even momentarily, or insulation breakdown may occur. (2) Do not confuse the '9100' resistance code with '910' - it is 910Ω × 10^0 = 910Ω, NOT 9100Ω. (3) For precision analog circuits, derate by 50% (use only 0.05W) to keep self-heating TCR errors below 50 ppm. (4) The F-suffix (±1%) parts are AEC-Q200 qualified, but the G-suffix (±2%) and J-suffix (±5%) parts in the same series are consumer-grade only - do not substitute in automotive designs.
