EVER OHMS CRH2512F3R90E04S 2512 Chip Resistor - 3.9Ω Resistance, 2W Power Rating, ±1% Tolerance High Power Thick Film SMD Resistor
CRH2512F3R90E04S is a high-power thick film chip resistor from EVER OHMS (天二科技), featuring a 2512 package, 3.9Ω (3.9R) resistance, ±1% tolerance, 2W power rating, and ±400PPM temperature coefficient. It is designed for medium-power current limiting, voltage division, and load applications in industrial and automotive environments.
???? Note: This part is a high-power thick film chip resistor, not an alloy current-sense resistor. For mΩ-level precision current sensing (BMS, fast charging, motor drives), refer to EVER OHMS MA/MN alloy series (e.g., MA2512 0.012R–0.05R / 2W, ±50PPM). The 2512 3.9R 2W resistor is best suited for current limiting, voltage dividing, and bleeder/load circuits.

With a rated current of ~0.716A (I=√(P/R)=√(2/3.9)), this 2512 3.9R 2W resistor fits medium-low resistance, medium-power scenarios:
- Power management: Current limiting and voltage dividing in SMPS and DC-DC converters
- Industrial control: Buffering and bleeder circuits in VFDs and servo drives
- Automotive electronics: ECU, BMS auxiliary circuits, EPS control modules
- Consumer electronics: Fast chargers, power tools, drone power stages
- Home appliances & industrial switches: Sensing and drive circuits in air conditioners, dehumidifiers, and industrial isolation switches
???? For mA-level precision current sensing in BMS or PD fast charging, choose an alloy current-sense resistor (e.g., EVER OHMS MA2512 series, 0.012R–0.05R / 2W, ±50PPM, MnCu/FeCrAl). The 3.9R 2512 resistor is oriented toward current limiting, voltage dividing, and load use.
- CRH2512J3R90E04S: 2512 / 3.9R / 5% / 2W / ±100PPM — cost-optimized for less precision-critical designs
- CRH2512J39R0E04Z: 2512 / 39Ω / 5% / 2W / ±100PPM, 200V working voltage — for higher-resistance voltage divider needs
