390 kΩ 2 W ±1% Tolerance High Power Thick Film Chip Resistor in 2512 Package for Industrial Applications

The EVER OHMS CRH2512F390KE04Z​ is a high-power thick film chip resistor in a 2512 footprint, rated at 390 kΩ, 1% tolerance, and 2 W​ — a member of the CRH series that pushes the 2512 package well beyond the conventional 1 W limit through ruthenium-based thick film technology on a 96% alumina ceramic substrate.

In power-dense designs, the 2512 390K 2W resistor hits the sweet spot between board space and power headroom. With a 200 V working voltage rating, the theoretical dissipation at full voltage is only ~0.1 W, leaving a generous safety margin under the 2 W ceiling. The ±100 ppm/℃ TCR ensures minimal resistance drift across industrial temperature swings, while the thick film construction absorbs transient surge pulses up to 2× the rated voltage.

Typical use cases include:

• Power supplies​ — auxiliary rail dividers, feedback networks
• Telecom​ — over-voltage protection in 5G RRU PA modules
• Automotive​ — BMS high-side voltage dividers for 400 V battery systems
• Consumer electronics​ — PD fast chargers, LED drivers
• Industrial control​ — servo drives, PLC signal conditioning

For production sourcing of this 2512 390K 2W resistor, Shenzhen Shunhai Technology Co., Ltd.​ maintains stable inventory of CRH2512F390KE04Z as an authorized EVER OHMS distributor, offering original parts with reliable lead times. The Huanian Mall (华年商城)​ online platform also stocks the full EVER OHMS high-power resistor lineup, supporting bulk quotation requests and real-time inventory visibility — well suited for prototype builds and low-volume procurement.

???? When placing an order, verify the full part number: CRH2512F390KE04Z (F = ±1%). If your design can tolerate ±5%, the equivalent CRH2512J390KE04Z shares the same package and power rating.
