CRH2512F390KE04Z 2512 390K 2W EVER OHMS Resistor – Complete Technical Analysis
1. Product Overview
The CRH2512F390KE04Z is a representative high-power thick film chip resistor from Taiwan-based EVER OHMS, belonging to the CRH series. It adopts a 2512 package (imperial, corresponding to metric 6432, i.e. 6.35mm × 3.2mm) with a resistance of 390kΩ, ±1% tolerance, and a rated power of 2W. The CRH series doubles the power rating compared to standard 2512 resistors (typically 1W) through optimized thick film processing and thermal design.
Established in 1988, EVER OHMS possesses comprehensive R&D and manufacturing capabilities in chip resistors and resistor networks. Its products are certified to ISO9001, IATF16949, and AEC-Q200 automotive standards. The CRH2512F390KE04Z serves as a key model in the brand‘s high-power product line, widely used in consumer electronics, communications equipment, industrial power supplies, and automotive electronics.

3. Technical Features and Application Advantages
High Power Density. Achieves 2W rated power in a standard 2512 package—double the typical 1W rating of conventional 2512 chip resistors. This enables engineers to significantly increase circuit power handling capability without expanding PCB footprint.
Wide Temperature Range Operation. The -55℃ to +155℃ operating temperature range covers everything from cold environments to high-temperature conditions inside power supplies. The ±100ppm/℃ TCR ensures resistance stability across the full temperature spectrum, with drift in the parts-per-ten-thousand range per degree Celsius.
200V Operating Voltage. Provides ample voltage margin for high-voltage side circuit designs, including power supply snubber circuits and surge protection applications.
Automotive-Grade Quality. The EVER OHMS CRH series complies with AEC-Q200 automotive electronic component reliability standards, meeting the stringent requirements of automotive electronics, industrial control, and other reliability-critical applications.
4. Typical Applications
Leveraging its “small footprint, high power” characteristics, the CRH2512F390KE04Z finds broad applicability in the following domains:
-
Power Equipment: Snubber circuits, buffer networks, discharge resistors in switching power supplies
-
Communications Equipment: Base station power supplies, current limiting and voltage dividing in communication modules
-
Industrial Control: Braking resistors and sampling circuits in inverters and servo drives
-
Automotive Electronics: BMS battery management system balancing sampling, ECU control boards
-
Consumer Appliances: Mainboard circuits in air conditioners, refrigerators, and other home appliances
-
Measuring Instruments: Precision voltage divider networks in electricity meters and navigation equipment
Important note: The 2W rated power is measured under standard pad dimensions and good thermal dissipation conditions. In applications with limited PCB heat dissipation, designers should allow a margin and derate to approximately 1.5W for long-term reliability.
