Product Number Decoding
CRH2512J10R0E04S is a standard model from EVER OHMS' CRH series of high-power thick film chip resistors. The product number breakdown is as follows:
- CRH: Chip Resistor High Power series, distinctly differentiated from the standard-power CR series.
- 2512: Package size code, corresponding to imperial 2512 (metric 6432), dimensions 6.35mm × 3.10mm.
- J: Tolerance code, indicating ±5%.
- 10R0: Resistance value, 10Ω.
- E04S: Internal coding for packaging and process version.
Product Characteristics
The CRH2512J10R0E04S is a 2512 10R 2W thick film chip resistor with the following key specifications:
| Parameter | Specification |
|---|---|
| Type | Thick Film Resistor |
| Package | 2512 (6432 metric) |
| Resistance | 10Ω |
| Tolerance | ±5% |
| Power Rating | 2W |
| TCR | ±100ppm/℃ |
| Max Operating Voltage | 200V |
| Operating Temperature | -55℃ ~ +155℃ |
The most notable technical feature is the breakthrough in power density. For the 2512 package, standard CR series typically offer 1W, while the CRH2512 delivers 2W—a 100% increase. This improvement is achieved through optimized thick film processes and thermal design, enabling the 2512 10R 2W specification to balance power density with layout flexibility in a compact footprint.
Additional features include small size, light weight, high reliability, and excellent quality. The product is RoHS compliant and covers an operating temperature range of -55℃ to +155℃, meeting the basic requirements for industrial-grade applications.
Applications
The CRH2512J10R0E04S 2512 10R 2W high-power chip resistor finds wide application across multiple sectors:
Consumer and Home Appliances: Power management and control circuits in products such as air conditioners and refrigerators, where 10Ω resistors are commonly used for current sensing and current limiting.
Computing and Peripherals: Motherboards, power modules, and other scenarios where 2512 10R 2W resistors are used for pre-charging, discharging, or high-voltage sampling in power circuits.
Power Supplies: Current sensing and current limiting in switching power supplies and DC-DC converters.
Industrial and Communications Equipment: Applications demanding high stability and reliability in industrial control and communications equipment.
Product Advantages
High Power Density: The 2512 10R 2W specification delivers 2W in a standard 2512 package—double the power of standard 1W products—effectively reducing PCB footprint.
Excellent Temperature Stability: The ±100ppm/℃ TCR ensures stable resistance values across a wide temperature range, critical for precision current sensing in power circuits.
Wide Operating Temperature Range: The -55℃ to +155℃ range suits diverse environments from consumer electronics to industrial applications.
Competitive Cost-Performance: Compared to international brands (e.g., Vishay, Yageo) offering similar 2W 2512 products, EVER OHMS delivers comparable core performance with better pricing and shorter lead times.
Authenticity Guaranteed: Sourcing through authorized channels ensures 100% genuine products, eliminating the risk of counterfeit or refurbished components.
Market Positioning
The CRH2512J10R0E04S occupies the mid-to-high-end thick film power chip resistor market. In the 2512 package, 2W power resistor segment, key competitors include Yageo's RC2512JK series. EVER OHMS differentiates itself through:
- Performance on par with international brands: Matching core metrics such as TCR and power density.
- Better pricing and availability: Particularly advantageous for mid-volume procurement.
- Superior quality over low-end domestic alternatives: Lower temperature drift and greater power headroom.
