I. Product Overview
CRH2512F11R0E04Z is a representative model from Ever Ohms Technology’s CRH series of high-power thick film chip resistors. Founded in 1988 and headquartered in Kaohsiung, Taiwan, Ever Ohms Technology is a professional manufacturer specializing in the R&D and production of chip resistors, resistor arrays, and precision electronic components. Its products are certified to ISO 9001, IATF 16949, and AEC-Q200 automotive standards.
This model adopts the 2512 imperial package (metric 6432, dimensions 6.35mm × 3.20mm), with a nominal resistance of 11Ω (11R), tolerance of ±1% (Grade F), rated power of 2W, and a temperature coefficient of ±100ppm/℃. As a 2512 11R 2W resistor, CRH2512F11R0E04Z achieves significant power density improvement within a standard package size and is widely used in power management, industrial control, automotive electronics, and other fields.
II. Model Number Decoding
The model number CRH2512F11R0E04Z follows Ever Ohms’ standardized naming convention, with each character corresponding to a specific technical meaning:
| Field | Meaning | This Model |
|---|---|---|
| CRH | Series prefix: High-power thick film series | Differentiates from CR series conventional power design |
| 2512 | Package size: Imperial 2512 | 6.35mm × 3.20mm |
| F | Tolerance grade | ±1% |
| 11R0 | Resistance code (R denotes decimal point) | 11.0Ω |
| E04Z | Suffix: TCR group + packaging code | ±100ppm/℃ |
“CRH” identifies the high-power thick film series, the following four digits represent the package size, the letter F indicates ±1% tolerance, the resistance code combines numbers and letters, and the E04Z suffix corresponds to the temperature coefficient and packaging specification. Taking the 2512 package as an example, conventional thick film resistors typically offer 1W power, while the CRH series achieves 2W—a 100% increase in power handling capacity.
III. Core Technical Characteristics
3.1 High Power Density Design
CRH2512F11R0E04Z achieves 2W rated power within the standard 2512 package, doubling the power handling capacity compared to conventional thick film resistors of the same size. This breakthrough stems from Ever Ohms’ continuous optimization of thick film materials and multi-layer terminal electrode design—utilizing high-purity alumina substrates and ruthenium-based resistor pastes, combined with 850℃ high-temperature sintering processes to ensure long-term drift-free operation. For power supplies, industrial controls, and communication equipment with limited space and thermal management constraints, this 2512 11R 2W resistor delivers higher power within limited PCB area, effectively reducing the number of parallel resistors and PCB footprint.
3.2 Wide-Temperature Stability
This model maintains a temperature coefficient within ±100ppm/℃ and operates across a temperature range of -55℃ to +155℃. The ±100ppm/℃ low TCR ensures consistent resistance values across a wide temperature range. Combined with its broad operating temperature capability, CRH2512F11R0E04Z is suitable for various demanding applications from low-temperature environments to high-temperature industrial scenarios. This characteristic is particularly critical in applications such as new energy vehicle BMS and industrial servo drives, where temperature stability is paramount.
