This structured naming system fully carries the complete electrical and physical parameter information, allowing engineers to make preliminary selection judgments based solely on the model number.
Product Characteristics
CRH2512F75K0E04Z is a 2512 75K 2W high-power thick film chip resistor with the following key parameters:
| Parameter | Specification |
|---|---|
| Package Size | 2512 (6.35mm × 3.2mm) |
| Nominal Resistance | 75kΩ |
| Tolerance | ±1% (Grade F) |
| Rated Power | 2W (@70℃) |
| Temperature Coefficient | ±100ppm/℃ |
| Operating Temperature Range | -55℃ ~ +155℃ |
| Maximum Operating Voltage | 200V |
The resistor is manufactured using thick film technology, with 96% alumina ceramic substrate as the carrier, through screen printing of ruthenium-based oxide paste followed by high-temperature sintering to form the resistive layer, with a glass glaze protective coating on the surface. The product complies with RoHS and REACH regulations, is compatible with reflow and wave soldering processes, and is suitable for automated SMT production lines.
The most prominent feature is power density. Standard 2512 package thick film resistors typically have a rated power of 1W, while the Ever Ohms CRH series elevates the power handling capability to 2W in the same physical footprint through ceramic substrate thermal optimization and thick film paste formula improvements.
Product Applications
The CRH2512F75K0E04Z 2512 75K 2W resistor, with its 75kΩ resistance and 2W power handling capacity, finds wide application across various scenarios:
Power Management: Used in switching power supplies and DC-DC converters as voltage divider resistors, feedback loop resistors, or inrush current limiting resistors.
Industrial Control: Employed in servo drives, motor control systems, and PLC systems as signal sampling resistors or current limiting resistors.
Automotive Electronics: Used in new energy vehicle battery management systems (BMS) for cell voltage balancing circuits and voltage divider detection loops.
Communications Equipment: Widely adopted in 5G base stations, routers, switches, and other communication devices.
Consumer Electronics: Extensively used in LED lighting drivers, audio equipment, tablets, smart home appliances, and more.
Product Advantages
Leading Power Density: Achieves 2W rated power in the standard 2512 package, doubling the power density compared to conventional products of the same size.
Excellent Environmental Adaptability: The thick film structure combined with ceramic substrate maintains stable resistance in humid, salt spray, and high-sulfur environments. The operating temperature range covers -55℃ to +155℃, meeting industrial-grade reliability requirements.
Outstanding Reliability: Passes high-temperature load tests, thermal cycling tests, and anti-sulfidation performance verification, suitable for applications demanding long-term stability.
Strong Cost Competitiveness: Thick film technology costs 40%~60% less than thin film technology, while the CRH series has passed AEC-Q200 automotive-grade certification, achieving a balance of "automotive-grade reliability + thick film-level cost."
Market Positioning
The Ever Ohms CRH series high-power resistors have a clear market positioning – combining the cost advantages of thick film technology with automotive-grade reliability to resolve the traditional contradiction between high power and high precision. The series is positioned in the mid-to-high-end power chip resistor market, primarily competing with TE Connectivity's CRGH series and Yageo's RC series.
Under the trend of domestic substitution, the CRH series occupies an important position in the medium-power thick film chip resistor market. It fills the market gap between ordinary thick film resistors and high-end thin film resistors, targeting mid-to-high-end industrial control, automotive electronics, communications equipment, and medical electronics fields that demand stringent reliability.
