Product Number Decoding
CRH2512J160RE04Z is the complete model number of Ever Ohms' high-power thick film chip resistor. "CRH" denotes the high-power resistor series; "2512" indicates the package size, corresponding to the standard 6.35mm × 3.2mm imperial 2512 package; "J" represents ±5% tolerance; "160R" is the nominal resistance of 160Ω; "E04Z" relates to packaging specifications and production batch information. This numbering system clearly reflects the core parameter combination of 2512 160R 2W, facilitating quick identification and selection for engineers.
Product Characteristics
The 2512 160R 2W Ever Ohms resistor belongs to the CRH series, with its most prominent technical feature being the "power upgrade" design. While maintaining the standard 2512 package, it increases power from the conventional 1W to 2W. Key parameters include: nominal resistance 160Ω (160R), ±5% tolerance, ±100PPM temperature coefficient (TCR), 200V rated voltage, 300V overload voltage, and an operating temperature range of -55℃ to +155℃.
The CRH series employs ruthenium oxide paste screen-printing technology, with the resistive layer formed on an alumina ceramic substrate through 850℃ high-temperature sintering, reaching a thickness of 100μm and a power density of up to 70W/cm². The product complies with RoHS and REACH environmental requirements and has passed ISO 9001, IATF 16949, and other quality system certifications.
Product Applications
The 2512 160R 2W resistor is primarily designed for applications requiring a balance between miniaturization and high power margin. Typical applications include:
- Industrial Power Supplies: Current limiting, voltage dividing, and discharge circuits in switching power supplies, frequency converters, and servo drives
- Automotive Electronics: Circuit protection in high-temperature environments such as battery management systems (BMS) and onboard charging modules
- Communication Equipment: Power distribution and surge protection in POE (Power over Ethernet) modules and base station power supplies
- New Energy: Energy conversion and circuit regulation in photovoltaic inverters and energy storage systems
For the 160Ω resistance value, this 2512 160R 2W resistor effectively prevents burnout caused by instantaneous surges in bus voltage sampling, discharge circuits, and pull-up/down circuits, thanks to its 2W power margin.
Product Advantages
- Power Density Breakthrough: Standard 2512 thick film resistors of the same size typically only achieve 1W, while the 2512 160R 2W doubles the rated power, significantly improving PCB space utilization
- Excellent Thermal Stability: The ±100PPM low TCR ensures resistance value changes remain controllable under high-temperature full-load conditions, preventing circuit logic failure due to heating
- Wide Temperature Range Reliability: The -55℃ to +155℃ operating temperature range is sufficient for various demanding industrial and automotive electronics environments
- Thick Film Process Cost Advantage: Compared to thin film or alloy resistors, the thick film process offers higher cost-effectiveness while maintaining performance
Market Positioning
The 2512 160R 2W resistor is positioned in the mid-power thick film chip resistor market, between ordinary consumer-grade resistors and high-end precision resistors. It is not intended for all electronic devices but precisely serves industrial power supplies, automotive electronics, and new energy sectors with clear requirements for power density. Achieving double the power within the same package size makes it the preferred solution for design scenarios where "space is limited but power cannot be compromised".
