What kind of resistor is CRH2512F8R45E04Z 2512 8.45R 2W
CRH2512F8R45E04Z is a high-power thick-film chip resistor manufactured by Ever Ohms, designed for medium-to-high power density applications. The model code follows industry standards: CRH denotes the high-power thick-film series, 2512 is the imperial package size (6.35mm × 3.18mm), F indicates ±1% tolerance, 8.45R represents 8.45Ω resistance, 2W is the rated power, and E04Z specifies RoHS-compliant lead-free process and tape packaging.
Constructed with high-purity alumina ceramic substrate and ruthenium-based thick-film ink, sintered at 850°C, this resistor delivers superior thermal stability and mechanical robustness. It maintains full 2W power dissipation at 70°C ambient temperature—double the standard 1W capability of conventional 2512 packages—reducing PCB footprint and BOM cost. With a TCR of ±100ppm/°C, operating range from -55°C to +155°C, max working voltage of 200V, and AEC-Q200 certification, it excels in harsh environments.
Typical applications include current sensing in switch-mode power supplies, feedback networks in DC-DC converters, pre-charge limiting in motor drives, and auxiliary circuits in onboard chargers (OBC) and BMS. The 8.45Ω value enables precise high-current monitoring while withstanding transient surges.
Market-wise, it targets the mid-to-high-end industrial and automotive-grade segment, offering a balanced solution of performance, reliability, and cost-effectiveness. Ever Ohms, a seasoned Chinese passive component manufacturer with decades of experience, ensures consistent quality and global compliance.
