Critical Parameter Analysis:
Power density breakthrough is the core technical feature. Standard 2512 package thick film resistors typically offer only 1W rated power, while the CRH series achieves 2W through optimized thick film paste formulation, ceramic substrate thermal paths, and multi-layer termination electrode design.
Temperature characteristics: TCR strictly controlled at ±100ppm/℃, operating range -55℃ to +155℃. Compared to standard CR series (TCR typically ±200ppm/℃ to ±400ppm/℃), CRH maintains stable resistance accuracy in industrial power supplies and automotive wide-temperature applications.
Short-term overload: 3W for 10 seconds.
Environmental compliance: RoHS compliant (2011/65/EU), REACH SVHC-free, with IATF 16949 and AEC-Q200 automotive certification.
