Product Advantages
1. Double the Power Density. While conventional 2512 thick film resistors cap at 1W, the CRH series delivers 2W in the same footprint — a power density of 70 W/cm², over 5× that of thin film alternatives. This allows designers to double dissipation capacity without enlarging board area.
2. Superior Thermal Design. The 96% alumina ceramic substrate improves thermal conductivity by ~40% versus standard substrates. The ruthenium oxide thick film layer reaches 100μm in thickness, enhancing both power handling and pulse-withstand capability.
3. Wide-Temp Stability & Surge Immunity. Stable operation from -55℃ to +155℃. Withstands 2× rated voltage transient pulses and 100A/5ms surge currents — providing ample safety margin in hot-swap, motor-start, and lightning-surge scenarios.
4. Controlled Precision. ±1% resistance tolerance (F version) with ±100 ppm/℃ TCR ensures minimal drift under temperature variation, suitable for precision current sensing and voltage division.
Typical Applications
- Industrial Control: Current shunt and over-current protection in PLCs, VFDs, servo drives — the 2W rating reduces PWM linearity error
- Power Supplies: Load detection, feedback networks, surge suppression, and snubber resistors in SMPS, DC-DC converters, and 45W PD chargers
- Automotive & BMS: Voltage sampling and balancing circuits in EV battery management systems; 200V working voltage covers 400V powertrain divider networks
- Telecom: Over-voltage protection networks in 5G base station PA modules, dissipating lightning surge energy
- Consumer & Appliances: Power modules in HVAC, refrigeration, and computer motherboards
