RMAN Aluminum Nitride Chip Resistors Deliver High Power for Industrial and Automotive Electronics

What happened

Stackpole Electronics introduced the RMAN series chip resistors, combining thick film resistor technology with the heat-dissipating capability of an aluminum nitride (AlN) substrate for industrial and automotive electronics operating at high power or under sustained load. According to the source, aluminum nitride provides thermal conductivity several times higher than conventional alumina while maintaining electrical insulation. In terms of power specifications, the RMAN provides power ratings up to 2.4 W in the 1206 size and 3.4 W in the 2512 size, which the source states delivers substantially higher power capability than conventional alumina-based thick film designs in compact PCB footprints. Applications include gate and snubber resistors for IGBT, SiC, and GaN power modules, pre-charge, discharge, bleeder, and current-sensing functions in motor drives, power supplies, and inverters, as well as automotive battery management systems, onboard chargers, DC-DC converters, and inverter gate drives. Pricing varies by size, tolerance, and TCR; customers are directed to contact Stackpole or a franchised distribution partner for specific or volume pricing.
