Stackpole Announces the Release of the RNAN Thin Film Precision High Power Aluminium Nitride Substrate Chip Resistors

Thin film resistors are valued for their exceptional precision, stability, and performance, but they are traditionally limited to lower power ratings. This constraint has made it difficult to apply thin film technology in higher-power designs that still demand tight tolerances and long-term accuracy. By utilising an aluminium nitride substrate with significantly higher thermal conductivity, substantially greater power handling can be achieved without sacrificing the precision for which thin film nichrome resistors are known.

Stackpole says its newly released RNAN series leverages this advanced substrate technology to deliver high-power, high-reliability thin film chip resistors. The RNAN series offers industry-leading power density with ratings up to:

*0.5 W in 0603

*1 W in 0805

*2 W in 1206

*6 W in 2512

The company says these power levels are achieved while maintaining acceptable hot-spot and terminal temperatures — performance that is difficult to realise with conventional alumina-based high-power chip resistors.
