The IRC military chip resistor series provides precision and stable
performance in six industry standard chip sizes. IRC now utilizes two
film technologies to expand our options in size, resistance range and tolerance. IRC’s proprietary thick film
technology provides extended range and lower cost while our exclusive thin film (TaNFilm® tantalum nitride)
technology provides precision and superior performance in the harshest moisture environment.
