• High resistor density
IRC’s WBC series wire bondable chip resistors are
ideally suited for your most demanding hybrid
application. The WBC combines IRC’s TaNSil®
tantalum nitride thin film technology with silicon
substrate processing to produce an extremely small
footprint device with the proven stability, reliability and
moisture resistance of IRC’s TaNSil® resistor film.
