High resistor density
IRC’s WBC series wire bondable chip resistors are ideally suited for
the 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 performance of IRC’s TaNSil
®
resistor film.
Available in a wide range of tolerances and temperature coefficients to fit a variety of hybrid circuit applica-
tions. Custom resistance values, sizes and schematics are available on request from the factory.
