Wire Bondable Chip Resistors IRC Advanced Film Division WBC Series • Discrete or tapped schematics • MIL inspection available • 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 applications. Custom resistance values, sizes and schematics are available on request from the factory.
