All parts are Pb-free and comply with EU Directive 2011/65/EU (RoHS2)
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 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.
