Wire Bondable Ceramic Resistors WBA Series * High resistor density * Lower stray capacitance * Proven TaNFilm(R) on ceramic technology IRC's WBA series wire bondable ceramic resistors are ideally suited for your most demanding hybrid application. IRC's TaNFilm(R) tantalum nitride thin film technology has years of proven stability, reliability and moisture performance. IRC's WBA series of ceramic chip resistors offer a wide range of tolerances and temperature coefficients to fit a variety of hybrid circuit applications. Custom resistance values, sizes and schematics are also available on request to the factory. For high performance wire bondable ceramic resistors for hybrid circuit application, specify IRC WBA series resistors.
