TT electronics IRC Advanced Film Division introduces a series of wire bondable chip resistors designed for the most demanding hybrid applications. Designated the WBC Series, the resistors feature IRC’s self-passivating tantalum nitride thin film technology on silicon substrates. The self-passivating tantalum nitride resistor film provides stability over time and temperature, giving the WBC resistors good power dissipation. The wire bondable chip resistors are available in 0202 and 0303 chip sizes. The 0303 center-tapped chips can be used in feedback circuits of amplifiers, where ratio matching, high power and close tracking between two resistors is critical. Devices outside these specifications can be produced to meet specific customer requirements.
