Wire Bondable High Range Chip Resistors IRC Advanced Film Division WBC-CR Series • New CHROMAXXTM film system • Discrete or tapped schematics • MIL inspection available • High resistor density IRC’s WBC-CR series now brings higher ohmic range thin film capabilities to hybrid applications. Using IRC’s new CHROMAXXTM film system on silicon substrates provides thin film performance on an extremely small footprint. Custom resistance values, sizes and schematics are available on request from the factory.
