IRC Advanced Film Division
IRC’s WBC-CR series now brings higher ohmic range thin film
capabilities to hybrid applications. Using IRC’s new CHROMAXX
TM
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.
