Johanson Dielectric’s Resistor Wirewound Chasis Mount or RWC Series is designed for direct heatsink mounting with compound to give maximum performance in power applications for resistors. This robust series uses wirewound resistor technology in a large ceramic core molded into an extruded aluminum, chassis-mount housing. The wire wound design maximizes pulse handling capability, while the aluminum housing provides for superior heat conduction and resistance to very tough environmental conditions.
