Aluminum-Housed Power Wirewound Resistors

This wirewound design from Riedon is designed for direct heatsink mounting with compound to give maximum performance in heated conditions

Image of Riedon's Aluminum-Housed Power Wirewound ResistorsRiedon’s robust UAL series utilizes wirewound resistor technology in a large ceramic core molded into an extruded aluminum, chassis-mount housing. The wirewound design maximizes pulse handling capability, while the aluminum housing provides for superior heat conduction and resistance to very tough environmental conditions.

The UAL series is available in 7.5 W to 50 W sizes with low +/- 1% tolerances and resistances from 0.1 Ohms to 100 kOhms. Higher power ratings up to 300 W are available through Riedon.
