Aluminum-Housed Power Wirewound Resistors – UAL Series
This wirewound design from Riedon™ products by Bourns is designed for direct heatsink mounting with compound to give maximum performance in heated conditions
The robust UAL series from Riedon™ products by Bourns 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 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.
