UW Riedon™ Ceramic Wirewound Resistors

Bourns UW Riedon™ Ceramic Wirewound Resistors are designed with a flameproof design and provide an optional built-in standoff. These resistors are available in 2W to 15W power ratings, 0.01kΩ to 91kΩ resistances, and 1500VAC dielectric strength. The UW wirewound resistors feature ±20PPM/°C low Temperature Coefficient of Resistance (TCR). These resistors are RoHS-compliant and are available in non-winding options. The UW riedon resistors include all welded terminations and centerless ground ceramic core construction. These resistors are used in smart meters, solar inverters, telecom 5G remote radios, baseband units, and industrial power supplies.
