UT Riedon™ High-Temperature Power Resistors

Bourns UT Riedon™ High-Temperature Power Resistors are silicone-coated resistors with superior pulse handling and temperature capabilities. These resistors are designed to Mil-R-26/Mil-R-39007 power ratings. The UT power resistors are available in 0.02kΩ to 320kΩ resistance range, 1W to 13W power ratings, and ±0.01% to ±10% (1% standard). These resistors are RoHS-compliant and are available with non-inductive windings. The UT power resistors are used in solar inverters, smart meters, current sensors, industrial power supplies, and baseband units.
