The UAL25-500RF is a part of Riedon's high voltage wirewound resistor family. It is a long-term, stable, high-performance, and oversized, non-inductive power resistor design for high voltage applications. It features a stainless steel flanged housing, and a self-extinguishing flame retardant epoxy coating. The UAL25-500RF has a resistance range from 0.01 ohms up to 10 kilo ohms and has a peak power rating of 500 watts. It comes with an additional terminal, which improves the current capacity and long-term stability. The UAL25-500RF can handle temperatures ranging from -55 to +105 degrees Celsius, and features a radial leads insulated with glass fiber, which is molded and coated with a thermally stable insulating material. Lastly, the UAL25-500RF is UL recognized, and manufactured in compliance with RoHS and WEEE regulations.
