Product Description
Product Overview
The RXM series wire-wound wafer resistors are designed for applications in chargers, energy-saving lamps, and power supplies. They feature non-combustible coating and are suitable for continuous use at ambient temperatures up to 70C, with derating curves provided for higher temperatures. These resistors offer a wide operating temperature range and are constructed with nickel-chrome or copper-nickel alloy wire.
