Product Description
Product Overview
The RXM series wire-wound wafer resistors are non-flammable, coated resistors designed for applications in chargers, energy-saving lamps, and power supply units. They are constructed with a wire wrapping on a ceramic matrix, insulated with a non-flammable coating, and feature solvent-proof markings. These resistors offer a wide operating temperature range and various tolerance options.
