Automated winding, in-line color banding, and testing allow for an economically priced, industrial grade wirewound power resistor. The Ohmite 50 series resistors feature an all welded construction with a high purity alumina ceramic core and high quality RoHS grade tinned copper wire. These design elements produce better thermal characteristics. The 50 series accompanies Ohmite's wide range of axial leaded products and if offered in popular 3 and 5 watt sizes up to 20K ohms in resistance value.
