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.
