50 Series Datasheet

Economical Silicone Coated Wirewound  

Res 50 product image

 

Automated winding, in-line color banding, and testing allow for an economically priced, industrial grade wirewound power resistor. These resistors feature an all welded construction with a high purity alumina ceramic core and high quality RoHS grade tinned copper wire instead of copper weld which produces better thermal characteristics. The 50 series accompanies Ohmite's wide range of axial leaded products.

 

Features

  • Rugged construction
  • Optimized for Medium to High volume production
  • Custom resistance values can also be produced on request
