50 Series
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 prod-
ucts.
