Wirewound Resistors, Commercial Power, Axial Lead
FEATURES
• High power to size ratio
• Ceramic cases are available with circuit board
stand-offs (designated with a -3 model ending)
• Superior surge capability
• Complete welded construction
• Available in non-inductive styles with Aryton-
Perry winding (CPWN in lieu of CPW, maximum
resistance is one-half CPW range)
• Special inorganic potting compound and
ceramic case provide high thermal conductivity
in a fireproof package
• Material categorization:
