CPW, CPWN
Vishay Dale
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
• Compliant to RoHS Directive 2002/95/EC
Notes
* Pb containing terminations are not RoHS compliant, exemptions may apply
** Please see document “Vishay Material Category Policy”: www.vishay.com/doc?99902
