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:
for definitions of compliance please see
www.vishay.com/doc?99912
Note
*
This datasheet provides information about parts that are RoHS-compliant and / or parts that are non-RoHS-compliant. For example, parts
with lead (Pb) terminations are not RoHS-compliant. Please see the information / tables in this datasheet for details.
