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

* Pb containing terminations are not RoHS compliant, exemptions may apply
