Vishay Dale
Wirewound/Metal Oxide Resistors, Commercial Power, Axial Lead
FEATURES
High performance for low cost
Meets or exceeds requirements of EIA
Standard RS-344
High power to size ratio
Ceramic cases are available with circuit board
stand-offs (designated with a -3 model ending)
Special inorganic potting compound and
ceramic case provide high thermal conductivity
in a fireproof package
Compliant to RoHS Directive 2002/95/EC
Note
(1) To specifically order a Wirewound sub-assembly for resistance values that overlap between the Wirewound and Metal Oxide technologies,
the model will be a CPxxxx...85 for standard body and CPxxxx...91 for body with stand-offs. To specifically order a Metal Oxide
sub-assembly for resistance values that overlap between the Wirewound and Metal Oxide technologies, the model will be a CPxxxx...100
for a standard body and CPxxxx...101 for body with stand-offs. If no dash type is specified, either technology may be supplied.
Note
Wirewound CP resistors can reliably function as a fuse and as a resistor. Such components involve compromise between fusing and resistive
functions; therefore, each design should be tailored to the application to ensure optimum performance. Contact factory by using the e-mail
address at the bottom of this page for design assistance.
