40 Revision: 02-Nov-06
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
** 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

assistance.
