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
