Metal Case Resistor

FEATURES

• Terminal bands are spotwelded after
installation on the insulated core and
resistance-alloy wire is precisely wound onto
the core

• The wire is spotwelded to the terminal band
and then “locked” onto the core with a silicone coating

• Resistor is “potted” into the metal case with high
temperature cement

• Tapped stylus with single quick connect terminals, lugs, or
leads available

• Non-inductive winds and special temperature coefficients
can be provided

• Special terminals and mounting available for unusual
applications

• Maximum voltage limitation is 750 V
winding length

• Hi-potential test at 1500 V
voltage tests available

•Wirewound

• Material categorization: For definitions of compliance

Notes

• Ratings are based on a temperature rise of 275 °C above an ambient of 25 °C. Heat sink is a steel panel 10" x 10" x 0.040".

• Heat transfer to the heat sink is improved by the use of thermally conductive grease or epoxy.

Standard fixed resistance tolerance ± 5 %. Resistance values less than 1  and adjustable have ± 10 % tolerance. Closer tolerances
available upon request.
