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
RMS
per inch of
winding length
• Hi-potential test at 1500 V
RMS
is available with higher
voltage tests available
• Wirewound
• Material categorization: For definitions of compliance
please see www.vishay.com/doc?99912
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.
(1) Standard fixed resistance tolerance ± 5 %. Resistance values less than 1
 and adjustable have ± 10 % tolerance. Closer tolerances
available upon request.
