Wirewound Resistors, Industrial Power, Tubular, Flat, Oval,

Adjustable, OVSA

FEATURES

• Terminal bands are spotwelded onto the

insulated core and resistance-alloy wire is

precisely wound onto the oval core

• The wire is spotwelded to the terminal bands

and then “locked” onto the core with a silicone

or cement coating

• Available as fixed and adjustable resistors (for fixed Oval

Resistor see www.vishay.com/doc?31835)

•Wirewound

• Material categorization: For definitions of compliance

please see www.vishay.com/doc?99912

Notes

• Ratings are based on a temperature rise of 300 °C above an ambient of 40 °C.

(1) Standard fixed resistance tolerance ± 5 %. Resistance values less than 1

 and adjustable have ± 10 % tolerance. Closer tolerances

available upon request.

Notes

• Ratings are based on mounting on a steel panel 10" x 10" x 0.040". Derate by 29 % when mounting on non-heat conductive surface.
