Wirewound Resistors, Industrial Power, Tubular, Flat,

Oval, Fixed, OVSF

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 adjustable

Oval Resistor see www.vishay.com/doc?31836)

• Wirewound

• Material categorization: For definitions of compliance

Notes

•

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

Standard fixed resistance tolerance 5 ꢀ. Resistance values less than 1  and adjustable have 10 ꢀ tolerance. Closer tolerances

available upon request.
