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
