The RSF Series Metal Oxide Film Flame-Proof

Resistors offer excellent performance in

applications where stability and uniformity of

characteristics are desired. They provide lower

cost alternatives to Carbon Composition

Resistors and General Purpose Metal Films.

Metal Oxides also can replace many low power

General Purpose wirewound applications, saving

both money and time, with shorter delivery

cycles. The normal style & ‘RSF-WV’ style of

RSF series are coated with layers of gray flame-

proof lacquer, and the miniature style except

‘RSF-WV’ style are coated with layers of pink

colors flame-proof lacquer.
