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 & the miniature style
of RSF series are coated with layers of gray and
pink colors flame-proof lacquer respectively.
