YAGEO CORPORATION LEADED RESISTORS
Metal Oxide Film Resistors FLAME-PROOF TYPE
Normal & Miniature Style [ RSF Series ]
INTRODUCTION
These Metal Oxide 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 & the miniature style of RSF
series are coated with layers of gray and pink
colors flame-proof lacquer respectively.
