不燃性金屬膜電阻器

Flame-proof Typ Metal Film Resistor - FMF Series

INTRODUCTION

The FMF series flame-proof Carbon Film Resistors are manufactured by Coating a homogeneous film of pure carbon on high grade ceramic rods, resistance less than 10 have an electro less deposited nickel film, and are coated with layers  of gray color flame-proof lacquer. These resistors meet overload tests in accordance with UL specification  without producing a fire hazard.
