PDF File Data Spec Flame-proof Typ Metal Film Low Ohm Resistor - FML Series (不然性)

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.
