1. INTRODUCTION
The FCF series flame-proof Carbon Film Resistors
are manufactured by Coating a homogeneous film
of pure carbon on high grade ceramic rods, resistance
less than 10Ω have an electroless deposited nickel
film, and are coated with layers of gray color flame-
proof lacquer. These resistors meet overload tests in
accordance with UL specification #1412 without
producing a fire hazard.
2.
FEATURES
Low cost, prompt delivery
High power-to-size ratio for significant space savings
Complete flameprrof construction-UL 1412
Excellent long-term stability
Wide resistance range : 1Ω ~ 10MΩ
Coating and marking resist Trichlorethelyne,
Freon, and other cleaning agents
