1. INTRODUCTION
The FMF series flame-proof type Metal Film
Resistors are manufactured by vacuum
deposit metal film on high thermal conductivity
ceramic rods, and are coated with layers of
gray color flame-proof lacquer.
These FMF flame-proof metal film resistor is
designed to replace the metal oxide resistors
and low power wire wound resistors, where
when flame-proof and small size is needed.
