INTrOdUCTION
The FMP Series Metal Film Power Flame Proof
Resistors are manufactured using vacuum sputtering
system to deposit multiple layers of mixed metals al-
loy and passivative materials onto a carefully treated
high grade ceramic substrate. After a helical groove
has been cut in the resistive layer, tinned connecting
leads of electrolytic copper are welded to the end-
caps. The resistors are coated with layers of pink
color lacquer.
