Type FC Series
This small size pluggable, high power
resistor is a popular product in the
Tyco CGS range. The resistors are
wirewound on to an inert core of glass
fibre. The leads and end cap
assemblies are firmly crimped onto the
core and winding. A particularly
resilient silicone cement coating
provides an insulating, humidity proof
and flameproof seal. They are available
in a choice of height profiles and the
FCX type is supplied with axial leads.
The FC Series is widely used in moni-
tors, power supplies, white goods and
brown goods where a low cost, high
power resistor is required.
