Farad. A
unit of electrical capacity.
Fatigue Resistance. Resistance to metal
crystallization which leads to conductors or wires breaking
from flexing.
FEP. Fluorinated Ethylene Propylene is
a "Teflon" fluorocarbon resin and is a registered T.M.
of the DuPont Company. This is a melt extrudable fluorocarbon
resin.
Fiber. A thread or threadlike structure.
Also, a single discrete element used to transmit optical
(light wave) information.
Field. Area through which pass electric
and/or magnetic lines of force.
Filler. 1)A material used in multiconductor
cables to occupy large interstices formed by the assembled
conductors. 2) An inert substance added to a compound
to improve properties or decrease cost.
Film. A thin plastic sheet.
Flame Resistance. The ability of a material
prevent the spread of combustion by a low rate of travel
so the flame will not be conveyed.
Flammability. The measure of the materials
ability to support combustion.
Flammability Test. A test to determine
the ability of a cable to resist ignition when placed
near a source of heat of flame and to self-extinguish
when removed from this source. One more way the Multi/Cable
Q.C. department has to assure only the highest quality
products get shipped.
Flex Life. The measurement of the ability
of a conductor or cable to withstand repeated bending.
Flexible. That quality of a cable or
cable component which allows for bending under the influence
of outside force, as opposed to limpness which is bending
due to the cable’s own weight.
Flexibility. The ease with which a cable
may be bent.
Floating. Referring to a circuit which
has no connection to ground.
FR-1. A flammability rating established
by Underwriters Laboratories for wires and cables that
pass a specially designed vertical flame test. This designation
has been replaced by VW-1.
Frequency. Number of times an alternating
current reverses itself in one second. Expressed in Hertz
(Hz), which is one cycle per second.
Fuse Wire. Wire made from an alloy that
melts at a relatively low temperature.
Fused Spiral Tape. A PTFE Insulated hookup
wire. The spiral wrapped conductor is passed through a
sintering oven where overlaps are fused together.
