Carbon Film Fixed Resistors
Type CFR Series
Key Features
■
Low cost, combined with high
reliability, make these compo-
nents suitable for use in most
types of circuits, including
audio, communications,
measurement and computer
applications.
Premium quality carbon film
resistors whose ceramic core
has a high alumina content
offering power to size ratios
not normally associated with
carbon film product.
Available in 5 power ratings
from 1 ohm to 10 Mohm.
The smallest case size
(CFR16) has a full 0.25 W
power rating.

■
The resistive element comprises a thin film of carbon, deposited onto a high thermal con-
ductivity ceramic core. Metal end caps are force fitted to the element prior to spiralling to
value. Tinned copper lead wires are welded to the end caps and the components are then
coated. One coat of phenolic resin is followed by three coats of epoxy resin. All resistors
are tested for value and tolerance.
