Type CCR Series
The CCR series of resistors is
constructed utilising solid ceramic
composition, which is the traditional
medium for absorbing high energy
pulses, in cases of high inrush
current. These resistors have
evolved over many years to have
excellent pulse withstand capabili-
ties, whilst remaining very stable.
These improved characteristics
have been achieved by prudent
selection of materials of optimum
physical properties and by
advances in the manufacturing
process. The CCR series are
ideal for circuitry associated
performance in high voltage power
supplies, R-C snubber circuits, and
inrush limiters.
