CCR 1
Construction
Solvent Resistance
CCR series resistors are produced from a carbon ceramic
composite material, the composition of which is varied to
produce the required resistance value. The ceramic rods are
fitted with end caps to which are welded the termination
wires. Finally, a specially formulated high voltage epoxy
coating is applied and the resistors are marked.
The body protection and marking are resistant to all normal
industrial cleaning solvents suitable for printed circuits.
Marking
CCR series resistors are colour coded. Resistors with 20%
tolerance have three bands indicating value, and resistors with
5% and 10% tolerance have four bands indicating value and
tolerance in accordance with IEC62.

Pulse Performance
The graphs below show the value changes resulting from applying multiple pulses of increasing peak voltage. The pulse shape
was 1.2/50µS as defined in IEC 6100-4-5 / ANSI C62.41. The highest voltage plotted on each graph represents the maximum
peak voltage for that resistance value.
