What is a Carbon Composition Resistor (CCR)?
CCR or carbon composition resistor encompasses a solid rod of conductive composition materials that
can be modified to create numerous resistance values.
Typically the composition of a carbon composition resistor exists of the blend of ceramic filler and
carbon, the relative amount of this mix influences the resistance.
The resistance value can be modified
by altering the ratio of filler to conductor.
There are interference-fit end caps that are connected to the
rods, leads are welded to the said caps and then a specially formulated epoxy covering will be utilized to
protect the resistor body.
Then last of all; the resistors will be color code marked.
If we will trace the historical past of CCR, we will discover that they have already been around over
hundred years ago.
At the beginning of the 20th century, the resistors were made without coating.
As
such, the lead wires were di
