Carbon film resistors are those type of fixed resistors in which a carbon film is used for its resistive operation. Similarly for a low resistance value, a thick layer is chosen. Thus in a single line we can define a carbon film resistor as: Carbon film resistor is a fixed resistor that uses a carbon film that is deposited on a ceramic former, to restrict the flow of current. Typical tolerance values for carbon film resistors are 2, 5, 10 and 20%.

The helical cut in the film increases the length of the current path. The noise level increases when current flows. Carbon composition resistors (CCR) are fixed form resistors.

One of these resistor type is the carbon film resistor, which we would be discussed in this article. For a high resistance value, a thin layer is chosen.

Although carbon composition resistors are widely applied in circuits, the majority of resistors are nowadays  made by deposition of a metal or carbon film over a ceramic carrier. So the thermal mass of the carbon composition resistor is much higher, resulting in a higher energy capability. possibility of free electrons collision with the atoms is high. Hence, the carbon film blocks some amount of electric current. The product detailed below complies with the specifications published by RS Components. Carbon composition resistors are applied in the equipment or the leads and have to withstand all pulse energy. The resistance of the carbon film resistor is The two end caps shown in figure are actually metallic and the two connecting leads made of copper are joined at the two ends of these metallic caps. Press Esc to cancel. Hence, the of carbon film resistor, Copyright electric current have to travel only a small distance through To vary the dissipation, resistors are made with different diameters to provide a large enough surface to dissipate heat.

When current flows through the resistor, the entire carbon composition body conducts the energy. They are made out of fine carbon particles mixed with a binder (for example clay). increase in temperature is called negative temperature In the past some resistors were made without coating.
