What is the shape of a carbon film resistor?

Carbon film resistors are a fixed form type resistor. They are constructed out of a ceramic carrier with a thin pure carbon film around it, that functions as resistive material. read more

Carbon film resistor applications. Typical use for carbon film resistors is in high voltage and temperature applications. Operating temperatures are up to 15kV with a nominal temperature of 350°C. Examples are high voltage power supplies, radar, x-rays and laser. Manufacturing. Carbon film resistors are made with a deposition process. read more

A resistor made of a film of carbon deposited on a substrate. Cuts are made in the film to allow generation of different resistance values. A spiral is used to increase the length and decrease the width of the film, which increases the resistance. read more

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 The figure below shows how a set of commercial carbon film resistors looks like. read more
