Carbon Film Resistor

Carbon Film Resistor. The carbon film resistor is a fixed type resistor As such it means that it provides only a single resistance value Consequently the carbon film plays the role of the resistive material Namely it restricts current in a circuit Construction of The Carbon Film Resistor The carbon film resistor’s design is quite simple.

Carbon Film Resistor is prepared by depositing carbon film on the ceramic substrate which is an insulator The electric current is blocked to a certain extent by the carbon film On the contrary the insulating ceramic doesn’t let heat through it which in turn makes the carbon film resistor capable of withstanding massive temperature without being damaged.

The resistive material for the carbon composition resistor is a blend of graphite ceramic dust and resin The mixture is pressed into sticks under high pressure and temperature The connecting wires are centrally pressed in both ends of the resistor.

Carbon composition resistor It is a typical fixed resistor made from the mixture of granulated powdered carbon or graphite insulation filler or a resin binder The insulating powder binder is made in the shape of rods and there are two metal caps on the both ends of the rod.

What is a Carbon Film Resistor? (with picture)

Carbon film resistors are a type of fixed value resistor They are constructed out of a ceramic carrier with a thin pure carbon film around it This carbon film functions as the resistive materialAdvantages and DrawbacksApplicationsManufacturingCarbon film resistors are made with a deposition process At high temperature and under a high pressure a ceramic carrier is held in hydrocarbon gas The gas (methane or benzene) is cracked at a temperature of 1000 °C The crystalline carbon is pyrolytically deposited on the ceramic sub.
