The carbon film resistor is one of the film resistors. Additional Information. The carbon composition contains materials with different heat expansion properties. Carbon film resistor construction. As it is less frequently failed than other units such as capacitor, the reliability and robustness of it are less concerned both in the academics and in the industries. Carbon Film Resistors are available at Mouser Electronics from industry leading manufacturers. The most commonly used film resistors can be divided into types according to the materials used: carbon-film, metal-alloy and metal-oxide. Carbon Film Resistors are available at Mouser Electronics from industry leading manufacturers. This carbon film restricts the flow and hence is the imperative part of this resistor. 470 Ohm 1 Watt 5% Carbon Film Resistor. 470 Ohm 1 Watt 5% Carbon Film Resistor. In the earlier 20th century, the carbon composition resistor is available with uninsulated bodies. A wirewound resistor can have a smaller physical size for a given power rating than carbon composition or film resistors, compare this 5W resistor with the 1W resistor at (labelled 3 in Fig.2.0.2). Carbon film resistor The carbon film resistor is formed by "cracking" a hydrocarbon onto a ceramic former. Hydrocarbons such as methane and benzene are shattered at a high temperature of 1000 °C. A carbon film resistor is a type of film resistor, which is also called thermal decomposition carbon film resistor. The carbon film resistor is made by placing the carbon film or carbon layer on a ceramic substrate. Prototyping packs and bulk packs available for manufacturers. Note A variable resistor is a resistor of which the electric resistance value can be adjusted. Carbon film resistors are a significant improvement on carbon composition resistors. Wirewound resistors however, do not not have the close tolerance of composition or film types. Carbon composition resistors were used for over 100 years but are rarely used today. For example, if a 10 kΩ resistor with a 1% tolerance undergoes an ESD event that changes its resistance to 11 kΩ (10% deviation), the device would still be able to function as a resistor; however, its altered parameters would no longer be suitable for its original function. Carbon Film Resistor. Resistors are components that oppose the flow of electrical current. It is due to this reason, the resistor is named "carbon film . Metal film resistor: Unlike carbon film resistors, this type of resistors incorporates a stable ceramic core coated with metal, such as Ni-Cr.
