Metal & Carbon Film Resistors

The carbon film resistor is one of the film resistors. It uses high-temperature vacuum coating technology to attach carbon to the surface of the ceramic rod to form a carbon film, and then cut it with a suitable joint, and the surface is coated with epoxy resin to protect it. The surface is often coated with a green protective lacquer. The thickness of the carbon film determines the magnitude of the resistance, and the thickness of the film and the groove are usually controlled to control the resistor. The carbon film resistor is also called "thermal decomposition carbon film resistor". A thin film resistor in which carbon is thermally decomposed at a high temperature in a vacuum deposited on a substrate. It characterized of low price, stable performance, wide resistance and power range.

The difference in appearance between the carbon film resistor and the metal film resistor: the metal film has five color rings (1%), and the carbon film has four color rings (5%). The metal film is blue, the carbon film is khaki or other colors. The carbon film resistor used to be the most used resistor for electronics, electrical appliances, and information products. It is characterized by low price, high reliability and stable quality. Because it is a lead-type resistor, it is easy to be installed and repaired, and it is also the cheapest in lead resistance.

 

With the advancement of technology, the demand of resistors continues to arise. There are many types of resistors. Metal & Carbon Film Resistors are just two of them. ExcessChip Technology Co.,ltd. recycle various types of resistors. Pls contact us if you have excess metal & carbon film resistors.
