Carbon film resistor is a kind of film resistor. It adopts a high temperature vacuum coating technology to closely attached to the surface of the ceramic rod carbon film, and then add the appropriate joint cutting, and coated with epoxy resin to seal for protection. The surface is usually painted with green paint. The thickness of carbon film depends on resistance size, it is usually used the film thickness and the groove to control the resistor. The carbon resister is made by heating polymerization, which uses an organic adhesive to make a suspension liquid by the carbon ink, graphite and the filling material and then be coated on the insulating substrate. Gaseous hydrocarbons are decomposed in high temperature and vacuum, the carbon is deposited on a ceramic rod or a ceramic tube to form a layer of crystalline carbon film. changing carbon film thickness and carving groove to change the length of the carbon film, we can get different resistance. The carbon film resistance has low cost, poor electrical performance and stability, which is generally not suitable for general purpose resistors. But because it is easily made of high resistance film, it is mainly used for high resistance high voltage resistor. Its functions are same to the high voltage resistor. The error rate of carbon film resistors is generally divided into three grades: The error rate of level I is 5%, the error rate of level II is 10%, and the error rate of level III is 20%
The carbon resister is made by heating polymerization, which uses an organic adhesive to make a suspension liquid by the carbon ink, graphite and the filling material and then be coated on the insulating substrate. Gaseous carbon with high voltage resistor. the large diameter resistor has a great power. The carbon film resistor has an axial lead, a tie lead and non-lead wire. the values carbon film resistor range from 1Ω~10MΩ. Rated power has 0.125W, 0.25W, 0.5W, 1W, 2W, 5W, 10W, etc.. the common carbon film resistors has a larger body, in order to adapt to the needs of small volume resistance device, and now it has produced a small carbon film resistor RTX type, the power is only 0.125W and the most are colour coded resistors. Carbon film resistors is commonly used the symbol RT, R represents the resistor, and T represents that the material is carbon film. The main function is to impede the flow of current, and is applied to the current limit, shunt, buck, partial pressure, load and capacitor matching filter and resistance matching, etc.. Because it is the lead resistance, it is convenient to manual installation and maintenance, but also the price of lead resistance is the cheapest. And now, most use the low value of low-end products or early products, such as power?supply and adapters.
