They play an important role in the electronics industry and military aerospace fields with high precision requirements. They use high-temperature vacuum coating technology to tightly attach nickel-chromium or similar alloys to the surface of the porcelain rod to form a film, and then cut and adjust the resistance value to achieve the final required precision resistance value, then add appropriate joint cutting, and coat the surface with epoxy resin for sealing and protection.

It is made by high temperature vacuum coating technology to attach carbon tightly to the surface of porcelain rod to form carbon film, then cut with appropriate joints, and apply epoxy resin on the surface for sealing and protection. Its surface is often coated with green protective paint. The thickness of carbon film determines the size of resistance, and the resistor is usually controlled by controlling the thickness of film and cutting grooves. Carbon film resistor is also called "thermally decomposed carbon film resistor". It is a kind of thin film resistor in which carbon is deposited on the substrate by high temperature thermal decomposition of hydrocarbon in vacuum. It is low in price, stable in performance, and has a wide range of resistance and power.

This type of resistor is made by decomposing and depositing a hydrolyzed metal salt solution (such as tin tetrachloride and antimony trichloride) on the surface of hot glass or ceramic. The performance of resistors varies greatly depending on the manufacturing conditions. The main characteristics of this resistor are high temperature resistance, an operating temperature range of +140~235℃, overload use in a short time, a resistance temperature coefficient of ±3×10-4/℃, and good chemical stability. This resistor has a low resistivity, and the resistance of a low-power resistor does not exceed 100 kilo-ohms.

1/4W 1/2W 1W 2W 3W 4W 5W Wirewound resistors are a type of fixed resistor. Wirewound resistors are made of resistance wire wound on an insulating frame. Resistance wire is generally made of nickel-chromium, manganese-copper and other alloys with a certain resistivity. The insulating frame is made of ceramics, plastics, metals coated with insulating layers and other materials into various shapes such as tubular and flat. The resistance wire can be wound on the frame in one layer or multiple layers according to needs, or non-inductive winding can be used. Wirewound resistors are mainly used for voltage division, voltage reduction, current shunting and load in AC and DC circuits such as precision instruments, telecommunication instruments, and electronic equipment.
