Carbon film resistor

The carbon film resistor is one of film Resistors. Carbon film resistors are prepared by coating a suspension of carbon ink, graphite and fillers on an insulating substrate with an organic binder and polymerizing them by heating. Gaseous hydrocarbons decompose at high temperature and vacuum, and carbon is deposited on porcelain rods or tubes to form a crystalline carbon film. Therefore, carbon film resistance is also called "thermal decomposition carbon film resistance".

Metal oxide film resistor

Metal oxide film resistor is a special metal or alloy resistance material, with vacuum coating or cathode sputtering process, the specific metal or alloy (such as nickel chromium alloy, tin oxide or tantalum nitride) deposited on the insulating substrate (such as molded phenolic plastic) on the surface of the thin film resistor.

Wire-wound resistor

A wire-wound resistor is a type of fixed resistor. The wire wound resistor is formed by winding the resistance wire on the insulating skeleton. Resistance wire is generally made of nickel chromium, manganese copper and other alloys with a certain resistivity. The insulating skeleton is made of ceramic, plastic, metal coated with an insulating layer and other materials, such as tubular, flat and other shapes. Resistance wire can be wound on the skeleton according to the needs of a layer, can also be wound multi-layer, or the use of non-sense winding method. Wound resistors are mainly used in precision instruments, telecommunications instruments, electronic equipment and other AC and DC circuits for voltage division, voltage reduction, shunt and load resistance.

Cement resistor

Cement resistor is a resistor potted with refractory clay, that is, the resistor wire is wound on a non-alkaline heat-resistant porcelain piece, and the outside is protected and fixed with heat-resistant, moisture-resistant and corrosion-resistant materials. The wire-wound resistor body is placed in a square porcelain frame and filled and sealed with special non-combustible heat-resistant cement. Cement resistors have ordinary cement resistors and cement wire wound resistors.
