Action of resistance

Resistance body is the most important component of 3362 adjustable resistance. Next, we will understand the relevant information of resistance body in detail.

Resistance body is a resistance component that provides a certain resistance value in 3362 adjustable resistance. Its electrical performance determines the main electrical performance of 3362 adjustable resistance. Resistance body should have good resistance value stability, small resistance temperature coefficient and static noise. In order to improve reliability, it should also have moisture resistance, heat resistance, wear resistance, oxidation resistance, high load resistance and resistance to sudden changes in heat and cold and other properties.

The resistance body of contact 3362 adjustable resistance, on which the moving contact contacts and slides, therefore, the surface of the resistance body has a low resistivity, so that its contact resistance with the moving contact is small; At the same time, the surface resistivity should be evenly distributed to keep the change of contact resistance and track resistance within the effective electrical stroke small, so as to obtain more ideal resistance characteristics. The surface of the resistance body should have proper finish, hardness and wear resistance to ensure its mechanical durability.

The adjustable resistance to wire winding 3362 is to wrap the resistance wire around the skeleton and make it into a circular or spiral resistance body. The adjustable resistance to film or thick film 3362 is to form a resistance film on the common substrate, which is usually shaped like a horseshoe, a circular arc or a long strip. For synthetic solid core 3362 adjustable resistance, horseshoe-shaped or elongated resistance rails are molded on the base.

According to the material of the resistance body, adjustable resistors can be divided into two categories: wire-wound resistors and non-wire-wound resistors, and non-wire-wound resistors can be divided into film type and forming type. Wire-wound type 3362 adjustable resistance is the resistance of the body is winding on the insulator high resistance alloy wire, film type 3362 adjustable resistance is the resistance of the body is a resistive film layer is deposited on the insulator, and synthetic 3362 adjustable resistance is the resistance of the body by the conductive particles and the binder (organic or inorganic) of mechanical mixture, it besides can make solid core resistor, can also be made into film type 3362 adjustable resistance, such as synthetic membrane 3362 adjustable resistance.
