Ceramic potentiometer

Cermet resistive elements incorporate a ceramic based ink which allows a higher level of heat absorption and dissipation than most other composite materials used in potentiometers. Cermet resistive elements also have a wider temperature operating range compared to other substrates. Hot Molded Carbon — Carbon based materials also exhibit a greater ability to absorb and dissipate heat than most other composites. Carbon resistive elements incorporate a carbon based ink film which, depending on the thickness of the ink film, can allow a higher level of heat absorption and dissipation than most other composite materials used in potentiometers. Thick film carbon potentiometers are comparable to Cermet in their ability to absorb and dissipate heat when they are incorporated onto a carbon molded base material. Conductive Plastic — Conductive plastic materials do not absorb and dissipate heat as well as Cermet or Carbon. Conductive Plastic resistive elements incorporate a conductive plastic based ink film deposited onto a plastic substrate. In all of the above examples, the ability of the potentiometer to dissipate heat is further enhanced by other mechanical parts used in the construction of the potentiometer. The primary dissipative path for heat generated by the resistive element is through the metal shaft and bushing. When the potentiometer is mounted in a metal panel the heat dissipation is further enhanced.

Ceramic potentiometer

A cermet potentiometer is a variable resistor made of ceramic-metal composite, offering low noise, stability, and precision in various electronic applications. A cermet potentiometer is a type of variable resistor that plays a crucial role in various electronic circuits and devices. This article provides an in-depth look at cermet potentiometers, their applications, advantages, and how they differ from other types of potentiometers. A cermet potentiometer is comprised of a resistive element made from a cermet material, which is a composite of ceramic and metallic materials. The cermet material is often a combination of metal particles, such as tungsten or platinum, and ceramic oxides, like alumina or beryllia. This composite material is then deposited onto a substrate, usually made of glass, ceramic, or a similar insulating material. The resistive element is connected to a pair of fixed terminals, while a third terminal, called the wiper, moves along the resistive track. As the wiper moves, it changes the resistance between the fixed terminals and the wiper, thereby allowing the user to control the output voltage or current in a circuit. The wiper is typically attached to a shaft, which can be rotated manually or adjusted by an automatic control mechanism.
