Ceramic Potentiometer Types & Applications Overview

Ceramic potentiometers are precision components widely used in electronic circuits to regulate voltage or control electrical devices. Unlike carbon or wire-wound potentiometers, ceramic potentiometers are known for their excellent stability, durability, and resistance to environmental factors such as humidity and temperature changes. These features make them ideal for applications that demand long-term reliability and high performance. What is a Ceramic Potentiometer? A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. In ceramic potentiometers, the resistive element is made from a ceramic material—typically a cermet (ceramic-metal composite)—which combines the mechanical stability of ceramics with the conductivity of metals. This hybrid structure enhances the lifespan and reliability of the ceramic potentiometer Ceramic potentiometers come in various forms, including through-hole, surface mount, and multi-tur...
