Cermet Variable Resistor: Cermet variable resistors, also known as cermet potentiometers or cermet trimmer resistors, are valued for their exceptional stability and durability. This potentiometer variation has a fixed, compact form factor designed to be mounted on printed circuit boards (PCBs) with the intended use of precision applications ...

Digital Potentiometers. A digital potentiometer is a type of variable resistor that uses digital signals instead of mechanical motion to change its resistance. Digital potentiometers change resistance in discrete steps depending on the digital signal sent to it. They’re great for environments where vibration, dust, or moisture would gum up the shaft of a mechanical potentiometer.

A variable resistor is an electrical component that can be adjusted in resistance, making it useful for managing current, voltage, and signals in electronic circuits. Variable resistors, as opposed to fixed resistors, can change resistance over time within a specific range. Common types include potentiometers, which regulate audio levels and voltage; rheostats, which control current; and ...

The most important characteristic of a variable resistor is given by the relation between the mechanical position of the moving terminal and the resistance ratio. It is marked on the resistor as its taper. ... Applications of Variable Resistors. Variable resistors are mostly used where voltage control and current limiting is needed. In ...

Its main limitations are its sensitive nature to wear and vibration and its high cost as compared to variable resistors. Variable resistors. Variable resistors are used to adjust the resistance of a circuit. Its main types are single-turn variable resistor and multi-turn variable resistor. Its resistance value is some ohms to several kiloohms.

A digital variable resistor is a type of variable resistor where the change of resistance is not performed by mechanical movement but by electronic signals. They can change resistance in discrete steps and are often controlled by digital protocols such as I 2 C or by simple up/down signals. Symbols for Variable Resistors
