Browse Potentiometers, Variable Resistors electronic components with sourcing support for active, obsolete, hard-to-find and long lead time part numbers.
184 products found.
Potentiometers and variable resistors use a movable wiper on a resistive element to provide an adjustable voltage divider or resistance. The category includes panel controls, trimming potentiometers, rheostats and precision single- or multi-turn devices made with cermet, conductive plastic, carbon or wirewound elements. They support circuit calibration, level and speed adjustment, user controls and position sensing in industrial, audio, instrumentation and electronic equipment.
Select a device by total resistance, tolerance, resistance law or taper, rated power and maximum working voltage. Confirm single-turn or multi-turn adjustment, resolution, temperature coefficient, contact resistance variation and expected mechanical or rotational life. Match the number of gangs, shaft and bushing dimensions, actuator style, mounting direction, terminal layout and sealing level. For rheostat use, verify wiper current and power derating; for sensing applications, check linearity and repeatability. Complete suffixes often define mechanical options, so similar resistance values do not ensure interchangeability.
