Potentiometers, Trimmers & Rheostats

Potentiometers are three-terminal resistors that allow you to change the location of the output contact to allow for resistance values that can be easily adjusted to control circuit levels. Two-terminal variable resistors called rheostats are strict variable resistors, which function similarly to potentiometers: With a third terminal left unconnected, a three-terminal potentiometer can be used as a rheostat. Trimmers are a type of potentiometer that require only infrequent adjustments, used to calibrate a device. These products are frequently used in machinery and other heavy equipment, marine vehicles, audio equipment, televisions, and equipment calibration.

Symmetry offers potentiometers, trimmers, and rheostats from Murata, an industry leader.
