Trimmer Potentiometers

Introduction

Trimmer Potentiometers (T.P.) is a type of variable resistors that can be used to modify the oscillation frequency of an oscillation circuit or to regulate the output voltage of a DC circuit. They are mainly used for trimming linearity errors or adjustment of the impedance of an oscillation circuit or the output voltage of a DC power circuit. T.P. offers high precision, high stability, long lifespan, and are relatively cost-efficient.

3386W-1-254LF Application Field and Working Principle

3386W-1-254LF is a trimmer potentiometer especially designed for use in automotive applications, for example, speed regulation, door locks, power steering and temperature control. The equivalent model number of 3386W-1-254LF is 250LF 2K2.

The working principle of 3386W-1-254LF is based on the principle of variable resistance. The unit is composed of a body, a rotor and contact points, all of which are intertwined.
