Description

Trim pots are also known as preset potentiometers used for adjustment, calibration and tuning purpose in circuits. They are easily mountable on PCB boards and adjusted by a screwdriver. The resistive track is made up of carbon composition or cermet. When replacing with normal potentiometers, remember their life span is not so long. There are different types of trimmer pots available in market such as through hole, smd, single and multi-turn variation.

 

How to Use a Trimmer?

To use a Trimpot potentiometer simply connect the CCW and CW terminal with positive supply and ground terminal respectively and get variable output voltage from the wiper terminal. To change the output voltage rotate the screw on the top of the Trim pot. This screw rotate the wiper placed inside the pot, which varies the resistance.

Applications

  • Voltage and Current Control Circuits
  • Used as volume control knobs in radios
  • Tuning or controlling circuits
  • Analog input control knobs
