What is a trimming potentiometer?
Trimmer Resistors A trimmer potentiometer, also known as a trim pot, is a type of variable resistor or adjustable potentiometer that can adjust, tune, and calibrate circuits. These trimmer resistors are often used to initially calibrate equipment after manufacturing.
How do trimmer potentiometers work?
Rotary and trimpot potentiometers are wire wound, and are single or multi-turn, depending on the number of times the knob may be turned. Potentiometers work by having a resistive element inside. Both end terminals are attached to it, and do not move. The wiper travels along the strip when the knob is turned.
What are trimmer potentiometer used for?
A trimpot or trimmer potentiometer is a small potentiometer which is used for adjustment, tuning and calibration in circuits. When they are used as a variable resistance (wired as a rheostat) they are called preset resistors.
What are the trim pots?
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.
Where can I find the technical details of the Trimpot?
Note: Complete Technical Details can be found at the trimpot datasheet given at the end of this page. Potentiometers also known as POT, are nothing but variable resistors. They can provide a variable resistance by simply varying the knob on top of its head.
What is A trimpot or Trimmer Potentiometer?
A trimpot or trimmer potentiometer is a small potentiometer which is used for adjustment, tuning and calibration in circuits. When they are used as a variable resistance (wired as a rheostat) they are called preset resistors. Trimpots or presets are normally mounted on printed circuit boards and adjusted by using a screwdriver.
