Trimmer Potentiometers are small adjustable resistors used to control the flow of current in electrical circuits and devices. They are often referred to as "multi turn pots" or "trim pots" because they are capable of multiple adjustments. There are many types of trimmer pots available, but the one most commonly used today is a 72PR20KLFTB.

The 72PR20KLFTB trimmer potentiometer is a 3-terminal type, with one outer lug on the body and two other terminals. The 72PR20KLFTB features a multi-turn design allowing settings to be adjusted with a small screwdriver or pliers. It has a nominal resistance of 0.2kOhm to 4.7kOhm and is standardised in JIS EIA-7-7 package.

The working principle of the 72PR20KLFTB trimmer potentiometer is relatively simple. The outer lug of the trimmer (the common terminal) is connected to one side of the power supply. The two other terminals, the adjusting screw and the wiper, are connected to the other side of the power supply. When the adjusting screw is turned, the wiper moves along the resistance track, changing its position around the track and adjusting the resistance. By doing so, the amount of current flowing in the circuit is changed.

The 72PR20KLFTB trimmer potentiometer is used in a wide variety of applications. Its 3-terminal configuration makes it ideal for controlling voltage levels in electronic circuits such as voltage regulators, audio amplifiers, and lighting dimmers. It is also used as a replacement for variable resistors in a variety of actuator motor applications. In addition, they are used for ohmmeter calibration, wind speed control, oven temperature control, and distance measurement for robotics systems.

The 72PR20KLFTB trimmer potentiometer is a versatile device that offers a simple, yet effective way to control and adjust electrical circuits. It is designed to provide reliable performance in a wide range of applications and is easy to install and use.
