Trimmer Potentiometers, such as the TC86W-1-105, are specially designed variable resistors which make fine adjustments in a circuit. Capacitors, integrated circuits (ICs), and speakers are some of the components they control. Common applications of trimmer potentiometers involve voltage division, position sensing, and frequency compensation.

The working principle behind trimmer potentiometers is simple. They are composed of three terminals: a living part, a sliding part, and a rigid part. The living part is usually a resistance element which is resistive to current passing through it. A variable resistor, such as the TC86W-1-105, consists of a sliding part and a living part. The slide part is a mechanical device which is connected to a rotating dial. The dial controls the electricity flow in the living part, and thus modulates the resistance. By turning the dial, the user can adjust the resistive value from the trimmer potentiometer, and as a result, the voltage will be varied.

Trimmer potentiometers such as the TC86W-1-105 serve a variety of applications. One of the most common applications is voltage division. When Voltage dividers are used to divide a voltage source, the TC86W-1-105 can be used as a divider, by adjusting the dial in order to achieve the desired voltage level. Another common application of the trimmer potentiometer is position sensing. By connecting the trimmer potentiometer to a linear actuator, it can be used to measure the linear position. Finally, trimmer potentiometers can also be used for frequency compensation. In such an application, by adjusting the dial, the frequency can be tuned to the desired level.

Overall, the use of trimmer potentiometers, such as the TC86W-1-105, is widespread in electronic circuit design. These potentiometers are used to finely adjust various components, provide voltage division, sense linear position, and offer frequency compensation. By having a better understanding of the working principle and applications of trimmer potentiometers, engineers can have the tools to tackle any design challenge.
