Trimmer Potentiometers

A trimmer potentiometer, also known as a trimpot, is a hybrid form of potentiometer. It is an adjustable resistor through which an amount of resistance can be adjusted into an electrical circuit. It is a mechanically adjusted variable resistor with three terminals which acts as an adjustable voltage divider.

Y0059500R000J14L application field and working principle

The Y0059500R000J14L is a trimmer type of potentiometer that is most often used for voltage adjustment, current adjustment, gain control, linearizing an amplifier response, and other applications that require an adjustable potentiometer. It has a rated resistance between 100 ohms to 1 K ohms.

It functions as a voltage divider. A variable voltage is obtained across the wiper terminals by adjusting the resistor element. The winding adjuster present in the center of the potentiometer is adjusted to vary the effective area of the resistive element. The voltage is then adjusted by rotating the adjuster until the desired voltage is achieved.

The voltage generated is also dependent on the resistance of the potentiometer. Higher values of resistance result in higher values of voltage and vice versa. Trimmer potentiometers are mainly used to adjust signal parameters or the circuit without the need for power.
