Trimmer potentiometers, such as 416PA203M, are often called variable resistors, and they are used to control the flow of electric current. They typically have three terminals — a resistive element, a slider, and a third terminal. By adjusting the position of the slider, the resistance between the two terminals changes, controlling the flow of electricity between them. The resistive element of the 416PA203M is rated at 203 ohms, and is housed in a miniature plastic package with screw terminals for easy installation.

Application Field

Trimmer potentiometers, such as 416PA203M, are used in a variety of applications. They are often used for basic circuit adjustments and calibration, as well as for volume control of audio equipment. They are also frequently used as part of a more complex circuit, such as a voltage divider, where they are used to adjust the voltage level. In addition, they can be used to light indicators on devices such as timers or medical equipment.

Working Principle

The 416PA203M works on a very simple principle. It consists of two terminals, on which a resistive element (in this case a 203 ohm resistor) is connected. When the slider is in its central position, the resistance between the two terminals is equal to the value of the resistive element. When the slider is moved away from the center, the resistance increases, and when the slider is moved closer to the center, the resistance decreases. In this way, the resistance between the two terminals can be adjusted.

Trimmer potentiometers can also be used to create an adjustable voltage divider, which is useful for testing circuits or for voltage sensitve devices. In this type of application, the 416PA203M is connected in series with a fixed resistor, and the voltage level at the slider terminal of the variable resistor can be adjusted. When the slider is positioned between the two terminals, the voltage at the slider terminal is equal to the voltage applied to the resistor divided by the resistance of the two resistors in series.

The 416PA203M is a small and easy to install potentiometer, and its simple and versatile design makes it an ideal choice for a wide range of applications.
