What is a Trimmer Potentiometer?

A trimmer potentiometer (also called a trimmer or trim pot) is an adjustable three-terminal resistor, often used as an adjustable voltage divider. It is composed of two sections, the fixed resistor and variable resistor. The fixed resistor’s value is predetermined and the variable resistor’s resistance can be adjusted by its shaft or knob.

ST42EC503 Application Field and Working Principle

The ST42EC503 trimmer potentiometer is a device that enables control of voltages and currents in circuit designs. It can be used in the industrial, automotive, communications and consumer electronics applications.The ST42EC503 features a low-profile package, a broad resistance range from 10 Ω to 1M Ω and simple control of the resistance with its rotary shaft. It can be used on the board with 1320° rotatable angle and carrying a wide selection of power packages. The rated power ranges from 1/10W to 1W, making it suitable for various applications.The working principle of the ST42EC503 is based on the law of resistors, Ohm’s law and the fact that the resistance can be regulated by varying the currents in each section. The two sections of the potentiometer are connected in series. When the rotary knob is adjusted, the current flow will be divided between the fixed resistor and the variable one. The relationship between the fixed and variable resistors defines the internal resistance of the device in accordance with Ohm’s Law. The division of the current will determine the tension of the output voltage at the internal contact (wiper) of the potentiometer.
