Trimmer potentiometers are electrical components used to control resistance (resistance values), commonly used to adjust parameters or settings in electronic circuits, such as sound or volume level, etc. ST5ETP103 is a type of trimmer potentiometer with a wide range of application. This article will discuss on its application field and working principle.

Application Field

ST5ETP103 is a multi-turn, surface mount trimmer potentiometer with two units of single turn adjustment wires. This trimmer can be used to calibrate, adjust or fine-tune a wide range of electrical or electronic devices. Its application fields range from kitchen appliances, such as electric cookers and microwaves, to automobile radios and audio amplifiers.

Also, this trimmer is available in two versions, double-wiring version and single-wiring version. The double-wiring version is used for adjustment of two terminals, and the single-wiring version is used for adjustment of one terminal. Therefore, both of them can be used for general applications, such as adjust the operation voltage and current of battery chargers, and more. Furthermore, ST5ETP103 is typically used as the regulator for controlling the working voltage of integrated circuits in digital circuits. Therefore, ST5ETP103 is a widely used trimmer potentiometer.

Working Principle

ST5ETP103 is a type of potentiometer, which is a three-terminal resistor with an adjustable middle terminal. By adjusting the middle terminal, the resistance value of the trimmer can be varied to control current and voltage in a circuit. The two ends of the trimmer are the fixed terminals and the middle terminal is the adjustable one. This middle terminal is connected to a wiper which makes contact with the resistance material on the track and changes the resistance value of the trimmer accordingly.

The resistance value of ST5ETP103 can be adjusted by rotating the pin on the center of the trimmer. By rotating the pin in clockwise or anticlockwise direction, resistance value of the trimmer can be gradually increased or decreased. So, the user can use this principle to adjust the resistance of the trimmer to set parameters or settings accurately.

Conclusion

ST5ETP103 is a widely used trimmer potentiometer with a wide range of application. This trimmer can be utilized to regulate and calibrate the operation voltage of integrated circuits or electronic devices. Its principle is to adjust the middle terminal of the trimmer to vary the resistance value and manipulate current and voltage in a circuit. Hence, due to the functionality of ST5ETP103, this trimmer is suitable for a variety of settings and applications.
