Trimmer potentiometers, such as the FT63ETH104, offer a fine-tuning adjustment to circuits and are commonly found in a variety of electronic applications. This article will discuss the application fields of the FT63ETH104 trimmer potentiometer, as well as an explanation of its working principle.

Applications of FT63ETH104 trimmer

The FT63ETH104 has a variety of uses a modular contacts fixed on a plastic rotor or spindle. It features a three terminal design and works as a digital analog controller.
Trimmer potentiometers can often be used to fine-tune circuits as a way to reduce background noise and improve the accuracy of the circuit. The FT63ETH104 is commonly used in precision and medical instrumentation, automotive audio amplifiers, tuning speakers, autopilot systems, and voltage control circuits. These potentiometers are designed to be adjustable for high-speed applications with very little ripple voltage.

Working Principle

The FT63ETH104 trimmer potentiometer consists of a variable resistor made up of three terminals: a terminal on the top, a wiper arm which slides up and down, and a base at the bottom. The terminal at the top is connected to the base at a certain resistance, creating a portable voltage between them.
The wiper arm is positioned by a knurled spindle in the middle which rotates, or is moved up and down, and allows a connection to be made with either the top terminal or the base terminal. By controlling the position of the wiper arm, the resistance between the top terminal and the base terminal can be adjusted. When the amount of resistance is altered, the output voltage is changed. This means that a high level of precision can be achieved by the user, allowing for accurate readings and settings.

Conclusion

The FT63ETH104 is a trimmer potentionmeter that has a variety of applications, such as medical and precision instrumentation, automotive audio, and tuning speaker circuits. It consists of a variable resistor with three terminals, and its working principle allows for the user to adjust the resistance between the top and bottom terminals, thereby changing the output voltage. This feature makes the FT63ETH104 suitable for applications that require accurate readings.
