Trimmer potentiometers are versatile control devices used in a wide range of applications. ST4ETA501 is one of the most popular and widely used trimmer potentiometers today. This article will explain its application field and its working principle.

Trimmer potentiometers are mainly used for adjusting electrical characteristics of circuits such as resistance, filter coefficients, frequency, and time. ST4ETA501 can be used to adjust resistance, frequency response, and filter coefficients. When used to adjust resistance, the ST4ETA501 adjusts the degree of resistance within the circuit.

ST4ETA501 is also beneficial in frequency response adjustments. It can be used to adjust the frequency response up or down depending on the desired outcome. Lastly, it can be used to adjust the filter coefficients. It can be used to adjust the cut-off frequencies of low-pass, high-pass and band-pass filters. All of these applications make the ST4ETA501 a go-to device for all of your trimmer adjustment needs.

The working principle of the ST4ETA501 is relatively simple. It consists of a resistance element made up of resistive material connected between two terminals. This element is connected to a third terminal called the adjuster. It is this terminal that is used to adjust the resistance between the two terminals. As the adjuster is moved, the resistance is increased or decreased, thus allowing us to adjust the parameters of the circuit.

The ST4ETA501 is designed as an adjustable three-terminal resistor. It has a total overall resistance of 2 to 22 kΩ, with an adjustable resistance range between 0.8 and 22 kΩ. The adjustment knob of the ST4ETA501 provides a manual adjustment range of 20%, which can be used to adjust the resistance of the device.

In conclusion, the ST4ETA501 is a very popular and useful trimmer potentiometer. It has a wide variety of applications, including resistance, frequency response, and filter coefficient adjustment. its working principle is relatively simple, consisting of a resistance element connected between two terminals, along with a third terminal used to regulate the resistance. In addition, it has an adjustable resistance range between 0.8 and 22 kΩ, with a 20% manual adjustment range.
