Trimmer Potentiometers

Trimmer potentiometers are components used to control the resistance value of an Electronic source. They give more precise control of resistance values than traditional methods. One of the most popular types of trimmer potentiometers is the ST7EA202, widely used across a range of industries. In this article we will look at the application fields and working principle of the ST7EA202.

Application Fields

The ST7EA202 is a multi-turn variable trimmer potentiometer, with a resistance range of 0 to 2Kohm. It is typically used in applications that require fine tuning or adjustment, such as LCD monitor tuning, TV, radio tuning, controlling circuit signal volume, amplifier, etc. This part is also used in antenna tuners, mobile phone volume adjustment, copiers and other electronic equipment. It can also be used in AC 120V and DC 220V electrical equipment, allowing for adjustments up to 2Kohm. This makes the ST7EA202 suitable for a wide range of applications.

Working Principle

The ST7EA202 is a surface-mount potentiometer which contains a conductive pad. The pad has a movable contact, which is secured by a spring-tensioned arm. This arm is connected to a resistive element, which is linked to the terminals of the device. When the potentiometer is adjusted, the spring-tensioned arm moves the contact over the conductive pad, changing the resistance value of the device. The range of resistance is set by the user, depending on their requirements.

Conclusion

In conclusion, the ST7EA202 is a widely used trimmer potentiometer, capable of precisely controlling resistance values within a range of 0 to 2Kohm. It has a wide variety of applications, including LCD monitor tuning, TV and radio tuning, and AC/DC electrical equipment. Working principle is based on a conductive pad over which a spring-tensioned arm moves, adjusting the resistance value of the device.
