Trimmer Potentiometers are an essential component in many electronic systems. ST42ETH200 is a very versatile device that can be used in multiple applications. This article will discuss its application field and working principle.

Applications of ST42ETH200

The ST42ETH200 is a two-terminal trimmer potentiometer that is frequently used in adjustable voltage and current regulation applications. It is manufactured by STMicroelectronics, and it has excellent features such as thermal stability, small footprint, and reliability. The ST42ETH200 provides a wide range of resistance values, from 10 Ω to 200 Ω, allowing for precise adjustment of the electrical parameters.

It can be used in power supplies in combination with a current sensing resistor to detect the output voltage and control the power supply\'s regulation. It can also be used in signal conditioning circuits, and in audio applications to adjust the signal gain. Additionally, the ST42ETH200 can be used as an adjustable bias in transistors and LEDs, allowing for fine-tuning of their performance.

Working Principle of ST42ETH200

The ST42ETH200 is a two-terminal trimmer potentiometer that uses surface mount technology for mounting. It is constructed from a ceramic substrate and uses a spiral conductive track that is made from a nickel-plated conductive metal. The resistance of the device is adjustable by turning a small screw located on the top of the device.

When the screw is turned, it creates a lever that moves the electrical contacts of the conductive tracks, resulting in a change in resistance. The total resistance value of the device is determined by the length of the track, as well as the resistance of the material used to make the track.

The ST42ETH200 has a low temperature coefficient of resistance, meaning that the resistance of the device does not change much when the temperature changes. This makes it ideal for use in temperature sensitive applications, such as power supplies and audio applications.

Conclusion

The ST42ETH200 is a highly versatile trimmer potentiometer that can be used in multiple applications. Its low temperature coefficient makes it well-suited for use in sensitive applications, such as audio and power supplies. Additionally, it is easy to adjust the resistance value with the adjustable screw located on the device. All these features make the ST42ETH200 an attractive choice for many applications.
