Trimmer Potentiometers

EVN-D2AA03B25 Application Field and Working Principle

Trimmer potentiometers, also known as variable resistors or trimmers, are small devices that are often used to adjust voltages or other electrical signals in circuits. The EVN-D2AA03B25 is a trimmer potentiometer manufactured by Everswitch. This product is used in a wide variety of applications, including audio equipment, computer systems, medical equipment, and more.The EVN-D2AA03B25 is a 3-terminal device with a single potentiometer that is adjusted using a screwdriver. It has a three-pin form factor with two fixed terminals and one adjustable terminal which can be adjusted to achieve various levels of resistance. The device is small and can fit in areas with limited space. It is also able to withstand temperatures from -40°C to +85°C, making it suitable for a variety of applications.The potentiometer works by adjusting the resistance between two fixed terminals. The resistance between the two fixed terminals is determined by the position of the adjustable terminal. When the adjustable terminal is moved further away from the other two terminals, the resistance will increase. Conversely, when the adjustable terminal is moved closer, the resistance will decrease. This effectively allows the users to adjust the voltage or other signals as desired.As these potentiometers are widely used in different applications, they require testing and calibration to ensure optimal conditions. Calibration is typically done by using a multimeter to measure the resistance between the two fixed points. The multimeter should be set to the desired voltage range, and the resistance should be measured at various points of the adjustment range. The user can then compare the readings to ensure accuracy and trace any errors that may occur.In conclusion, the EVN-D2AA03B25 is a trimmer potentiometer manufactured by Everswitch. This product is suitable for a wide range of applications and can adjust voltages or other electrical signals through the adjusting of its adjustable terminal. The resistance between the two fixed terminals is determined by the position of the third terminal. Finally, these potentiometers need to be calibrated to ensure the desired results.
