Trimmer potentiometers, also known as trimpots, are three-terminal resistors with a sliding or rotating contact that forms an adjustable voltage divider. The 72XR200LF is a trimmer potentiometer specifically made for use in high temperature applications. It offers greater stability and durability than other trimmers due to its higher heat resistance and construction materials. This trimmer potentiometer also features a low noise design and does not require contact lubricant.

Application Field: The 72XR200LF trimmer potentiometer is suitable for use in a wide range of high temperature applications, such as automobile dashboard settings, medical medical applications, fuel control in aircraft, etc. This device also finds application in laboratory equipment used in testing and calibration. The 72XR200LF is also suitable for automotive sensors, audio/video equipment, measuring instruments, automation systems, and other similar applications.

Working Principle: The working principle of a trimmer potentiometer is based on a voltage divider. In a trimmer potentiometer, the variable contact forms a resistive bridge between two fixed contacts. The output voltage of the divider depends on the position of the variable contact. When the variable contact is moved toward the contact at the lower end of the divider, the output voltage increases. Conversely, when the variable contact is moved toward the contact at the upper end of the divider, the output voltage decreases. This adjustment allows signals passing through the potentiometer to be altered or adjusted.

The 72XR200LF trimmer potentiometer has an operating temperature range of -55 °C to +155 °C with a power rating of 0.05W. It is available with contact resistance values of 50 ohms to 500 ohms and features a ceramic bushing for increased durability.

The 72XR200LF trimmer potentiometer is an ideal device for use in high temperature applications. Its low noise design makes it suitable for use in audio/video equipment and other applications requiring a low noise solution. This trimmer potentiometer also has a ceramic bushing for increased durability and a wider operating temperature range than other trimmers.
