Trimmer Potentiometers

Trimmer potentiometers are adjustable resistors that are designed to help calibrate, balance, or bias circuit elements and parameters within a system. They are of small size, lightweight, and are capable of being adjusted very precisely over a short range. A trimmer potentiometer, like most other resistors, is composed of a resistive element, a rotor, terminals, and a body, which is used to mount the potentiometer and secure all the parts in place.

82MR1MEGLF Application Field and Working Principle

The 82MR1MEGLF is a trimmer potentiometer that is commonly used in applications such as test and measurement, industrial control, medical device, audio amplifier, and power supplies. The potentiometer has three terminals, two of which are connected to the rotatable element, with the third one being connected to the resistive element. When the rotor spins, it changes the resistance through these two terminals. The third terminal is not connected to the rotatable element but the resistance of the whole device varies depending on the rotor’s position.

The 82MR1MEGLF is very useful in applications requiring precise adjustments. It can be used to adjust the frequency of oscillators, set the gain of an amplifier, set the set point in a temperature controller, or any other application requiring precise adjustments. It is very reliable and accurate and can be adjusted without having to disconnect any wires. It is also very compact and lightweight and can be easily mounted in a system.

The 82MR1MEGLF also has a wide operating temperature range of -55°C to 125°C. This makes it ideal for applications in harsh or extreme environments. It also features a low temperature coefficient of approximately 15PPM/°C, which allows it to maintain a constant resistance even when the temperature changes.

The 82MR1MEGLF is also very rugged and resistant to vibration and shock. This makes it suitable for use in applications such as aerospace, automotive, and military. It is also easy to install and can be mounted with screws, clips, or adhesives.

In summary, the 82MR1MEGLF trimmer potentiometer is a reliable and accurate device that can be used for a wide variety of applications. Its compact size and resistance to environmental factors makes it ideal for use in harsh or extreme environments. It also has a wide operating temperature range and low temperature coefficient, making it suitable for use in aerospace, automotive, and military applications.
