Introduction

Trimmer potentiometers are potentiometers that utilize adjustable trimmable resistors in place of the valves in a traditional potentiometer, and are used for tight tolerance, repeatable adjustment of essential parameters, providing reliable feedback and dynamic control to many electronic systems. 3386J-1-502LF is one of the products of this kind, and it is specially used in circuit board applications. This article will explain the application field and working principle of 3386J-1-502LF.

Application Field

3386J-1-502LF is widely applied to various circuits in electronic applications. Generally speaking, it mainly works in the audio applications such as commercial amplifier, television set, car radio, radio receiver, stereo set and woofers, etc. Wherever accurate adjustment of resistance is required and the end-to-end tolerance is tight, 3386J-1-502LF is an ideal choice. Additionally, 3386J-1-502LF also finds its broad application in circuit boards for a variety of applications like medical equipment, scientific instruments, audio/video equipment, computer peripherals and instrumentation, in which it works as a reliable fine-tuning device to adjust sensitive electronic parameters.

Working Principle

3386J-1-502LF is a potentiometer whose resistance is adjustable by mechanically turning the shaft. Its working principle essentially mirrors that of other potentiometers. When the slider of a 3386J-1-502LF is rotated, the resistance between the ends of the terminals changes, creating a voltage divider when an external voltage is applied. Potentiometers adjust current flow by controlling the amount of resistance provided (or subtracted from an otherwise closed circuit) to the flow of electricity. The slider of a 3386J-1-502LF is used to regulate this resistance. As the user turns the shaft counterclockwise, the slider traverses down the element, increasing resistance and further restricting the current.

Conclusion

As a widely-used trimmer potentiometer, 3386J-1-502LF is mainly applied to audio applications and circuit boards for a variety of applications. The working principle of 3386J-1-502LF is also similar to other potentiometers, in that it is used to adjust current flow by controlling the amount of resistance provided (or subtracted from an otherwise closed circuit) to the flow of electricity.
