Introduction

Trimmer Potentiometers are widely used components in the electronics industry, taking advantage of their adjustable characteristics in a wide range of applications. The 3386F-1-303 trimmer is an example of this type of component, featuring adjustable resistance within a small form factor. In this paper, we will examine the field of application and working principle of this device.

Application Field of the 3386F-1-303

The 3386F-1-303 is a surface mount trimmer potentiometer, measuring just 7.9 millimeters tall and 7.0 millimeters in width. As a result, it\'s ideally suited for applications where space is at a premium. It\'s typically used as part of a circuit for controlling electric current, typically between 1kOhm and 20kOhm, making it suitable for use in audio and radio frequency receivers.The 3386F-1-303 is robust and reliable, making it suitable for a range of demanding applications. It performs particularly well in industrial automation systems, such as robotics, aiding the accuracy of electrical controls within these machines.

Working Principle of the 3386F-1-303

The 3386F-1-303 operates on the principle of a variable resistor, changing its resistance in order to control electric current. The device consists of three metal contacts – the wiper, the first terminal and the second terminal. The resistance between the wiper and contacts varies based on the position of the wiper, with the resistance increasing or decreasing depending on the direction of the wiper\'s movement.The resistance of the 3386F-1-303 trimmer is adjustable from 1kOhm to 20kOhm, launched for rotation an angular displacement of 1 turn in either direction. This feature reduces the amount of time required to test and calibrate circuits, as well as reducing the cost of these procedures. It also ensures accuracy and repeatability, as manually adjusting the potentiometer will provide the same result each time.

Conclusion

The 3386F-1-303 is a surface mount trimmer potentiometer, designed to enable accurate and repeatable control of electric current. The device features adjustable resistance, providing a range of 1kOhm to 20kOhm, launched for rotation an angular displacement of 1 turn in either direction. This makes it suitable for use in applications where space is at a premium, such as industrial automation systems.
