Trimmer Potentiometers

The 3386U-1-103LF is a type of trimmer potentiometer specifically designed to provide a finite electrical resistance value in between two terminals. It is capable of effectively adjusting the direct current (DC) circuit parameters to set the desired output of an electronic circuit. Trimmer potentiometers, such as the 3386U-1-103LF, enable engineers to precisely adjust the resistance value of an electrical circuit by turning the shaft of the potentiometer with a suitable screwdriver.

Applications

Trimmer potentiometers, such as the 3386U-1-103LF, find extensive use in various applications. It is widely used in printed circuit boards (PCBs) to adjust parameters, such as frequency, phase, and sensitivity. The 3386U-1-103LF is also used in the calibration of voltage loops and volume controls in amplifiers. Other applications include its use in frequency adjustment of television sets, air conditioners, and stereo systems.

Working Principle

The 3386U-1-103LF trimmer potentiometer consists of three terminals surrounded by a conducting coil and an adjustable armature. When the shaft of the trimmer potentiometer is rotated, the position of the armature within the coil can be changed, thereby altering the electrical resistance between the terminals. By precisely adjusting the armature\'s position, an engineer can obtain the exact resistance value required for a particular circuit.

The 3386U-1-103LF trimmer potentiometer is designed to operate within an affordable voltage range. It is also compatible with most printed circuits board designs. The trimmer also provides accurate linear characteristics and reasonable temperature coefficients. Furthermore, the 3386U-1-103LF is highly resistant to stress, heat, humidity, acids, oils, and other corrosive elements that can be encountered in many electronic circuits.

Summary

The 3386U-1-103LF is a type of trimmer potentiometer designed to precisely adjust the resistance values of a DC circuit. This trimmer is useful in various applications, including printed circuit boards, frequency adjustment, volume controls, and voltage loops. It consists of three terminals and a conducting coil with an adjustable armature. When the armature is moved, the resistance value of the circuit can be adjusted with precision.
