Trimmer Potentiometers

Trimmer Potentiometers, also known as variable resistors are used in a variety of applications for controlling and adjusting signals and voltages. One such trimmer potentiometer is the 3313J-2-104E and, in this article, we will discuss its application field and working principle.

Application Field of 3313J-2-104E

The 3313J-2-104E is a trimmer potentiometer, which finds its application in audio and video equipment such as amplifiers, tuners and preamplifiers. It is also used in instruments like oscilloscopes and multimeters. The 3313J-2-104E provides precise voltage adjustment in these systems and instruments. This trimmer potentiometer also finds its use in the manufacturing industry for controlling the flow and rate of materials in automated systems.

Working Principle of 3313J-2-104E

The 3313J-2-104E is a resiliently mounted trimmer potentiometer. It has a gold-plated contact knob driven by a reel that follows a spiral track on a phenolic structure, surrounded by a conductive material. This design enables the contact knob to remain in a fixed position when displaced from its static position. The contact knob is capable of adjusting resistance values from 0 ohms to around 64.5 kilo-ohms. The internal circuit also has two fixed resistances which are used to select the maximum and minimum values of resistance. The potentiometer also has a printed circuit board connecting the fixed resistors with the terminal contacts.
