3318F-1-103 Potentiometers, Variable Resistors

Trimmer Potentiometers

Trimmer Potentiometers are used to adjust the settings of electronic components within a circuit. These types of adjustable resistors typically have three terminals, or ‘arms’, each of which are connected to a different voltage or a different resistance. The first arm is connected to the input voltage, the second arm is connected to the output voltage, and the third arm is adjusted using a small control knob.

3318F-1-103 is a trimmer potentiometer specifically designed for use in computer-based applications. It features three pins for connecting power supply, output voltage, and adjustment terminal and a small control knob on top for adjusting the resistance of the pot. It is a very compact device, measuring just 0.4” wide and 0.4” high. It comes in two different resistance ranges: from 1k ohms to 10k ohms and from 10k ohms to 100k ohms. However, it does not include a built-in power supply, meaning that the user must provide their own power supply for it to work properly.

The 3318F-1-103 is mainly used in audio and video systems. It is typically used to adjust the volume of an audio system, the brightness of an LCD screen, or the contrast of a video screen. It can also be used to adjust the gain of an amplifier or the frequency response of a speaker system. Additionally, it is widely used as an adjustable voltage divider for measuring signals from different sources.

The working principle of the 3318F-1-103 trimmer potentiometer is quite simple. When the control knob is turned, the resistance between the two outer terminals changes, and the voltage at the output terminal is altered accordingly. For example, if the resistance between the two outer terminals is altered from 0K ohms to 10K ohms, the voltage at the output terminal will be divided by 10. This is because the current flowing through the resistance (I = V/R), which is determined by the resistance (R) between the two terminals, is halved.

The 3318F-1-103 trimmer potentiometer is a very versatile and useful device. It is capable of providing precise control over a wide range of electrical parameters and can be used in a variety of applications. Furthermore, it is extremely compact and easy to use.
