Trimmer Potentiometers provide a means to precisely adjust the resistance of an electric circuit. The 3314J-1-223E specifically is a resistive trimming device designed to be used in high volume consumer products. The adjustable range is from 0 to 5 kΩ with a full rotation of 3.0 ± 0.2 kΩ for applications including audio and video, telecommunications, industrial and other areas. It is constructed from both alumina and plastic materials making it both lightweight and very reliable.

The 3314J-1-223E is a three-terminal device, two of which are the adjustment terminals with the third connected to the wiper contact. The adjustment terminals are divided into two parts, the terminals of the wiper contact and the adjustable component, which is housed in a metal footplate. The adjustable component operates as a resistor whose resistance is adjustable by rotating the dial.

The adjustment device is made up of a pair of oppositely wound coils of wire which form the “potentiometer” element when a voltage is applied to them. When the voltage is zero, the coil of wire balances perfectly, however, when a voltage is applied, the coil starts to move. This movement of the coil then causes the resistance of the potentiometer to increase or decrease depending on the direction of the applied voltage.

The 3314J-1-223E trimmer potentiometer provides high quality, reliable performance even in the most demanding applications where accuracy is a must. It features a precision trimming circuit which allows for precise adjustment of resistance over the complete range of the adjustable component without any additional parts or components being needed. It is designed to provide maximum resistance stability and to provide performance that is consistently reliable in temperature, shock and vibration conditions.

The 3314J-1-223E trimmer potentiometer provides a simple and cost effective way to adjust resistance in electric circuits without the need for complex or expensive components. It is especially suited for high volume consumer products where reliability is essential. By adjusting the resistance of the potentiometer, a variety of different adjustable circuit parameters can be realized which can then be used to tailor the performance of the circuit to the specific requirements of the application.
