3296Z-1-204LF

Trimmer Potentiometers

A trimmer potentiometer, or trim pot, is a small variable resistor that is used to adjust the current or voltage flow in a circuit. The 3296Z-1-204LF is a trimmer potentiometer specifically designed for applications where it needs to be mounted in a PCB as there are four mounting pins. It has a resistive element with three external terminals, and the resistive element is usually a coiled wire.

Application Field and Working Principle

The 3296Z-1-204LF is a very versatile trimmer potentiometer that can be used in a variety of applications. It is used in radio and television receivers, audio equipment, test and measurement equipment, medical equipment, and robotics. It is also used as an adjustable voltage regulator in AC/DC power supplies.

The 3296Z-1-204LF works on the principle of resistance. The resistive element is made up of a coiled wire and it works just like a potentiometer. When a voltage is applied to the two outer terminals of the resistor, it induces a current flow through the coil. This current flow induces a voltage drop across the coil, which results in a resistance value between the two terminals. The middle terminal of the resistor is used to adjust the resistance value by adjusting the position of the coiled wire.

The adjustment of the potentiometer is achieved by rotating the screw mechanism located at the center of the component. This rotary motion moves the contact point of the resistive element, thus changing the overall resistance of the component. The resistance value can be adjusted from 0 to 10,000 ohms, allowing for precise control of current or voltage in the circuit.

The 3296Z-1-204LF is a very useful component in many applications. It is easy to install, and its small size makes it suitable for use in compact circuits. The adjustable resistive value also allows for precise control in a wide range of applications, making it a very versatile and reliable component.
