Trimmer Potentiometers

The 3269P-1-201LF is a small trimmer potentiometer, which is commonly used for adjusting functions in electronic circuits. This device consists of three terminals, two outer terminals connected to the element end-point resistors, and one centrally positioned terminal for adjustment.

Applications

Trimmer potentiometers are versatile and can be used in a range of applications. Considering its small size, the 3269P-1-201LF is often used for fine-tuning functions and adjusting audio systems. It is also commonly seen in airplanes and boats, as it is ideal for providing static or dynamic adjustments in tight spaces. Additionally, it can be used as a rheostat to regulate the flow of current or to vary voltage drop across a circuit.

Working Principle

Dependent on the application, trimmer potentiometers can be connected as a variable resistor or rheostat. An example of a variable resistor would be using it as a volume control on a speaker system. In this application, the two outer terminals would be connected to the power supply and the wiper terminal, which is the adjustable contact point to the resistive element, would then be connected to the speaker. When using the 3269P-1-201LF as a rheostat, the two outer terminals would be used as A and B terminals, and the wiper terminal would be the ground connection. Depending on which direction you turn the adjustment knob, this will increase or decrease the current running through the circuit.

Conclusion

The 3269P-1-201LF trimmer potentiometer is an excellent component to use when needing to make minor adjustments to electronic circuits. It is small in size, yet offers a great level of precision and reliable performance. Additionally, it can be used as a variable resistor or rheostat, depending on the application.
