The 3386C-1-101LF Trimmer Potentiometer is a two-terminal, linear resistance device. It’s a popular choice for precision voltage divider networks, due to its low cost and small size.

Application Field of 3386C-1-101LF

The 3386C-1-101LF Trimmer Potentiometer is primarily used in low-power applications. It is often found in oscillators, amplifiers, signal generators, and precision voltage divider networks. This trimmer is suitable for voltage and current regulation, feedback applications, and to maintain accurate circuit conditions. In addition, it is used in auto-tuning devices, as a variable resistor to adjust impedance matching circuits, and in isolated power supplies.

Working Principle of 3386C-1-101LF

The 3386C-1-101LF Trimmer Potentiometer is made up of three contact terminals: two fixed terminals for the wiper arm and a sliding third terminal, called the wiper, that moves along the resistance element. The resistance between the two fixed terminals is adjustable by turning the wiper arm. As the wiper is rotated, its contact point moves along the resistive element, increasing or decreasing the resistance between the two fixed terminals. A voltage source is connected to the two fixed terminals and a voltage measure is connected to the wiper. When the wiper is rotated, the measure voltage will be proportional to the resistance. According to Ohm’s law, the current that flows through the trimmer is also proportional to the wiper position.

Conclusion

The 3386C-1-101LF Trimmer Potentiometer is a two-terminal, linear resistance device with a wide range of applications. It is suitable for precision voltage and current regulation, feedback applications, and impedance matching circuits. This trimmer operates based on Ohm’s law and adjusting the resistance across the two fixed terminals by turning the wiper arm. For its low cost and small size, the 3386C-1-101LF is a popular choice for these kinds of applications.
