Its pins along with various mounting styles provide versatility in different circuits. It is mainly used for tuning audio amplifiers, controlling volume levels, or adjusting voltage levels for circuits.

Working Principle

The working principle of the 3386F-1-100LF is based on the Wheatstone bridge design. It works by providing a resistive element across two terminals with a current passing through them. As the element is moved along its axis, its resistance is varied, thus changing the voltage output between the two pins. The greater the angle between the two pins, the greater the voltage output. This voltage output then provides a control signal to the switch circuitry controlling the circuit\'s action.

Conclusion

The 3386F-1-100LF trimmer potentiometers are a type of variable resistor used in many different applications. They are durable, reliable, and provide a high degree of control over their resistance. This type of trimmer potentiometer works on the Wheatstone bridge principle, varying the resistance when the shaft is moved. The voltage output is used as a control signal for the switch circuitry governing the circuit’s action.
