IntroductionTrimmer potentiometers, or trimmer pots, are a small variable resistor used to vary voltage and current in electronic circuits. Although they are often used to control things such as the brightness of an LCD display, they can also be used to control a variety of other settings, including audio output or the speed of a motor. One type of trimmer pot is the 3386B-1-205, which can be used for a variety of applications and has different working principles.Application fieldThe 3386B-1-205 trimmer pot is widely used in electronic circuits and is especially useful for setting precise levels in applications such as power supplies, amplifiers, and attenuators. It can also be used to adjust the resonance of a crystal oscillator or to set the bias of a transistor. The potentiometer is also ideal for settings that require frequent adjustment, as it allows for easy and precise adjustment. Working PrincipleThe 3386B-1-205 trimmer pot works by allowing the user to adjust the amount of resistance in the circuit. This is done by rotating the adjustment screw, which moves a wiper that changes the resistance. Although this type of pot has three terminals, it is actually a two-terminal device since the third terminal is simply connected to the wiper. The two outer terminals can be either connected to a power source or to two nodes in a circuit, while the wiper is connected to a third node in the circuit. By varying the resistance of the pot, the voltage or current in the circuit can be adjusted. ConclusionThe 3386B-1-205 trimmer pot is a useful and versatile device that can be used to adjust voltage and current levels in a range of applications. It works by altering the amount of resistance in a circuit, allowing the user to easily adjust the voltage or current in the circuit. The 3386B-1-205 pot is popular in electronics design and is often used in applications that require precise adjustment of voltage or current.
