Trimmer Potentiometers

Trimmer potentiometers, also known as semi-variable potentiometers, basically use in the circuit that does not need to adjust often, if the voltage in color TV switch power supply adjusts potentiometer. The fine-tuning potentiometer has three pins and usually has an adjustment hole on it. The resistance can be adjusted by inserting a screwdriver into the adjustment hole and rotating it. The fine-tuning potentiometer plays an significant role in the power amplifier circuit, which is mainly used for frequency, amplification gain, determination of partial voltage ratio or reference voltage adjustment.
