Trimmer Potentiometers

Trimmer potentiometers, commonly referred to as “trim pots”, are small variable resistors used to adjust settings for all kinds of electronics components and circuits. Trim pots come in a range of different shapes and sizes, and are usually mounted on a substrate or printed circuit board (PCB). The most common types of trimmer potentiometers are cermet trim pots, conductive plastic trim pots, and wirewound trim pots. On a PCB, trimmer potentiometers typically have three legs (terminals). The middle terminal is connected to the resistor wiper which slides along the resistor track and can be adjusted to any point on it. The other two terminals are connected to the ends of the resistor track and are used as the electric terminals for connecting to the circuit. Trimmers are usually adjusted with a small screwdriver and are used for fine-tuning components or settings in a circuit.The 93PR20LF is a type of trimmer potentiometer used in a wide range of applications. It is a single-turn (resistor turns) trimmer, meaning that the wiper is only able to travel through one full rotation on the resistor track. The 93PR20LF is also fairly small, with a dimension of 20mm x 10mm x 6.5mm, making it perfect for applications where space is limited.The 93PR20LF trim pot is commonly used in various applications due to its small size and flexibility. These applications include amplifier gain control, LED brightness control, frequency adjustment, voltage reference, mechanical sensing, and adjustable filters. It is also used in combination with other types of sensors to improve the accuracy of sensing data.The working principle of the 93PR20LF is quite simple. When a voltage is supplied to the two external terminals of the trimmer, it generates a potential difference across the resistor. The resistance value is adjusted by moving the wiper along the resistor track which changes the potential difference. In summary, the 93PR20LF is a type of trimmer potentiometer that is used in a wide range of applications, thanks to its small size and flexibility. It is most commonly used for amplifier gain control, LED brightness control, frequency adjustment, voltage reference, mechanical sensing, and adjustable filters. The working principle of the 93PR20LF is to adjust the resistance value by moving the wiper along the resistor track which changes the potential difference.
