Trimmer potentiometers are specialized electronic components used to adjust the control of electrical and electronic circuits. They are composed of three printed circuit board terminals which connect to the circuit, two conductors which carry power to the device, and a component connected to a third terminal which acts as a resistor. Trimmer potentiometers are used in many applications, including audio, video, automotive and consumer electronics.The 72PR20LF, which is manufactured by Vishay Intertechnology, is a trimmer potentiometer designed for precision, low frequency applications. The 72PR20LF is a 10-turn potentiometer, and features an audio taper for improved linearity and an adjustable conductive plastic element for high stability and low temperature coefficient. The construction features anti-rotation, gold-plated tracks for reliable electrical contact, and a polarized housing which is resistive to corrosion and dust. The 72PR20LF has a standard shaft length which is suitable for many applications.The working principle of the 72PR20LF trimmer potentiometer is based on the resistance of the adjustable conductive plastic element. This element consists of two terminals, one connected to a resistor and the other to the variable terminal of the potentiometer. When the shaft of the potentiometer is rotated, the contact between the two conductive plastic elements varies, and the resistance across the terminals adjusts accordingly. This variation in resistance causes a variation in the electrical charge through the circuit, resulting in the adjustable electrical output which can be used to control the function of the circuit.The 72PR20LF trimmer potentiometer is used in many applications, including audio and video equipment, motor control, and remote control of electronic devices. Its adjustable resistor and audio taper provide the user with precise control of the circuit which allows for performance tuning and optimization. In remote control applications, the 72PR20LF can be used to adjust the output voltage of a transmitter and allow for remote control from a distance.The 72PR20LF trimmer potentiometer is a highly reliable, low cost device which is ideal for precision, low frequency, and remote control applications. Its adjustable conductive plastic element and anti-rotation design make it ideal for high stability and long life in applications such as audio and video equipment, motor control, and remote control of electronic devices. Additionally, its 10-turn design and gold-plated contacts provide the user with a reliable and accurate device for precise control and tuning.
