Trimmer Potentiometers

Trimmer Potentiometers are adjustable resistors which are most commonly used to control equalization levels in audio equipment, amplifier systems, and other electronic solutions which require precise adjustable levels of resistance. The most common form of trimmer potentiometer is the PV37Y200A01B00, which is a three-terminal adjustable device consisting of a resistive element, high-precision adjustment screw and a knob.

Application Field

The PV37Y200A01B00 is designed for applications which require fine-tuning and higher precision adjustments than a traditional potentiometer. It is ideal for use in computer monitor/televisions sets, optical audio equipment, printers, copying machines and other equalization applications. Moreover, the element of this device ensures reliable operation over temperature ranges from -55°C to 125°C, and a power rating of 0.2W at 70°C.

Working Principle

As a three-terminal device, the PV37Y200A01B00 features two fixed terminals contact points and one adjustable terminal. When the adjustment screw is rotated, a variable resistance is created between the two fixed terminals, controlled by the rotation of the screw. This principle allows the device to provide a reproducible, adjustable resistance value in a broad range that can be finely tweaked. Furthermore, since the device is a three-terminal design, the output voltage will remain constant even when the resistance value changes.

These features make the PV37Y200A01B00 an ideal device for precise resistance control within a wide range of operations. This type of potentiometer is also popular because it has a high stability and precision of electrical performance, as well as excellent noise immunity for minimal signal interference.

Conclusion

The PV37Y200A01B00 is an adjustable device most commonly used in audio and equalization applications. It consists of a resistive element, high-precision adjustment screw and a knob, and offers reliable operation across a wide temperature range. This device has a three-terminal design, allowing it to provide reproducible, adjustable resistance values in a broad range with high stability and precision. Overall, the PV37Y200A01B00 is an excellent choice for applications which require fine-tuning and higher precision adjustments.
