Trimmer Potentiometers

A trimmer potentiometer is a type of adjustable resistor with a small form factor, which has three terminals (plugs) located on the bottom case and three pins connected to a track on the top of the case. The PV32N202A01B00 is a two-channel, digital trimmer potentiometer, with a nominal resistance of 200 Ω, and a typical variation of +6/-3%.

Application Field of PV32N202A01B00

The PV32N202A01B00 is widely used in various fields such as telecommunications and consumer electronics. It is found in devices such as mobile phones, digital cameras, laptop computers, handheld gaming consoles, and car navigation systems. Furthermore, the PV32N202A01B00 is also used in medical devices like insulin pumps and ventilators.

Working Principle of PV32N202A01B00

The working of PV32N202A01B00 a trimmer potentiometer is based on the principle of the electrical resistance. The resistance of a trimmer potentiometer is made up of three separate metal tracks. These tracks contain an adjustable resistor, and the resistance is determined by the amount of contact between the metal tracks and the resistors. The adjustment of the resistance is accomplished by turning the top portion of the potentiometer. This rotates the track against the resistors, causing the resistance to increase or decrease accordingly.

The PV32N202A01B00 can also be adjusted with an external voltage, due to its low resistance values. Applying a voltage to the tolerance pins (pins 2 and 3) will cause the resistance to increase or decrease linearly with the applied voltage, allowing for different voltage sensitivities.

The adjustment of the PV32N202A01B00 is done by a digital variable knob located at the center of the potentiometer. The knob is connected to a digital resistance chip that can be calibrated to the desired resistance value or read back the resistance value, along with a voltage output.

Apart from being an adjustable resistor, the PV32N202A01B00 can be used in precision electronic circuits where precise adjustment is necessary. This is because it has a low temperature coefficient that allows for accurate adjustment of the resistance with a minimal effect on the actual resistance.

Conclusion

The PV32N202A01B00 is a trimmer potentiometer with a nominal resistance of 200Ω and a typical variation of +6/-3%. This trimmer potentiometer is found in various fields of application such as telecommunications and consumer electronics, medical devices, and precision electronics. It is adjusted by a digital variable knob, and its resistance can be changed either manually or by applying an external voltage.
