Trimmer Potentiometers: PV37P203A01B00 application field and working principle

Trimmer potentiometers, also called trim pots, are a specific type of variable resistors which are widely used to fine-tune electrical devices. Commonly used in circuit boards, these components reduce the need for manual adjustments while improving device performance. One such example is the PV37P203A01B00 trimmer potentiometer manufactured by Bourns.

General Overview

The PV37P203A01B00 is a multiturn (cermet) trimmer that measures 6mm in diameter, is 18.8mm long, and weighs 1.2g. Each potentiometer is typically rated for 100,000 life cycles and a 50ms response time. Inside the component is a conductive element attached to two electrodes that is surrounded by a ceramic or plastic ring. This conductive element moves across the electrodes, connecting them and changing the resistance value.

Applications

Trimmer Potentiometers are used in a variety of applications, such as audio and video equipment, home appliances, automotive electronics, and industrial automation. The PV37P203A01B00 is particularly suitable for industrial automation applications, including factory plant monitoring systems, calibration systems, power supplies, and motor speed control.

Working Principle

Trimmer potentiometers work on a different principle than other types of variable resistors. Unlike a standard potentiometer, which is adjusted manually, a trimmer pot is adjusted electronically using an external voltage. This voltage is applied to two terminals called “taps”, which are connected to the electrodes surrounding the conductive element. When the voltage is applied to the taps, it creates a magnetic field that is applied to the conductive element, causing it to move across the electrodes and change the resistance. The voltage applied to the taps determines the amount of resistance that is produced.

Conclusion

The PV37P203A01B00 is a multiturn trimmer potentiometer manufactured by Bourns. It is typically used in industrial automation applications, such as factory plant monitoring systems, calibration systems, power supplies, and motor speed control. This component works on a different principle than other types of variable resistors, as it is adjusted electronically instead of manually. By applying a voltage to the two taps connected to the electrodes surrounding the conductive element, a magnetic field is created that causes the conductive element to move across the electrodes and change the resistance.
