89WR2KLF

Trimmer Potentiometers

Potentiometers are commonly used to control the electrical output of an electronic device by varying the resistance within the circuit. Among these, trimmer potentiometers allow for adjustment of the resistance when the device is in operation. The 89WR2KLF is one of the most widely utilized trimmer variants for such applications.

89WR2KLF Overview

The 89WR2KLF is a single-turn miniature trimmer comprising of a resistor element with an adjustable wiper. It is built upon a three-terminal mounting system, with the wiper terminal set in the center, allowing for easier mechanical adjustments. This trimmer model is designed for use in through-hole, SMT, or printed circuit boards and offers reliable performance in a variety of applications.

89WR2KLF Application Field

Trimmer potentiometers are commonly seen in control circuits, and the 89WR2KLF is no exception. This trimmer model is specifically designed to be used in precision-sensing systems such as motor speed controllers, heater control circuits, and switching circuit applications. Additionally, it is frequently used in amplifier circuits due to its versatility and accurate control of the resistance.

89WR2KLF Working Principle

The 89WR2KLF works by passing a small current through a fixed resistor element. This circuit is connected to the three terminals of the 89WR2KLF and a voltage is applied across the two outer terminals of the trimmer. The wiper terminal is connected to the circuit output and adjusts the relative resistance between the two outer terminals, allowing for accurate control of the electrical output of the device.

Conclusion

The 89WR2KLF is a miniature trimmer potentiometer designed for use in precision-sensing circuits. Its adjustable wiper and three-terminal mounting system facilitate easier mechanical adjustments, while its range of application fields and reliable performance make it one of the most popular trimmer variants.
