Trimmer Potentiometers

Trimmer potentiometers are widely used in the electronic industry because of their wide range of applications. The 44WR20KLFT7 series are one type of trimmer potentiometer manufactured by Panasonic. These trimmer potentiometers offer great performance and features for various applications.

Applications of 44WR20KLFT7

The 44WR20KLFT7 series are quite versatile, and have a wide range of applications. These include being used as voltage dividers in circuits, as a motor speed control, voltage regulator and amplifier gain control. Additionally, these trimmer potentiometers are also used for variable power supplies, frequency control, and touch screens. All these applications leverage the precision and stability of the 44WR20KLFT7.

Working Principle of 44WR20KLFT7

The 44WR20KLFT7 are 3-terminal devices that use a mechanical motion to control the level of electrical resistance between 2 of its terminals. It has an externally moving element, a and a fixed element b. When the external element is moved, it changes the resistance between the two elements along a designated range. This consequently changes the output voltage across the two elements.

The 44WR20KLFT7 series offer a standard dual-gang construction. This construction also includes a 3-pin connector which simplifies the connection between the potentiometer and other devices. Additionally, these trimmer potentiometers come with an adjustable angle of 60 degrees and a dual shaft construction. This is particularly valuable in applications where adjustment or position is important.

Features and Specifications

The 44WR20KLFT7 series have a maximum resistance value of 200kΩ and a minimum resistance value of 20KΩ. It also offers an adjustable angle of 60±3 degrees for optimization of settings. They also come with a dual-gang construction and power ratings of 0.5 W to 10 W.

Additionally, the 44WR20KLFT7 series feature a rotational torque of 1.8 oz-cm (5.0 gf-cm) and a bounce time of less than 4 msec. Furthermore, they come with a maximum servo life span of 1000 cycles and a maximum operating life of 200,000 cycles. All these features make this series ideal for most applications.

Conclusion

The 44WR20KLFT7 trimmer potentiometers by Panasonic offer superior performance and features for various applications. The adjustable angle, dual shaft construction and 3-pin connector make them ideal for applications where adjustment or position is important. Additionally, these trimmer potentiometers also offer excellent power ratings and operational life span.
