43C120K

Rotary Potentiometers, Rheostats

The 43C120K is a precise, reliable, and economical rotary potentiometer that is available in miniature plastic packages. It is a three-terminal device comprising a pivot shaft, a wiper, and a resistive element. 43C120K provides the user with a wide range of applications and is available in a variety of styles, sizes, and options.

Application Field

43C120K\'s 3-terminal configuration makes it suitable for a wide variety of electronic applications such as signal conditioning, amplification, and switching. As its name implies, this potentiometer is designed to be used in many different fields. Its applications range from controlling audio levels to adjusting motor speed and controlling the temperature of various systems.

Working Principle

The potentiometer consists of a sliding element, called the wiper, which resides between two resistive elements. When the wiper is moved along the resistance element, a variable voltage or resistance is developed between the wiper and one of the termination leads. The voltage or resistance developed across the terminals can be varied by adjusting the rotor shaft. In this regard, 43C120K can serve as a precision linear voltage divider and rheostat.

As with all potentiometers, the 43C120K enables users to make precise adjustments in the range of signal strengths. The device has an extended linearity over its full rotation of 300 degrees. With its built-in wiper contact protection, the 43C120K is well suited for any electronic application where reliable performance is a key requirement.

In addition to its obvious benefits, the 43C120K can be used in numerous other applications as well. It can be used to adjust audio level and gain, adjust motor speed, adjust temperature control systems, calibrate laboratory instruments, and as a rheostat for controlling electrical power. All of these applications and more make the 43C120K an invaluable device to any electronic user.

Conclusion

The 43C120K rotary potentiometer is a very useful and versatile device that is sure to see use in a variety of industries and applications. Its three-terminal configuration and consistent operation make it a reliable choice for any application. With its extensive list of uses and its extended linearity over its full rotation, the 43C120K is sure to remain a favorite choice among electronic users for years to come.
