Rotary Potentiometers, Rheostats, and the 43C11000 Application Field and Working Principle

When it comes to the application field and working principle of the 43C11000, the device falls into the family of rotation potentiometers and rheostats - each of which has their own purpose and functions.

A potentiometer is an electrical component with a high degree of resistance. What distinguishes a potentiometer from other variable resistors is that it can be adjusted using a wiper that is connected to a rotary element, like a knob or dial. Potentiometers have three terminals on the back. The rotating unit is connected to the middle pin, while the left and right pins are the end terminals. As the knob of the potentiometer is turned, the wiper slides along the resistance, giving the user a way to precisely change or adjust the resistance.

The 43C11000 from Murata is a single turn combination of a potentiometer and a rheostat. This type of device is known as a concurrent or drag type potentiometer. A drag type potentiometer is basically two potentiometers in one package, the difference being that the two potentiometers are connected to the same wiper. This provides the user with an increase in resolution and gain. The 43C11000 is a 10-turn rotary potentiometer, the current rating of the device is 1 milliamp and the total resistance is 37.5 kOhms.

When it comes to the working principle of the 43C11000, the device uses a particular type of wiper, known as a drag type wiper. This type of wiper is connected to two separate resistance elements, so that one wiper can move in response to the movement of a single rotary element. This feature helps the user to fine tune the resistance in small increments, which allows for accurate control of the device resistance. With this type of wiper, the 43C11000 can provide consistent and reliable adjustment.

The applications of the 43C11000 from Murata is vast, which range from manual adjustment and linear measurement in instruments, to precision adjustment of signal levels in audio and other electronic equipment. The 43C11000 is well suited for use in high-end audio equipment, as it has a high degree of resolution and accuracy. In addition, the 43C11000 can also be used as an attenuator or as a low-power variable voltage divider. Moreover, due to its wide range of applications, the device is often used in industries to measure current, voltage, or a physical parameter such as speed or position.

In conclusion, the 43C11000 from Murata is a 10-turn rotary potentiometer and a rheostat in a single package, filled with a drag type wiper. With its high resolution and accuracy, the 43C11000 is an ideal component for fine adjustments needed in precision instruments, audio and other electronic equipment. This versatile device has a wide range of applications, which makes it a popular choice in the industry.
