Rotary Potentiometers, Rheostats

The EWV-YEMU04B14 is a rotary potentiometer and rheostat. It is a type of variable resistor that can be adjusted with a rotary knob. It is commonly used in electronic circuits to control the voltage, resistance, or other parameters for feedback loops and adjustable gain amplifiers.

The working principle of the EWV-YEMU04B14 is relatively simple and can be described as follows. When the rotary knob is turned, a wiper comes in contact with a resistive track which is printed on the body of the device. As the knob is turned, the wiper moves across the track, increasing or decreasing the resistance value. This movement is then translated into an electrical signal which can be used to adjust the parameters of the electric circuit.

The EWV-YEMU04B14 can be used in many different applications. They can be used as a voltage regulator for operating power supplies. They can also be used to control motor speeds, adjustable gain amplifiers, and adjustable bias current sources. They are also often used in audio applications such as guitar amplifiers and volume controls.

The EWV-YEMU04B14 is a reliable and robust device that can be used in many different applications. It is relatively easy to install and use, and it can be used to adjust different parameters in electronic circuits. Its accuracy and repeatability make it an ideal choice for applications that require precise control. The EWV-YEMU04B14 is a versatile and reliable device that can be used to adjust different parameters in a wide variety of applications.
