P090L-02F20BR50K

The P090L-02F20BR50K is a rotary potentiometer made from cermet materials. It has a 50K ohm resistance value and a power rating of 0.5W. It is designed to be used in audio and electrical devices that need to control variable voltage and current flows. Examples of such applications include remote control cars, multimedia players, digital camera, scanner, and other similar appliances.

The P090L-02F20BR50K is a three terminal device. The two outer terminals are connected to a resistor that forms a voltage divider circuit. When the wiper is moved, the resistance between the two outer terminals changes, producing an output voltage that is proportional to the position of the wiper.

The P090L-02F20BR50K works the same way as a rheostat. However, rheostats are typically made with thicker resistors and variable resistances up to several hundred Ohms. Thus, while rheostats can be used to regulate higher currents, potentiometers are better suited for regulating low current flows.

Installing the P090L-02F20BR50K into a circuit is a relatively straightforward process. First, the outer two terminals of the potentiometer are connected to the voltage source and then the wiper is connected to the desired location in the circuit. By adjusting the position of the wiper, the user can control the voltage output of the circuit.

In summary, the P090L-02F20BR50K is a rotary potentiometer that is designed to regulate variable voltage and current flows. It works by forming a voltage divider circuit with two outer terminals and a wiper that can be adjusted to change the residual resistance between the two terminals. It can be used for controlling remote control cars, multimedia players, digital camera, scanner, and other similar appliances.
