Slide potentiometers are electrical components that are typically used to measure and control electrical signals. The PTB0144-2010BPA103 is a commonly used type of slide potentiometer. It is a horizontal type slide potentiometer, which has an overall size of 6.3×8.6×5 mm. The resistance range is 10 kilo ohm to 50 kilo ohm and the rated power is 20mW. It has a single turn potentiometer with a linear taper and a shaft for short-time sliding.

The application field of the PTB0144-2010BPA103 mainly includes the volume control of audio systems, radio receivers, TV speakers, audio and video products, the selection switch of electronic sound effects, the adjustment of the frequency of radios or TVs and the setting of the length or speed of a time-related electrical device. The working principle of the slide potentiometer is relatively simple. The principle of the slide potentiometer is based on the resistive divider, which is composed of a nonlinear resistive element and a linear resistive element. When the slider moves, it rotates the resistive element to change the output voltage.

The output voltage VR can be expressed as: VR = Vs (Ra / R) to the dynamic range. Where Vs is the supply voltage, Ra is the nonlinear element and R is the linear element. As the slider moves, the voltage output across Ra changes and the resistance of the Ra element also changes, resulting in a varying voltage output across the entire linear range of the potentiometer.

In short, the PTB0144-2010BPA103 slide potentiometer is a common used linear potentiometer with a single turn and a linear taper, which is mainly used in audio and video products, radio receivers, TV speakers and electronic sound effects. Its working principle is based on the resistive divider. The output voltage can be adjusted by sliding the resistive element.
