Rotary potentiometers, rheostats, and PTR901-20ACK-A103s have many applications across an array of industries. The PTR901-20ACK-A103 is an example of a type of rotary potentiometer, a device used to measure electrical resistance. It is especially useful when measuring the resistance of AC or DC circuits.

A rotary potentiometer is an electrical component comprising of a resistive element, usually carbon, and a rotating contact arm. When the contact arm is turned, the resistance between the two points, or taps, on the potentiometer is changed. In most cases, the resistance has a linear relationship with the amount of rotation of the contact arm. This is why rotary potentiometers are often used in applications where an analogue signal is required for control, such as volume control of a stereo system.

The PTR901-20ACK-A103 is a rotary potentiometer with a range of 20kΩ to 100kΩ. It is a threeterminal device, meaning that there are three connecting pins, referred to as the wipers, or taps. The operating parameters of the device require a power supply of 1.0V to 5.0V and a maximum operating temperature range of -40℃ to 100℃. The rated power consumption of the device is 25mW when operated at a voltage of 2.7V. It has a maximum lifespan of 2000 cycles at 25℃.

The PTR901-20ACK-A103 is suitable for use in switching equipment, amplifiers, and other variety of circuit boards. It can also be used as an adjustable voltage divider, as it can divide voltages when the taps are set to different points on the resistance element. This makes it ideal for voltage controlled applications such as LED lighting and power supply management circuits.

The PTR901-20ACK-A103 operates on the same principles as other types of rotary potentiometers. It has a resistive element placed between two contact pins, and a third pin called the wiper which moves over the element when the shaft on the device is turned. As the wiper swings across the resistive element, the resistance between the two taps changes. As the resistance changes, so does the voltage, as the voltage is proportional to the resistance. This allows the device to be used as a voltage divider.

The PTR901-20ACK-A103 can also be used as a rheostat. A rheostat is a two terminal variable resistor, used to control the flow of current in a circuit. The device works by controlling the resistance in the circuit by changing the amount of current that flows through the resistor. Rheostats are commonly used to adjust the speed of motors, or to regulate the voltage of power supplies.

The PTR901-20ACK-A103 is a versatile and reliable device, which can be used in many applications. It is especially suited to applications which require a variable voltage source or a variable resistance. Its compact size, low power consumption, and small operating temperature range make it a popular choice for electronic manufacturers.
