Trimmer potentiometers are uniaxially adjustable mechanical components that act as a three-terminal resistor. They can be used to adjust the resistance of a circuit while the circuit is powered. This makes them useful in applications where a resistance value must be precisely set. The 23AR100LFTR is a common trimmer potentiometer and it has a variety of applications and a unique working principle.

Application field

The 23AR100LFTR is a valuable tool for controlling variable voltage or current in a variety of circuits. It is a common component found in audio-visual equipment, such as TVs and radios. It can also be used to adjust the frequency of oscillators, such as a crystal oscillator. It can be used to set the brightness of a display or backlighting in computers and some smartphones.

The 23AR100LFTR is also commonly used in motor control circuits. It is used to adjust the speed of a motor by controlling the amount of current flowing through the motor. It is also used in pulse-width modulation circuits, which allow the motor to run at variable speeds. Many robot systems also use trimmer potentiometers to adjust the direction and speed of a motor.

Finally, the 23AR100LFTR is widely used in power electronics, such as transformers and switch-mode power supplies. In switch-mode power supplies, it is used to adjust the oscillator frequency, while in transformers it is used to adjust the voltage and current of the circuit.

Working Principle

The working principle of the 23AR100LFTR is based on the fact that it is a three-terminal resistor. The two outer terminals are the high and low ends of the variable resistor, while the center terminal is the Control Terminal. The Control Terminal is connected to one end of a spring-loaded slider, which is driven by a fine adjustment screw. As the adjustment screw is turned, the position of the slider changes, which changes the resistance between the two outer terminals.

The 23AR100LFTR has a wide adjustment range, from 0.1 ohms to 100 ohms. It also has an operating temperature range of -40°C to 85°C, which makes it suitable for many applications. The 23AR100LFTR is also relatively inexpensive, making it a popular choice for many electronics engineers.

Conclusion

The 23AR100LFTR is a popular trimmer potentiometer used in a variety of applications. It is a three-terminal resistor, with a wide adjustment range and operating temperature range. It can be used to adjust the voltage or current in a circuit, as well as to adjust the speed of a motor or the frequency of an oscillator. It is a versatile and inexpensive component that is used in many electrical and electronics applications.
