Through Hole Resistors (THR) are essential electronic components used in applications where the necessary resitance needs to remain constant. They can be found in a variety of shapes, sizes and types, each designed to handle different circuits and applications. One of these potentiometers is the PF2472-0R18F1, a Through Hole Resistor designed to meet the stringent demands of modern circuitry.

This THR is a multi-turn potentiometer, designed with a rugged phenolic housing which allows it to stand up to a variety of environmental conditions including shock, vibration and humidity. It also features a precision conductive plastic element, allowing it to maintain a consistent resistance with a wide adjustment range. The PF2472-0R18F1 can be adjusted using a spanner wrench, locking it into the desired position.

This Through Hole Resistor is primarily used in sensitive applications, due to its long-term stability and reliable performance. It is suitable for a range of applications, including automotive, communication systems and power supplies. It can also be used for precision potting and trimming functions.

The PF2472-0R18F1 has a maximum power dissipation of 0.5 Watts and a rated voltage of 100V. It is available in single and double turn configurations, allowing it to be used in a variety of applications. It also has a built-in control dial which allows it to be easily adjusted.

The working principle of this multi-turn THR is based on the traditional potentiometer principle. It uses a fixed resistor together with a sliding contact, called the wiper, to set a specific resistance value. The resistance of the wiper is determined by its position along the resistor, and by turning the control dial, the user can adjust the resistance of the THR. As the resistance is adjusted, a voltage drop will occur across the fixed resistor, depending on the current flowing through it.

In conclusion, thePF2472-0R18F1 is a relatively simple THR that can be used in a wide range of sensitive applications. It has a rugged phenolic housing and a precision conductive plastic element which allow it to maintain a consistent resistance even in harsh environmental conditions. Additionally, it has a built-in control dial which allows it to be easily adjusted, making it a versatile and reliable component.
