Through Hole Resistors are an important component in electrical systems. PF2205-0R24F1 is a type of through hole resistor that is widely used in a variety of applications.

Design

PF2205-0R24F1 is a usually preferred resistor in a through hole format and is designed to withstand the effects of a variety of aggressive environment conditions such as temperature, humidity, vibration, and shock. The design consists of a polyamide-based film encapsulated between two sheets of conductive nickel-plated copper foil and being marked with a printed code and the resistance value. The heat generated by the resistor is dissipated by the copper-plated housing and a sponge-type thermal insulator.

Applications

PF2205-0R24F1 is mainly used in power and high voltage applications where reliability is key. Typical applications include AC/DC power regulation, motor control, automotive electronics, robotics, aerospace, and agricultural equipment. Its operation voltage range is up to 1.4kV and power dissipation of up to 0.5 W. These resistors are also commonly used in a variety of amplifiers, voltage converters, and load testing.

Working Principle

The working principle is based on the conversion of electrical energy into heat, thereby providing variable resistive value to the component. The resistive value can be adjusted by adjusting either the size of the resistor film, or the thickness of the metal film. The resistor film itself consists of indium oxide that is sandwiched between two sheets of conductive material. The resistance of this film is inversely proportional to the film thickness and as such, it is possible to adjust the resistance of the resistor by altering the thickness of the film.

The PF2205-0R24F1 also features an air gap in order to prevent damage due to overheating. This air gap helps to dissipate excess heat, thus avoiding the risk of thermal runaway.

Conclusion

PF2205-0R24F1 Through Hole Resistors are highly reliable, capable of withstanding extreme environments while offering good performance. With the ability to adjust the resistive value by altering the thickness of the film, they can be customized for a wide range of applications. Furthermore, they are highly durable and reliable as well as cost-effective.
