CFR25SJR-52-2K2 Through Hole Resistors Application Field and Working Principle

Through hole resistors are widely used in electronic circuit boards. They act as a source of current or voltage in electronic circuits, providing a wide variety of resistive values. The CFR25SJR-52-2K2 series of through hole resistors has become an increasingly popular choice due to its cost and reliability. In this article, we’ll explore the application field and working principle of the CFR25SJR-52-2K2 series of through hole resistors.

Application Fields

The CFR25SJR-52-2K2 series of through hole resistors is an ideal choice for applications where precision and reliability are critical. These resistors are particularly well-suited for use in audio, medical, automotive, telecommunication, and consumer-electronic applications.

Construction Type

The CFR25SJR-52-2K2 series of through hole resistors is composed of a series of epoxyl-sealed resistors with metallized film. These resistors are hermetically sealed to prevent any dust or moisture from entering the resistor. The resistor is usually surrounded by an insulating coating to prevent any exposed metal parts. This serves to protect the resistor from any environmental elements, such as moisture, dust, and corrosion.

Features

The CFR25SJR-52-2K2 series of through hole resistors offers many advantages, such as:

• Excellent resistance to vibration and shock.
• Excellent temperature stability.
• Excellent high-temperature performance.
• High insulation resistance.
• Excellent stability of resistance values.
• High reliability.

In addition, the CFR25SJR-52-2K2 series of through hole resistors offer an excellent range of resistive values, ranging from 1KΩ to 10KΩ.

Working Principle

A through hole resistor works by providing an electrical resistance between two points in a circuit. When power is applied across the resistor, electrical current flows across it, creating an electrical field that creates a resistance to the flow of current. This resistance is based on the value of the resistor – the higher the value of the resistor, the greater the resistance it provides. The resistance of a through hole resistor is calculated by multiplying its resistance value by its length. The resistive value of the CFR25SJR-52-2K2 series of through hole resistor is determined by the amount of epoxyl-sealed metallized film used in its manufacture.

Conclusion

The CFR25SJR-52-2K2 series of through hole resistors is an excellent choice for applications that demand precision and reliability. Its attractive combination of features, including its excellent resistance to vibration, temperature stability, and environmental protection, makes it an attractive choice for a wide range of applications. In addition, its wide range of resistive values makes it suitable for applications requiting varying levels of resistance.
