Through Hole Resistors have been an important part of electronic components for many years. One of the most popular components in the past has been the CW02C200R0JE70 (THR) resistor. In this article, we will discuss the application field and working principle of this resistor.

Application Field

The CW02C200R0JE70 THRs are mainly used in power supply circuits. These components limit the current in an electronic system and protect against voltage surges. This type of THR is particularly suitable for the operation of highly-sensitive components and high-voltage power supplies. In addition, the CW02C200R0JE70 THRs are also suitable for many other applications, such as overcurrent/overvoltage protection, pulse/signal conditioning, communications circuits, audio/video circuits and switching power supplies.

Working Principle

The CW02C200R0JE70 THRs are constructed using a metal oxide (ceramic or aluminum nickel chrome (AlNiCr) resistor element. The metal oxide element is composed of a high resistivity oxide-filled ceramic substrate. The oxide coating is then applied to this ceramic substrate to form the active resistor element. The whole construction is then placed inside an aluminum-plated housing that helps to prevent the component from shorting out.

The key to the functioning of a THR is the resistor element. The layer of metal oxide creates an electrical resistance due to the electrons\' inability to move freely through the oxide layer. This creates a voltage drop across the resistor element when current is applied, and this is known as resistance. The value of resistance is dependent on the size, shape, and materials used in the construction of the THR.

The CW02C200R0JE70 THRs are designed to be highly durable and stable due to the aluminum plating and oxide layer. This makes the component suitable for long-term use in circuits operating at high temperatures and voltages. The housing also protects against mechanical and environmental factors, such as vibration, shock, and corrosion. The THRs can also be used in high-frequency applications.

Conclusion

In summary, the CW02C200R0JE70 THR is a popular resistor for a wide range of applications. Its aluminum-plated housing and metal oxide resistor element make it highly durable and stable, and its robust construction allows for long-term use in circuits operating at high temperatures and voltages. Furthermore, its aluminum plating provides protection against mechanical and environmental factors, such as vibration, shock, and corrosion. In addition, the THR is suitable for use in high-frequency applications. The working principle of the THR is based on the electrical resistance created by the electrons\' inability to move freely through the oxide layer. Thanks to its many advantages, the CW02C200R0JE70 THR has become an important and reliable part of many electronic components.
