MFP25SBRE52-180K

Introduction

Through Hole Resistors are one of the most widely used components in the electronics and computer engineering industry. They provide a low-cost solution to resist high voltage or current flows, while also providing precision and reliable performance. The MFP25SBRE52-180K is a Through Hole Resistor and is suitable for high-current overvoltage three-phase applications. In this article, we will discuss the application field and working principle of the MFP25SBRE52-180K.

Application Field

The MFP25SBRE52-180K is designed for applications where high-current overvoltage three-phase is necessary. It is ideal for any situation where three-phase high-current overvoltage protection is required, such as in vacuum cleaners, washing machines, dishwashers, and other electrical appliances. The MFP25SBRE52-180K is capable of withstanding an overcurrent of up to 180kA for a duration of up to 5 minutes at a time. Its high surge-energy capacity and low heat dissipation make it well suited for continuous, high current overvoltage protection.

The MFP25SBRE52-180K is a multi-layer through-hole resistor. The structure uses a low-ohmic precision resistor between two layers of close-packed high-ohmic precision ceramic resistors. This ensures the high surge current is distributed evenly across the resistor, preventing excessive heat dissipation and ensuring a longer service life. The MFP25SBRE52-180K also features a silver-metallic layer on the outside of the resistor, which increases the temperature coefficient of the resistor while still providing high surge protection.

Working Principle

The working principle of the MFP25SBRE52-180K is based on the Joule’s Law, which states that the electrical energy dissipated in a conductor is equal to the square of the current multiplied by the resistance. In other words, when a surge of current flows through the MFP25SBRE52-180K, the energy that is dissipated is proportional to the current flowing through the resistor multiplied by the resistance. This dissipated energy is converted into thermal energy, which is then released as heat, thus reducing the amount of energy that reaches the connected components. This protective layer of thermal energy reduces the chance of electrical components failing due to overvoltage.

The MFP25SBRE52-180K also features a special metallic coating which increases its temperature coefficient. This ensures that the resistor will not exceed its rated temperature, even when subjected to extreme temperatures or high current surges. The higher temperature coefficient also makes the MFP25SBRE52-180K more suitable for applications requiring higher temperature stability such as heating systems and industrial machinery.

Conclusion

The MFP25SBRE52-180K is a Through Hole Resistor specifically designed for applications where high-current overvoltage three-phase protection is necessary. It is capable of withstanding an overcurrent of up to 180kA for a duration of up to 5 minutes at a time. Its multi-layer construction and special metallic coating allow it to dissipate high amounts of energy as thermal energy, thus reducing the chance of electrical components failing due to overvoltage. The MFP25SBRE52-180K is a reliable, cost-effective solution for applications requiring high surge protection and temperature stability.
