B84742A0055R190

Power line filter modules, such as B84742A0055R190, are essential components for protecting electrical equipment against interference. This filter module can be found in a wide range of applications, including automotive, medical and industrial systems. It can provide efficient noise suppression on three levels: differential-mode, common-mode and high frequency noise.

Applications

B84742A0055R190 is suitable for both residential and commercial applications. It is designed for use in applications such as HVAC/R, home appliances, vending machines, office machines, medical instruments and other electrical equipment, offering a reliable and effective solution for noise interference suppression. Its electrical parameters also comply with standard European EMC requirements, such as EN55011 and EN55022. Additionally, this filter module can decrease undesired emissions, which can be a major contributor to product failure due to interference.

Features

This power line filter module features an integrated design, ensuring better EMI and EMC filtering performance than a conventional choke-based filter. As it uses a combination of capacitors and common-mode and differential-mode chokes, it has excellent attenuation at different frequencies. In addition, the B84742A0055R190 has a temperature resistant UL94VO flammability rating, making it suitable for use in a wide temperature range. It also has a high surge capability and a long life expectancy due to its solid-state construction.

Working Principle

The power line filter module works by suppressing noise at different frequencies in order to reduce the electrical interference that can be caused by the currents. In essence, it provides an additional level of protection against noise interference and electromagnetic interference, thus keeping the electrical system functioning properly. The B84742A0055R190 is composed of a capacitor, two common-mode chokes and two differential-mode chokes. The capacitor absorbs and blocks high frequency noise, whereas the common-mode and differential-mode chokes reduce the noise at lower frequencies.

Conclusion

The B84742A0055R190 power line filter module is an ideal solution for protecting various electrical systems and electronic equipment from noise interference in residential, commercial and industrial applications. The integrated design of the filter module offers excellent EMI and EMC filtering performance. Furthermore, it features a temperature resistant UL94VO flammability rating and a long life expectancy due to its robust solid-state construction.
