Power Line Filter Modules 55BCF6R Application Field and Working Principle

The 55BCF6R line filter modules are part of a wide range of power line filter devices from Murata Power Solutions that helps meet stringent global safety and EMI standards for various electrical equipment and components. This type of filter reduces both common and differential mode conducted electromagnetic interference (EMI), helping to ensure reliable operation of industrial and medical applications where high levels of noise interference could cause critical operational failure.

Application Field

The 55BCF6R line filter module is well-equipped to enhance the function of switch mode power supplies and other electronic devices in the industrial, medical and telecommunication industries. The filter offers attenuation from 15kHz to 30MHz and provides valuable attenuation by effectively blocking EMI. The 55BCF6R module is available in a 6-pin single-in-line (SIP) package and is capable of operating at currents of up to 100A.

Working Principle

The 55BCF6R line filter modules use state-of-the-art film capacitors and ferrite materials in its construction. The ferrite filter core is mounted on a printed delicate board with through-hole mounting, while the capacitors are connected in a pi-configuration which offers high-frequency attenuation and low noise. Essentially, the capacitors block the excessive noise and single-line EMI from other generators, while the ferrite allows for high-frequency currents to pass through without interference.

To help attain a soft switching performance, the filter module also has a voltage drop of 1V at 25A. Additionally, the device is RoHS compliant and UL certified for safety and quality.

Conclusion

The 55BCF6R is a versatile line filter module with low-pass characteristics. It provides maximum attenuation up to 30MHz for conducted interference and is specially designed to reduce risk of interference in switch-mode power supplies and other electronic applications. Overall, it is an excellent choice for customers seeking effective protection against EMI in industrial, medical and telecommunications fields.
