Power Line Filter Modules

Power line filters, also known as EMC filters, are devices designed for the purpose of reducing electromagnetic interference (EMI) caused by electrical and electronic equipment. The B84111A0000B120 filter module in particular, is widely used in electrical and electronic systems to suppress source-generated EMI and to protect nearby electronic equipment from conducted and radiated noise.

Design

The B84111A0000B120 filter module is designed to have an enclosure affairing the metal components which give an approximate rating of IP 20. The metal components, such as casing, brackets and cable shields are designed to provide necessary grounding and shieding effectiveness. The major physical components of the filter module don’t need any explanation as they are all integrated together, while some minor components like fixing screws and support members are also seen in the filter module.

Application Field

The filter module is primarily used in power supplies, AC adapters, and DC/DC converters or any other applications that require the use of wide bandwidth line-powered circuits. Moreover, the B84111A0000B120 filter module can also be used for protection in industrial, car and aerospace applications.

Working Principle

The working principle of the B84111A0000B120 filter module is quite simple. It works by placing a carefully selected and tuned inductive element in series with a power supply line in order to reduce the amplitude (magnitude) of the conducted EMI versus frequency. The strength of the EMI reduction is dependent on the peak value of the inductive element. The filter module also contains capacitors that only allow frequencies with a lower impedance to pass. This allows the filter to reject certain frequencies while allowing the desired frequency to pass through.

Other Features

The B84111A0000B120 filter module also offers several additional features, such as:- Low impedance and immunity to harmonic distortion- Excellent shielding properties due to high impedance and low current leakage- Excellent noise attenuation performance- Effective impedance matching- Good line/load regulation- Excellent filtering of noise over wide frequency range- Low differential mode currents

Conclusion

The B84111A0000B120 filter module is an effective device for reducing electromagnetic interference (EMI) and for providing protection against conducted and radiated noise. It is capable of providing low impedance and immunity to harmonic distortion, while also offering excellent shielding and noise attenuation performance. This makes it perfect for use in power supplies, AC adapters, and DC/DC converters, as well as protection in industrial, car and aerospace applications.
