This filter contains two common mode chokes (also known as common mode inductors). When common mode interference occurs, due to the same direction of flux in both coils, the total inductance increases rapidly after coupling Mode signal showing a great sense of resistance, so that it is not easy to pass. Its two coils are wound around the low loss, high permeability ferrite ring, when there is current through the two coils on the magnetic field will strengthen each other, the filter performance can also improve the low frequency attenuation characteristic.
Power supply "zero line" and "FireWire" to add up to 7pcs capacitor to absorb the noise filter out the module interference, so that the entire filter to achieve a very good effect.
The devices used in this filter are all safety devices, please rest assured that use.
The entire filter is very small, the installation of small footprint, four corners are designed to install holes, easy to install.
The specific installation of friends should be clear, here only warm tips:
