EMI/RFI filters, often called LC, RC networks, are electrical filters that are used to reduce the effects of electromagnetic interference (EMI) or radio frequency interference (RFI) on electronic systems. The 4420P-T06-101/201 is an EMI/RFI filter that is designed for high frequency power line filtering. This article will explore the application field and working principle of the 4420P-T06-101/201 filter.

The 4420P-T06-101/201 is an ideal filter for high frequency power line filtering. It is suitable for the elimination of conducted noise generated by switching power supplies, aircraft, computers, telecom devices, medical equipment, and other electronic devices. The filter works by attenuating the conducted emissions falling within the frequency range from 0.15 MHz to 50 MHz. The filter is designed with two channels, each of which can provide up to 30 dB of insertion loss over this frequency range. It also provides up to 50 dB of common mode filtering.

The 4420P-T06-101/201 filter is constructed from high quality ferrite cores, which are surrounded by a conducting path. This conducting path forms the inductance and capacitance values necessary for proper filtering. The filter is then connected to the power source and the device being filtered. The inductors and capacitors in the filter work together to attenuate the EMI and RFI signals. The inductors reject high frequencies while the capacitors reject low frequencies. The combination of these two components forms the necessary transfer function that reduces the amount of noise entering the device being filtered.

In order to properly install the 4420P-T06-101/201 filter, it is important to ensure that the connections are secure. The filter must be connected in-line with the power source and the device being filtered. It is also important to ensure that there is a good ground connection between all parts of the system. This is necessary for proper operation of the filter.

In summary, the 4420P-T06-101/201 is an EMI/RFI filter designed for high frequency power line filtering. The filter works by attenuating the conducted emissions falling within the 0.15 MHz to 50 MHz frequency range. It is constructed from high quality ferrite cores and utilizes inductors and capacitors to provide up to 30 dB of insertion loss and up to 50 dB of common mode filtering. In order for the filter to work properly, it must be connected in-line with the power source and the device being filtered and have a good ground connection established between all parts of the system.
