EMI/RFI Filters are essential components for the protection of any electronics system, and the FK2125T207AL-T model is no exception. A basic understanding of the application field and working principle of this filter is necessary in order to get the most out of it. In this article we’ll take a closer look at both.

In terms of application, the FK2125T207AL-T is primarily designed for EMI/RFI filtering and transient suppression in low voltage DC power supplies. It can also be used in automotive and any other applications requiring line frequency interference filtering. The filter features a high-efficiency “Y” type inductor and capacitor configuration, and is made up of a capacitor, resistor and inductor.

The working principle of the FK2125T207AL-T filter is quite simple. Incoming electromagnetic interference (EMI) and radio frequency interference (RFI) signals are absorbed by the high-efficiency “Y” type inductor and capacitor configuration. This attenuates the signals to a lower level, ensuring that the output of the power supply is not affected by the interference.

The FK2125T207AL-T filter also provides transient suppression, which is vital in any power supply system. This is achieved through the use of a capacitor in the filter, which provides a short-term energy storage buffer. This helps to absorb any sudden power surges and prevent them from reaching the output of the power supply.

To further enhance the performance of the FK2125T207AL-T filter, the resistor component is connected in parallel with the capacitor. This reduces the impedance of the filter, allowing for a higher current draw. In this way, the filter is able to handle high peak currents without impacting on the performance of the power supply.

In conclusion, the FK2125T207AL-T filter is an ideal choice for any application requiring EMI/RFI filtering and transient suppression. Its combination of a high-efficiency “Y” type inductor and capacitor configuration, as well as the parallel resistor, ensures that it is able to handle high peak currents without impacting the performance of the power supply. With its wide range of applications, the FK2125T207AL-T filter is an essential component in any DC power supply system.
