EMI/RFI Filters (LC, RC Networks)

Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI) are two of the most common problems encountered in the field of electronic engineering. Utility lines, wireless networks, and electronic devices often send out noise, and these signals can cause interference with other electronic equipment. The solution to this problem lies in the use of filters to reject the unwanted signals from entering or leaving certain devices. EMI/RFI Filters are the most widely used type of filters, and they are categorized into two categories- LC (inductor-capacitor) and RC (resistor-capacitor) networks.

FN7660-200-M10 EMI/RFI Filters

FN7660-200-M10 is an LC filter from FNL Filters. This filter offers high rejection of both EMI/RFI signals as well as providing excellent impedance performance. It is constructed from a combination of inductors and capacitors and is designed to meet EN 60950 requirements. This filter is highly reliable, and provides excellent attenuation of EMI signal up to 200 MHz. The FN7660-200-M10 has two separate networks, operating at 50/60 Hz, and provides high common mode rejection ratio (CMRR).

Application Field and Working Principle

The FN7660-200-M10 can be used in a wide variety of applications, such as data centers, industrial networks, automotive systems, smartphones, and medical devices. It is typically deployed between the power or data line and the equipment to be protected. The filter also includes an integrated magnetic core which acts as an EMF absorber.

The FN7660-200-M10 operates on the principle of impedance matching. The inductors are responsible for passing the alternating current, while the capacitors are responsible for blocking the high frequency noise from entering the equipment. The inductors also tune the frequency response of the filter so that only signals within the desired frequency band will be passed through.

The FN7660-200-M10’s two separate circuits act in concert to provide noise suppression in both common mode and differential mode. The common mode circuit will block any interference coming into the system on one line, while the differential mode circuit will block any interference passing between the two lines. This combined action makes the FN7660-200-M10 highly effective at blocking noise.

Conclusion

The FN7660-200-M10 filter is an excellent choice for noise suppression in electronic systems. With its combination of inductors and capacitors, it provides excellent EMI/RFI noise suppression up to 200 MHz. It also offers very high CMRR and a reliable design that meets EN 60950 requirements. The FN7660-200-M10 is suitable for use in a variety of applications such as data centers, industrial networks, automotive systems, smartphones, and medical devices.
