EMI/RFIFilters (LC, RC Networks) have been widely used in various application fields nowadays. MEM2012F25R0T001 is a relatively popular EMI/RFI Filter, and this article will explain its working principle and application field.

The MEM2012F25R0T001 is a bidirectional EMI filter which is composed with capacitors and a coil. It has two screw terminals which enable to easily connect with other circuits. The internal construction of the filter contains a coil with an inductance of 25mH in series and two capacitors of 470uF in parallel. It also has two parts of an electric shield, one is connected to ground and the other between the series and parallel. This filter has a wide frequency range from 150KHZ to 500MHZ, and it can filter out the noise which is generated from the electro-magnetic interference (EMI) and radio frequency interference (RFI).

The working principle of MEM2012F25R0T001 is relatively simple. The coil will act as an inductor to block the high frequency EMI and RFI signals. The capacitors and electric shield will convert the high frequency signals into low frequency by the resonance characteristics. Therefore, the filter could block the EMI and RFI, and provide high quality signal transmission.

MEM2012F25R0T001 has many application fields. Firstly, it is widely used in military devices such as weapon system and military airplane. On one hand, it is able to filter out EMI and RFI from the weapon system so that the system can accurately detect and respond to the situation. On the other hand, it can also protect the military aircraft from EMI and RFI so that the airplane can fly safely and accurately. Secondly, it is also widely used in medical devices, for example, the CT scanner and ultrasound imaging systems. The filter can filter out the high frequency interference and guarantee an accurate imaging results. Last but not least, MEM2012F25R0T001 is widely used in electronic gadgets, such as smartphones and tablets. The filter is able to outline the strong interference signals so that the devices can work normally and transmits accurate signals.

The application and working principle of MEM2012F25R0T001 have been illustrated. As a bidirectional EMI/RFI Filter with a wide frequency range, MEM2012F25R0T001 is an ideal product for military, medical together with the electronic gadgets. It can significantly reduce the interference due to EMI and RFI, and provide high quality signal transmission.
