EMI/RFI Filters (LC, RC Networks)

The FN7612-250-M12 is one of the latest filter products in the market that is used in applications of Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI) filtering. A application field of this filter can include automotive, medical, industrial, consumer electronics, and military applications where high performance filtering is required.

The FN7612-250-M12 employs a 3-phase multi-stage inductor/capacitor/resistor network that is designed to suppress radiated EMI and/or RFI signals in power conversion applications. This filter is composed of two common filter elements: an inductor (LC) and a resistor-capacitor (RC) filter. The filter is designed so that the two different elements work together to reduce the amount of interference signal that reaches the end user.

The filter LC element is essentially an inductor which effectively blocks high-frequency signals. This action results in a low-pass filter that attenuates signals above a certain frequency known as the cutoff frequency due to the inductance afforded by the inductor. The filter RC element, which consists of a resistor and a capacitor, is responsible for blocking or attenuating signals with frequency components lower than a certain cutoff frequency as determined by the ratios of the component values.

When the two elements are combined, the filter has a much broader range and can attenuate frequencies lower and higher than those that are blocked by each of the elements individually. The filter is designed to have a high attenuation of both high- and low-frequency components, which will reduce the amount of interference signals that reach the end user and thereby improve overall system performance.

The FN7612-250-M12 filter also includes additional features such as electromagnetic compliance ratings, a self-shielded construction, and a wide operating temperature range depending on application requirements. This filter is suitable for any type of application where high performance EMI/RFI noise elimination is desired. It is designed to effectively reduce the amount of electromagnetic noise that passes through the system and provide clean and reliable power for the system.

In summary, the FN7612-250-M12 filter is designed to effectively attenuate electromagnetic and radio frequency interference to improve the overall performance of a system. The filter consists of both LC and RC elements that work together to attenuate high- and low-frequency noises, reducing the amount of interference signals that reach the end user. This filter can be used for a variety of applications and offers features such as electromagnetic compliance ratings, self-shielding, and a wide operating temperature range.
