EMI/RFI Filters (LC, RC Networks) are electrical filters designed for applications that require protection from Electromagnetic Interference (EMI) or Radio Frequency Interference (RFI). These filters are usually composed of two components: an inductor for attenuating low-frequency signals and a capacitor for attenuating high-frequency signals.

The PMR209MC6100M100R30 is an example of a network filter. It is a single-stage common-mode RF and EMI filter. It is designed to provide high-level filtering in low power applications similar to telecommunications, embedded network applications, and industrial control systems. The range of applications is quite broad and includes consumer electronics, automotive, and medical equipment.

The PMR209MC6100M100R30 filter has a maximum passband frequency of 10 Hz while its maximum stopband frequency is 1 kHz. It is composed of a 10.2uH inductor and a 100pF capacitor in parallel, and the whole filter is rated for 30V. The working principle of the PMR209MC6100M100R30 EMI/RFI filter is fairly straightforward. The inductor acts to reduce high frequency signal from entering or exiting the circuit, while the capacitor works to reduce low frequency signals. Together, they create an ac signal that is more than 95% attenuated in the stopband frequency while allowing ac signals with frequencies in the pass band to pass through unaltered. This ability of the filter to attenuate unwanted high and low frequencies while allowing desired signals to pass results in improved performance.

In addition to its attenuation ability, the PMR209MC6100M100R30 filter also offers integrated EMI shielding. This shielding greatly reduces the RF leakage of the filter, making it suitable for radio frequency applications. Additionally, the shielding also serves to protect the filter from external interference. This enables the filter to maintain its performance even in environments with high levels of EMI.

In summary, the PMR209MC6100M100R30 filter is an ideal solution for applications requiring high-level filtering in low power applications such as telecommunications, embedded network applications, and industrial control systems. Its ability to attenuate high and low frequencies while allowing desired signals to pass makes it a cost-effective and reliable choice.
