EMI/RFI Filters (LC, RC Networks) are an important component in telecommunications networks and networked systems. The performance and reliability of EMI/RFI Filters are critical in order to ensure that data transmission is secure and that the network is free from any detrimental interference. One of the most commonly used EMI/RFI Filters is the PEMI2QFN/HK,115. Understanding its application field and working principle will provide insight into how this EMI/RFI filter works and its intended uses.

The PEMI2QFN/HK,115 EMI/RFI Filter is a low-profile, eight-lead, surface-mount device. It features two leadless EMI/RFI filter cores and is designed for use with line card applications on PCBs. It has a maximum rated current of 1.5 A, and an effective insertion loss of up to 20 dB in the frequency range of 0.2 MHz to 3 GHz. This filter has a wide range of applications, from protection of sensitive systems and data from high-frequency EMI/RFI interference to providing feedback and detection/bias circuits in emergency and detection systems.

At its core, the PEMI2QFN/HK,115 is a low-impedance, low-capacitance device. It is composed of an inductor and capacitor array, which are connected in series. The inductor is connected to the power source and the capacitor is connected to the circuit. This combination of components forms the EMI/RFI filter. The filter components form an electrical resonance with the external circuit, which results in a resonance frequency and quality factor (Qc).

When there is high-frequency noise in the external circuit, the filter components will provide a low-impedance path for the noise to pass through. The filter core limits the amount of high-frequency noise that is allowed to pass through the filter, thus reducing the harmful effects of EMI/RFI interference. The insertion loss of the PEMI2QFN/HK,115 filter can be tuned to a specific frequency, allowing it to be used for more specific applications.

The PEMI2QFN/HK,115 EMI/RFI Filter offers reliable performance and low insertion loss in a small package. It is well-suited for use in a variety of applications, such as in-home telephone lines, co-location centers, telecommunications centers, and more. It provides a perfect balance of power, performance, and reliability that makes it one of the most useful components. With its ability to reduce EMI/RFI interference, it is clear that the PEMI2QFN/HK,115 offers a number of advantages over other EMI/RFI Filters.
