EMI/RFI filters are typically used in electronic equipment in order to protect sensitive components from high frequency interference. PEMI2QFN/HG,115 is one such filter, which is designed to reduce the electromagnetic influences on high-speed data lines. This application field and the working principle of the EMI/RFI filter is discussed in this article.

The PEMI2QFN/HG,115 is an EMI/RFI filter designed for high-speed data line applications, which provide a variety of solutions for the shielding of external noise on sensitive systems. The filter features a unique construction that ensures maximum conductivity and shielding effectiveness across a wide frequency range. This filter provides high-performance, high-efficiency anti-EMI noise cancellation, and is commonly used in high-speed data lines such as Ethernet, USB, and DisplayPort.

The PEMI2QFN/HG,115 is a high-frequency filter designed for applications with a wide frequency range, from 150 kHz to 30 GHz. It has a maximum insertion loss of 0.5 dB and a maximum return loss of 30 dB. The filter is also capable of providing an extremely low thermal resistance of 0.7 Ω.

The performance of the PEMI2QFN/HG,115 EMI/RFI filter is based on the use of a unique transmission line design, which is constructed by sandwiching two layers of copper together with a high-temperature dielectric material. This design is optimized to reduce attenuation across the frequency range and provide a high-efficiency shield against external interference.

In addition, the filter is designed with an air gap layer between the power and signal layers, which effectively reduces common mode noise generated from the power supply. The air gap also enhances the filter\'s characteristics at ultra-high frequencies, making it an ideal solution for the reduction of EMI on high-speed data lines.

The PEMI2QFN/HG,115 EMI/RFI filter offers excellent performance and shielding effectiveness, making it a popular choice for applications with high-speed data line shielding requirements. The filter offers a wide frequency range, low insertion loss, and low thermal resistance, making it a highly-efficient solution for shielding external noise interference. Therefore, this filter is ideal for a variety of applications, such as USB, Ethernet, and DisplayPort.
