The EMI/RFI Filters (LC, RC Networks) are a type of electronic device used to protect a connected device from electromagnetic interference (EMI) and radio frequency interference (RFI). The PEMI8QFN/HG,132 is a state-of-the-art EMI/RFI Filter which can be used in a broad range of applications. This article will provide an overview of the applications of the PEMI8QFN/HG,132 and its working principle.

Applications: The PEMI8QFN/HG,132 is well-suited for applications that require high reliability and minimal insertion loss. It is a popular choice for a variety of industrial, commercial, and consumer applications, such as: power supplies, telecom equipment, automotive electronics, and medical devices. The filter is also suitable in high frequency circuits, as it can operate up to a frequency of 8Ghz. Its low frequency range, up to 1GHz, makes it a great choice for general-purpose applications and telecommunication systems.

Working Principle: The PEMI8QFN/HG,132 utilizes high-performance multi-layer ferrite/ceramic micro-capacitors arranged in multiple stages. The inductor blocks along with deposited inter-stage capacitor layers form an LC filter circuit that attenuates noise between the input and output of the filter. The capacitors and inductors filter the high frequency noise from the signal path, while the RC network improves the filter’s high frequency isolation. This ensures that the PEMI8QFN/HG,132 has the ability to significantly reduce common mode as well as differential mode noise. The filter also features an EMC shielding metal case which helps further address EMI/RFI problems.

Overall, the PEMI8QFN/HG,132 is a reliable and highly efficient EMI/RFI filter which is suitable for a range of applications. Its active micro-capacitor structure enables it to reduce high frequency noise and significantly improve isolation levels, making it an ideal choice for applications in power supplies, telecom equipment, automotive electronics, and medical devices. Its low frequency range and high frequency performance up to 8GHz make it suitable for general-purpose applications.
