## IntroductionEMI/RFI Filters (LC, RC Networks) are among the most versatile and effective components of electronic design, as they are used to protect sensitive circuits from interference caused by electromagnetic and radio frequency interference (EMI/RFI). PEMI8QFN/RP,132 is one such filter that is designed to provide superior protection from EMI/RFI. This article will provide an overview of the application field and working principle of the PEMI8QFN/RP,132. ## ApplicationsPEMI8QFN/RP,132 is a low-power, high-frequency filter ideal for a variety of applications. It is designed to attach directly to power distribution boards, controllers, and other sensitive equipment, and is often used in harsh or electrically noisy environments. Some applications include server racks, drive systems, industrial process control systems, and lab equipment. ## Working PrincipleThe PEMI8QFN/RP,132 is an inductor-capacitor (LC) filter made up of two inductors and two capacitors, connected in two parallel loops. Each loop contains one inductor and one capacitor, with the second inductor in the opposite phase. The circuit operates by forming an LC circuit, which has the ability to reduce the amount of interference caused by electromagnetic (EMI) or radiofrequency (RFI). The filter also has the advantage of low power consumption, meaning it does not require a large amount of electricity to operate.The way in which this filter works is by allowing only those frequencies that are in the desired range to pass through, while blocking or attenuating those that are out of the desired range. This is done by the inductor-capacitor circuit, which acts as a low-pass filter. The inductor-capacitor circuit is designed to allow the desired frequency to pass through, while blocking or attenuating any other frequency. This allows the desired frequency to pass through, while blocking any out-of-range frequencies.## ConclusionThe PEMI8QFN/RP,132 is a versatile, low-power EMI/RFI filter that is used in a variety of applications, from server racks to drive systems. It is a simple yet effective LC filter which operates by passing the desired frequency, while blocking any out-of-range frequencies. This ensures that sensitive circuits remain protected from EMI/RFI interference.
