EMI/RFI Filters (LC, RC Networks) are electronic devices used in a variety of applications to control the flow of electrical current. The PEMI2QFN/LT is a type of EMI/RFI filter specifically designed to protect electronic circuits from electromagnetic interference (EMI) and radio frequency interference (RFI). This filter is mainly used in automotive, consumer, and industrial applications to reduce the effect of EMI or RFI on sensitive components.The PEMI2QFN/LT consists of two components: an inductor and a capacitor. The inductor is made up of a coil of wire and serves to impede the flow of alternating current (AC) in the circuit. It works by storing energy in its magnetic field whenever current is flowing through it. This energy is then discharged as a voltage spike or an undesired signal when the current is cut.The capacitor is made up of two plates: one conducting and one insulating. It works by blocking the flow of direct current (DC) in the circuit. It also serves to reduce the amount of interference from external RF signals. The capacitor is connected in parallel with the inductor to form an LC network, which effectively filters out undesired signals.The PEMI2QFN/LT filter also includes a resistor to absorb any remaining high-frequency energy. This resistor is connected in series with the inductor and capacitor, and serves to limit the frequency of allowed signals. It works by attenuating signals with frequencies above its cutoff frequency, reducing the overall level of interference in the circuit.This filter is designed to meet specific requirements in terms of size, weight, and electrical performance. It is able to handle high-power applications without causing overheating or damage to the connected device. Additionally, the PEMI2QFN/LT is RoHS (Restriction of Hazardous Substances) compliant and is suitable for use in both residential and commercial applications.In summary, the PEMI2QFN/LT is an effective EMI/RFI filter for automotive, consumer, and industrial applications that help protect against interference from external signals. It is a combination of an inductor, capacitor, and resistor that creates an LC network to absorb and reduce undesired signals. The PEMI2QFN/LT is designed for maximum performance and reliability and is suitable for a wide range of applications.
