EMI/RFI Filters, or LC and RC circuits, are components used to reduce conductive and radiative emissions as well as to protect electronic equipment from external electromagnetic interference (EMI). The PEMI4QFN/RM,132 filter is a four-pin QFN/RM filter specifically designed to offer increased performance in reducing conducted and radiated emissions in the frequency range of 150K Hz to 1GHZ.

This filter provides superior performance by using a high polarization ceramic chip capacitor in a bulk metal plate. This ensures excellent impedance matching to the device being filtered by allowing for a limited resistance/inductance value, thus providing a low insertion loss and high attenutation. The ceramic chip capacitors also provide a better mechanical stability and environmental protection over other filter technologies. Additionally, the high polarization materials allow for a low EMI factor and a much lower thermal sensitivity compared to other technologies.

The PEMI4QFN/RM,132 filter utilizes a shielded high-frequency common mode filter topology, and two surface mount resistors in order to provide a very high attenuation across the complete frequency range. This will significantly reduce both conducted and radiated emissions. The filter also features a fast recovery snap ring design which helps to reduce ringing and EMI while providing excellent stability. Moreover, the filter can also effectively reduce electrical noise at the source to preserve the accuracy of sensitive electronic equipment.

Applications of this filter include automotive applications, medical equipment, power supplies, and telecommunications equipment. It can also be used in both in-vehicle and industrial EMC (electromagnetic compatibility) applications. The PEMI4QFN/RM,132 filter provides protection from EMI harm across a wide frequency range, from 150K Hz to 1GHz, and is optimized for use in the more challenging electromagnetic environment commonly found in automotive, industrial, and medical applications.

In conclusion, the PEMI4QFN/RM,132 filter is an engineered EMI/RFI filter that is specifically designed to offer superior performance in reducing conducted and radiated emissions in the frequency range of 150K Hz to 1GHZ. It utilizes a shielded high-frequency common mode filter topology and two surface mount resistors to achieve a high attenuation rate, superior temperature stability, low EMI factor, and is suitable for use in industrial, medical, and automotive applications. The PEMI4QFN/RM,132 filter is an effective solution for controlling electromagnetic interference and protecting sensitive electronic equipment.
