EMI/RFI filters are electronic devices used to reduce the electromagnetic interference generated in a system. They are typically used when interference levels become too high and need to be attenuated. One of the more common EMI/RFI filters used in today’s systems is the PEMI4QFN/WP,132. This part is used in a wide variety of applications and is designed to provide protection from EMI and RFI. In this article, we will discuss the application field and working principle of the PEMI4QFN/WP,132 EMI/RFI filter.

The PEMI4QFN/WP,132 EMI/RFI filter is primarily used in communications systems for protection against radio and electric signals. It is designed to attenuate both EMI and RFI signals from entering or leaving the system. The part is small and quite versatile as it can be used in both linear and switched circuits, providing excellent shielding performance up to 5GHz. It is also capable of handling a wide range of power levels, from ultra low power to high power up to 20 Watts. In addition to its versatility, the PEMI4QFN/WP,132 filter is also highly reliable and offers a high degree of immunity against EMI.

The working principle of the PEMI4QFN/WP,132 filter is based on an LC, RC network. It consists of two balanced and symmetric filter networks. The first network, known as the high-pass filter, is designed to block low frequency signals. The second network, called a low-pass filter, is designed to block higher frequency signals. Each network is tuned to a specific frequency range and the crossover point between the networks is adjustable so it can be tuned to the desired operating frequency. The combination of the two networks provides excellent performance in rejecting both EMI and RFI signals.

The PEMI4QFN/WP,132 is ideal for use in a wide variety of applications. Some of the more popular applications are in audio systems, cordless phones, wireless communication systems, and industrial equipment. It is also widely used in medical and military applications. The PEMI4QFN/WP,132 offers excellent performance, excellent shielding, and reliability, making it an ideal EMI/RFI filter for a wide range of applications.

In conclusion, the PEMI4QFN/WP,132 EMI/RFI filter is a highly versatile and reliable filter designed to protect against electromagnetic interference. It is based on an LC, RC network and is capable of handling a wide range of power levels. The filter is suitable for use in a wide range of applications, from audio systems to military applications. The PEMI4QFN/WP,132 offers excellent shielding and reliability which makes it an excellent choice for EMI/RFI protection.
