PEMI6QFN/CM,132

EMI/RFI Filters (LC, RC Networks) are used to reduce the noise in power and signal lines, and protecting sensitive equipment from interference. The PEMI6QFN/CM,132 is one such filter, which has specific application fields and a designated working principle.

This filter is mainly used for automotive systems, where reliability is particularly critical.It features a unique, all-in-one design thatintegrates 6 inductors on the same single component, which not only reduces the system size but also improves the noise suppression performance. Thanks to its compact size，it can be used in tight spaces, while still providing effective protection.

In terms of its working principle, it is able to suppress conducted EMI noise by shunting it to ground, with inductive and capacitive components. It also eliminates differential mode noise by using inductor chokes. All these work together to provide effective noise reduction in both the common and differential mode. The PEMI6QFN/CM,132 is particularly effective at reducing power line overshoot, undershoot and ringing.

This type of filter is best suited for DC-DC converters, such as point-of-load (POL) regulators, as they require the highest level of noise suppression. It is also suitable for automotive systems where reliability and robustness are particularly important, as well as in electronics where small size is a priority. Furthermore, because of its low profile package, it can fit into tight spaces and provide effective protection and noise suppression without taking up too much space.

In summary, the PEMI6QFN/CM,132 is an all-in-one EMI/RFI filter that provides effective noise reduction and protection. It is mainly used for automotive systems and DC-DC converters, and is suitable for tight spaces due to its low profile package. Its working principle is based on shunting the conducted EMI noise to ground with inductive and capacitive components, and eliminating the differential mode noise with inductor chokes.
