PEMI4QFN/CM,132

EMI/RFI filters are devices used to suppress electromagnetic interference or radio frequency interference. They can be of two types - LC networks or RC networks. PEMI4QFN/CM,132 is one such filter, which belongs to the RC networks family. This application field section outlines the use of this filter and the following section will discuss its working principle.

The PEMI4QFN/CM,132 is primarily used for switching power supplies, VCRs, consumer electronics, LED lighting, solar applications and automotive electronics. It is able to handle up to 4A current and is a temperature-stable device with low stray inductance, hence providing good common-mode performance. This filter also has a high attenuation of noise from switching power supplies, VCRs and automotive electronics due to its high frequency characteristics.

The working principle of the PEMI4QFN/CM,132 is quite simple. This filter uses capacitors, which are designed to control the current flow. This works as it stores charge and filters out the noise from a power source. When a current flows through the capacitor, it stores some of it, while some is allowed to pass through. This reduces the amount of noise being generated and transmitted from electronic components, such as power supplies, VCRs and LED lighting. This reduces the interference and therefore improves the performance of the device.

In addition, this filter also uses inductors to control the flow of current. When a current is flowing through an inductor, it creates an electromagnetic field, which then blocks or reduces the amount of noise. The use of the inductor is also beneficial as it helps to bypass unwanted noise and reduce EMI emission. This improves the performance of the device, as well as ensuring reliable operation.

To summarize, the PEMI4QFN/CM,132 is an EMI/RFI filter that belongs to the RC networks family. It is useful for reducing noise from switching power supplies, VCRs, consumer electronics, LED lighting and automotive electronics. The filter uses capacitors and inductors to control the current flow, thereby reducing the noise being generated and transmitted from electronic components. This ensures reliable operation and improved performance. This filter is thus an important component in today’s electronics industry.
