EMI/RFI filters are electronic components that help limit electromagnetic interference in an electronic circuit. The PEMI6QFN/HE, 132 filter is one such type of EMI filter. By understanding its application field and working principle, users can incorporate this filter into their electronic devices, ensuring the highest level of electromagnetic compatibility possible.

Application Field

The PEMI6QFN/HE, 132 filter is designed to reduce unwanted noise from two sources. The first is Electro-Magnetic Interference (EMI) noise. This type of noise is generated by external sources such as radio towers, lighting systems, and power sources. It is commonly referred to as “electro-magnetic noise” or “radio noise” and can cause disruption of normal operations if left unchecked. The second source of unwanted noise is conducted Electromagnetic Interference (RFI). This type of noise is generated by external sources such as power supplies, lighting systems, and motors. It is commonly referred to as “radio frequency noise” or “conducted noise” and can also cause disruption of normal operations if left unchecked.

The PEMI6QFN/HE, 132 filter can effectively reduce the unwanted EMI and RFI noise from external sources. As such, this filter is suitable for use in a variety of applications, including automotive, industrial, medical, and consumer electronics. Additionally, the filter can be used in military and aviation systems to reduce EMI and RFI noise to military specifications.

Working Principle

EMI/RFI filters typically consist of two components: a capacitor and an inductor. The capacitor and inductor act together to form a low-pass filter, which blocks unwanted RF noise while allowing desired signals to pass through. The PEMI6QFN/HE, 132 filter also employs additional circuit elements, such as resistors and capacitors, to achieve a high level of noise reduction for both EMI and RFI noise sources.

When RF noise strikes the filter, it is divided into two paths. The first path is blocked by the inductor, which prevents the RF noise from passing through and reaching its destination. The second path is routed towards the capacitor, which stores the energy from the RF noise and passes it back into the power source. The capacitors then release the energy in the form of an inverted wave. This inverted wave cancels out the noise, thus ensuring the desired signals can pass through the filter un harmed.

The PEMI6QFN/HE, 132 filter also employs additional circuit elements, such as resistors and capacitors, to achieve a high level of noise reduction. Together, these components allow the filter to provide a comprehensive solution for EMI/RFI noise reduction in a variety of applications. By using the PEMI6QFN/HE, 132 filter, users can ensure their devices are best protected from unwanted EMI and RFI noise.
