EMI/RFI filters, such as LC, RC networks, are used in a wide range of applications to reduce the emission of electromagnetic and radio frequency interference (EMI/RFI) from electronic devices. One such filter is the PEMI2QFN/HP,115 filter, which is designed to reduce emission of high-frequency noise in high-power applications. This article will discuss the application field and working principle of the PEMI2QFN/HP,115 EMI/RFI filter.

The PEMI2QFN/HP,115 is a high-performance EMI/RFI filter designed to reduce noise emissions in applications requiring high power. It is suited for use in cellphones, consumer electronics, radio communication systems, medical devices, and other consumer products that are subject to international or national EMI/RFI emission regulations. In addition, due to its high power density, the filter is suitable for applications with space constraints, such as cellphones. The filter can also be used in military and aerospace applications where high power is required and space is limited.

The PEMI2QFN/HP,115\'s efficient filtering mechanism is based on a combination of symmetrical and asymmetrical anisotropically conducting shielding. The shield is an array of three elements - the outermost is a metal foil screen, while the inner two are formed from carbon nanotubes. Magnetic materials, such as ferrites, are used to encourage the absorption of EMI/RFI emitted from inside the device, while the carbon nanotubes provide an effective shield against external RFI signals. This combination of shielding allows the filter to effectively block both conducted and radiated EMI/RFI emissions.

The filter also features an additional shielding material, which is applied directly to the printed circuit board. This shielding is designed to reduce RFI emissions from the board itself and to absorb any noise that makes it past the anisotropically conducting shield. This additional shielding helps to further reduce the amount of EMI/RFI that is produced by the device.

The PEMI2QFN/HP,115 has a few other features that make it an attractive option for high power applications. It is designed to operate over a wide temperature range, from -55°C to +125°C, meaning it is able to handle high duty cycles and environments with rapidly changing temperatures. In addition, its low insertion loss makes it ideal for applications that require tight control over power consumption.

The PEMI2QFN/HP,115 is a reliable and effective EMI/RFI filter that is suitable for a wide range of high-power applications, including military and aerospace. Its combination of shielding materials and features make it an attractive choice for applications where noise emissions must be kept to a minimum. The low insertion loss of the filter ensures that it does not unduly impact power consumption, and its wide temperature range makes it suitable for a range of environments.
