PEMI2QFN/WT,115 Filters

EMI/RFI Filters (LC, RC Networks)

PEMI2QFN/WT,115 is an EMI/RFI filter specifically designed to suppress electromagnetic interference (EMI) and radio frequency interference (RFI) in power applications. It is a low pass filter made up of an inductor-capacitor (LC) network. The type PEMI2QFN/WT isolates a portion of the system from the EMI/RFI sources, allowing clean power to flow without interference.

Application Field

The PEMI2QFN/WT filter is designed for use in power supply units, electronic devices, and control systems, among other applications that require reliable power with insulation from external influence. It is the ideal solution for any application where very high levels of immunity against EMI and RFI must be achieved. PEMI2QFN/WT filters are used in power supplies, communications equipment, medical equipment, military equipment, and other applications with stringent EMI and RFI requirements.

Working Principle

The PEMI2QFN/WT EMI/RFI filter works by filtering out unwanted electromagnetic interference (EMI) and radio frequency interference (RFI) before it reaches the load. A low pass filter formed by an inductor-capacitor (LC) network creates a path for the clean power, while rejecting the interference. The filter is designed to meet specific levels of immunity against EMI and RFI, depending on the application, while offering high levels of isolation from EMI/RFI sources.

The PEMI2QFN/WT filter also has a high maximum working voltage, allowing it to handle high power levels. Its high maximum frequency makes it suitable for use in a range of applications and allows it to block even the highest frequency interference. This makes it an ideal solution for applications with very strict EMI/RFI requirements.

Conclusion

The PEMI2QFN/WT filter is an LC network-based EMI/RFI filter designed to provide reliable power with insulation from external sources. It is used in a variety of power supply units, electronic devices, and control systems to provide effective shielding against EMI and RFI. The filter has a high maximum working voltage and a high maximum frequency, allowing it to handle high power levels and block even the highest frequency interference. As such, it is a suitable solution for any application with stringent EMI and RFI requirements.
