ELK-E471FA Application Field and Working Principle

EMI/RFI Filters (LC, RC Networks) are electrical devices that reduce the intensity of electromagnetic interference (EMI) or radio frequency interference (RFI) in electronic circuits. The ELK-E471FA Filter is a typical such device in this category, and it is specially designed for protection in the aerospace industry. The following sections discuss the application field and working principle of the ELK-E471FA Filter.

Application Field of ELK-E471FA Filter

The ELK-E471FA Filter is an advanced version of the traditional EMI/RFI filter and has the following features:

• Low pass filter
• Wide operational frequency range
• Low insertion loss
• High attenuation

These features make the ELK-E471FA Filter an ideal choice for protecting sensitive electronic devices from electromagnetic interference in the aerospace industry. The filter can be used to provide EMI/RFI protection to radar systems, fiber optic systems, communication systems, and video equipment, as well as in other high-frequency applications. Additionally, it is suitable for installation in high-altitude aircraft, where the electromagnetic interference is more intense.

Working Principle of ELK-E471FA Filter

The ELK-E471FA Filter is a low pass filter, which reduces the amplitude of high-frequency signals and passes low-frequency signals. It works by using capacitors and inductors to form two LC (inductor-capacitor) networks, which react differently to signals of different frequencies. The first LC network is the passband, which passes signals of low frequency and attenuates signals of high frequency. The second LC network is the stopband, which blocks or attenuates signals with frequencies higher than the passband. By properly setting the values of the capacitors and inductors, the filter gives excellent attenuation in the stopband and low reflection in the passband.

The ELK-E471FA Filter is also designed with an integrated ESD filter, which provides added protection against static discharges. This ensures that the sensitive electronic devices connected to the filter are protected from the damaging effects of electrostatic discharge. Additionally, the filter also uses surge protection circuitry to protect against sudden surges of electrical current.

Conclusion

The ELK-E471FA Filter is a low pass filter, specifically designed for use in the aerospace industry, and it is suitable for use in high-altitude aircrafts. It is designed with LC networks, ESD filters, and surge protection circuits to provide the highest possible levels of EMI and RFI protection. Thus, it is an ideal choice for protecting sensitive electronic devices in the aerospace industry.
