EMI/RFI filters are widely used in the fields of communication, defense, electronics, and metrology, to suppress EMI/RFI interference. The 4700-003MLF is one of the most popular filters in this family. It is a low pass LC filter with two terminals and three inductors. It is designed for use in high frequency applications and provides excellent performance.

The 4700-003MLF features three inductors with a characteristic impedance of 100 ohms, which ensures a higher quality of signal transmission in the frequency range of 1MHz to 100MHz. The filter offers an impressive 40dB of attenuation at these frequencies and is designed to suppress EMI/RFI noise from the input signal. The filter also features high voltage transient suppression, which ensures that the signal does not bounce or distort at high frequencies.

The key features of the 4700-003MLF are its high frequency performance and high voltage transient suppression. The small size of the component also makes it ideal for applications where space is limited. The filter can be used in communication systems, high frequency signal processing devices, audio signal processors, and other applications. It is also suitable for use in a variety of industries, including automotive, medical, aerospace, and military applications.

The working principle of the 4700-003MLF is based on the use of three inductors in series. Each inductor is connected in parallel with a capacitor, creating a high-frequency \'loop\'. This high-frequency loop filters out any EMI/RFI interference that may be present in the input signal, allowing only the desired signal to pass through. The attenuation characteristics of the filter depend on the value of the inductors and capacitors, as well as the number of inductors.

The 4700-003MLF is an effective and reliable filter for suppressing EMI/RFI interference in a variety of applications. It offers excellent performance and can be used in a variety of industries and applications. It is also relatively small in size and therefore suitable for applications where space is limited. The filter is well suited for high frequency signal processing, audio signal processing, and other applications, and its high voltage transient suppression ensures that the signal does not bounce or distort at high frequencies.
