Common mode chokes are electrical components that provide a low impedance for currents at certain frequencies while allowing very little impedance for currents at other frequencies.The RFCMF1220100M3T application field and working principle is an example of a common mode choke.

This choke provides a high impedance for certain frequencies in the range from 0.39MHz to 68MHz. This makes it ideal for applications in controlling electromagnetic interference (EMI) since it can effectively filter obtrusive frequencies, making it beneficial for EMI interferers and radio-applied environment.

The working principle of the RFCMF1220100M3T is based on the same principle that allows a normal transformer to function as an isolated power source. According to this principle, a current passing through one of the windings creates an electromotive force in the other winding. This can be used to power a circuit. In the case of the RFCMF1220100M3T, the principle is applied in reverse. In this case, a current passing through one winding will induce an equal current in the other winding, rather than creating an electromotive force. This creates a high impedance for the frequencies in its specified range, and this can be used to filter EMI and RF signals.

The RFCMF1220100M3T is also available in both bulk and adjustable options. The adjustable option is preferred for when a precise setting of frequencies needs to be filtered since it allows for precisely tuning the choke to the desired settings. This makes it even more effective at blocking interference.

The RFCMF1220100M3T is easy to install and, in addition to its filtering ability, it also adds some voltage isolation that will also help in blocking interference. This makes it an ideal choice for applications that involve filtering out EMI and other unwanted frequencies in order to ensure consistent operation in critical electronic systems.

In conclusion, the RFCMF1220100M3T application field and working principle explain how the choke can be used to effectively filter out certain frequencies in order to reduce EMI interference. The RPCM structure with its adjustable option makes it a versatile choice that can be used in a variety of applications.
