Common Mode Chokes (CMCs) are used to reduce the amount of interference produced by electrical circuits or systems. The FE2X15-4-2 is a specific type of CMC designed for superior performance in a variety of applications. This article will explore the application field and working principle related to this particular CMC.

The FE2X15-4-2 operates on the principle of electromagnetic interaction between the inductor and the external environment. It is designed to absorb current and attenuate emission of EMI (Electromagnetic Interference). When two coils, or inductors, are driven in parallel with different input signals, they interact with each other due to their mutual inductance. This interaction reduces the total current flowing through the inductor, producing a common mode current across the inductor. The CMC will effectively attenuate the EMI emission in the frequency band where its current peak occurs.

The FE2X15-4-2 has a wide range of applications. It is primarily used in power electronics and signal processing devices, such as AC and DC motors, SMPS (Switch Mode Power Supplies), power filtering, and in the telecommunications and medical industries. It is also suitable for embedded, industrial, and consumer electronics. It is designed to achieve high power handling capacity and a wide range of current ratings.

The FE2X15-4-2 is also suitable for automotive applications. It is designed to withstand harsh environments, high temperatures, and vibrations. It provides superior protection from EMI in a number of electronic devices used in automobiles. It is also suitable for military applications, as it can be used to improve signal integrity for complex signal processing systems.

The working principle of the FE2X15-4-2 is straightforward. The CMC utilizes a pair of specially designed coils to suppress EMI. They are driven in parallel with different input signals, resulting in an interaction between the inductors due to their mutual inductance. As a result of this interaction, the total current flowing through the inductor is restricted, producing a common mode current across the inductor. This common mode current is then effectively attenuated, reducing emissions of EMI in the frequency band where its current peak occurs.

In conclusion, the FE2X15-4-2 is a highly versatile CMC suitable for a wide range of applications, including power electronics, signal processing, and automotive use. It operates on the principle of electromagnetic interaction between the inductor and external environment, which reduces total current flowing through the inductor and attenuates EMI emissions. This makes the FE2X15-4-2 an ideal solution for improving signal integrity and reducing EMI.
