Common mode chokes (CMCs) are the most important and widely used components in power electronics today. They are utilized for magnetic noise suppression, noise shielding, and anti-interference, as well as for electromagnetic compatibility (EMC) related tests. The DKIL-0346-20D6 is one such CMC device from a leading manufacturer. This paper will discuss the application field and working principle of this device in detail.

DKIL-0346-20D6 is primarily used for suppressing radiated and conducted interference in high frequency power applications that include digital circuits, LEDs, and switching power supplies. It is designed to be used when a tight magnetic field is needed, and its ability to operate over a wide frequency range makes it one of the most versatile CMCs on the market. It is also ideal for internal control systems and instrumentation-based applications due to its low core material losses.

The DKIL-0346-20D6 Common Mode Choke features two windings arranged in a twisted shape. This kind of construction improves the core linking coefficient, and reduces leakage flux as compared to a traditional common mode choke with a single winding. It also has a high permeability ferrite core that enables the device to generate a high inductance. Moreover, this device has a high saturation current and a low DC resistance, making it suitable for power applications.

The working principle of the DKIL-0346-20D6 CMC is based on the principle of inductance. It works by creating a magnetic field around the core when an alternating current is applied to the windings. This field restricts the flow of electric current which can help in suppressing noise signals. It can also be used to keep different impedance levels between the source and the load that are connected by the CMC.

In summary, the DKIL-0346-20D6 is an ideal CMC device for use in high frequency power applications such as LEDs, digital circuits, and switching power supplies. It is designed with two windings to improve its permeability and core linking coefficient. Moreover, it has a low DC resistance and a high saturation current which makes it suitable for power applications. The working principle of this CMC is based on the principle of inductance which makes it useful for noise suppression and electromagnetic compatibility tests.
