Common Mode Chokes (CMChs) are inductive components used in power systems to reduce or avoid distorted waveforms, reduce conducted and radiated emissions, suppress voltage transients and protect power components from damage caused by EMI. The DKFP-0276-0207L is a type of CMCh specially designed to meet the demands of sophisticated power systems.

The core of the DKFP-0276-0207L is constructed with Ferrite material and encapsulated by an environmentally-friendly, flame retardant epoxy material. The two cores have multiple windings of copper conductor in bifilar electrically and magnetically connected.

The primary application field of the DKFP-0276-0207L is magnetically coupled power converters, and their operating environment is relatively stable. This product is also suitable for the power distribution system of the internal system architecture layout such as motherboard applications. It has a wide operational temperature range of -40°C to 125°C.

The operating principle of the DKFP-0276-0207L Common Mode Choke is based on the common mode impedance, where the external magnetic field induces a common mode voltage across the edges of the two bifilar windings.

The inner part of the CH is composed of a core material and two bifilar windings separated from each other by an air gap. When electric current flows in both windings, it creates a magnetic flux, which accelerates from one winding to the other winding. The escape of flux current from one winding induces a common mode voltage on the other winding, which is capable of suppressing common mode noise. As a result, this CMCh is suitable for applications where different power types are used to suppress common mode noise.

DKFP-0276-0207L Common Mode Choke also offers several features: wide definition range, low additional insertion loss, low leakage inductance, high insulation performance, and high insertion reliability.

Due to its superior properties, the DKFP-0276-0207L Common Mode Chokes are widely used in power systems to reduce distortion of waveforms and suppress voltage transients. They are also used to suppress conducted and radiated emissions, provide protection from EMI and help keep systems running in an efficient manner.
