Common Mode Chokes are components used to effectively suppress electromagnetic interference (EMI) radiating from high frequency power electronic circuits. The RD6127-10-9M0 is a common mode filter employed in the EMI suppression of electrical systems, such as data communications, robotics and industrial, lighting and aerospace applications. This component effectively protects against high frequency noise generated by both symmetrical and asymmetrical balanced transmission lines.

The RD6127-10-9M0 is specifically designed for noise attenuation in low voltage DC-DC converters (<200V DC). The low profile filter mounting reduces the effect of air space impairments. It also provides an effective shield between the power tube and the die to reduce crosstalk effects. The filter also incorporates an in-built capacitor, allowing it to withstand higher temperature and vibration levels, while providing a superior electromagnetic interference (EMI) suppression level.

The RD6127-10-9M0 utilizes two sets of windings (primary and secondary) to filter common mode noise. It works in the following manner: the primary winding, when energized, will create high magnetic field strength. When the high frequency current passes through the secondary winding, it will establish a reciprocal signal, resulting in a cancellation of the noise in the transmission line. Within each of the primary and secondary windings, the distributed capacitance experienced by the inductive core creates low impedance paths, allowing the common mode noise to exit to ground.

The RD6127-10-9M0 utilizes a semi-shielding technique to reduce the leakage of high frequency noise. This technique is accomplished by winding the primary and secondary windings in the opposite direction to that of the internal ground. This approach will help to prevent the leakage of high frequency noise from the component. The internal ground also reduces the buildup of high voltage induced by the winding.

The RD6127-10-9M0 is suitable for a wide range of applications, such as in data communications, home entertainment systems, medical imaging equipment, automotive applications, lighting, industrial automation, and aerospace applications. It is also a great choice for high frequency power electronic circuit protection and EMI suppression.

In summary, the RD6127-10-9M0 is a common mode filter specifically designed for EMI suppression in low voltage DC-DC converters. It is equipped with two sets of windings (primary and secondary) to filter common mode noise. This is done by creating a reciprocal signal in the secondary winding, which results in a cancellation of high frequency noise. The filter also incorporates an in-built capacitor enabling it to withstand higher temperature and vibration levels, while providing superior electromagnetic interference (EMI) suppression. It is suitable for a variety of applications, including data communications, home entertainment systems, medical imaging, automotive applications, professional lighting, industrial automation, and aerospace applications.
