PLA10AN9012R0D2B

Common Mode Chokes (CMCs) are more popularly known as common mode inductors, which are integral passive components in the production of switching power supplies. The PLA10AN9012R0D2B is a type of CMC designed for DC applications, and is made from nanocrystalline cores wrapped in two ferrite cores to reduce magnetostriction. The magnetic flux generated by the cores is used to reduce common mode noise and interference in the power supply.

The PLA10AN9012R0D2B utilizes a three-phase common mode choke design, which utilizes a combination of winding-to-core geometry, self minus and common-to-differential capacitance, as well as inductance components, to achieve optimal noise filtering. In addition, it also employs shielded outputs to provide additional electromagnetic interference (EMI) attenuation, ensuring that only the desired filtered signals are output to the load.

The application field of PLA10AN9012R0D2B is mainly in DC power supplies, which are used in a wide range of commercial and industrial applications. These power supplies typically require a high degree of isolation between input and output, as well as high frequency noise of more than 50MHz. The PLA10AN9012R0D2B is specifically designed to be used in DC power supply applications, and is capable of handling currents up to 20A, and voltages as high as 400V.

The working principle of the PLA10AN9012R0D2B CMC starts with the input noise, where the random high frequency noise is filtered out by the transformer winding-to-core geometry. The EMI attenuation is then accomplished by shielding the outputs and using the self minus and common-to-differential capacitance. Finally, the inductance component is used to filter out the remaining high frequency components, allowing only the desired signals to be output to the load.

In summary, Commission Model Chokes are integral components in communications and electronics systems and the PLA10AN9012R0D2B is a 3-phase common mode choke that is specifically designed for DC power supply applications. It utilizes a combination of winding-to-core geometry, self minus and common-to-differential capacitance, and inductance components to achieve optimal noise filtering. It is capable of handling currents up to 20A, and voltages as high as 400V, providing excellent noise filtering performance and EMI attenuation characteristics.
