2021 High quality Common Mode Choke Design - Power line common mode choke – Mingda
2021 High quality Common Mode Choke Design - Power line common mode choke – Mingda Detail:
Power line CM chokes achieves high suppression of asymmetric interferences, even at low frequency ranges. Do not underestimate the parasitic effects when using common mode chokes. This was the most important point to reduce these dues when developing the WE-CMB series. The perfect core / winding-ratio enables very-high currents at comparable areas, anyhow the inductance is sufficient. The adjusted wire gauge realizes low heating.
Advantages:
1. Very compact design
2.Customized the product according to the basic information from your engineers. Quick sample lead time.
3.High levels of safety and reliability
4. Filtering common mode electromagnetic interference signals
5.Useful for application requiring inductance to vary with current load changes.
6.Self electromagnetic shielding. Easy PC board mounting Conversion application.
7.Build to ROHS compliance.
Autually the common mode inductor is essentially a two-way filter: on the one hand, it must filter out common mode electromagnetic interference on the signal line, and on the other hand, it must suppress itself from emitting electromagnetic interference to avoid affecting the normal operation of other electronic equipment in the same electromagnetic environment.
Common-mode inductors have extremely high initial permeability, large impedance and insertion loss under the earth’s magnetic field, and have an excellent suppression effect on interference, and exhibit resonance-free insertion loss characteristics in a wide frequency range. High initial permeability: 5-20 times that of ferrite, so it has greater insertion loss, and its suppression effect on conduction interference is much greater than ferrite.
