factory wholesale good quality chinese Common mode inductors
Common mode filter inductance magnetic core
Characteristics
High initial permeability; and has strong resistance and insertion loss; can greatly suppress weak interference; and has no-resonance insertion loss during a wide frequency range.
a. High initial permeability: it is about twice or three times of ferrite. So it has much stronger insertion loss and suppression of conducted interference of it is much stronger then ferrite.
b. High saturation magnetic induction, about twice or three times of ferrite. And it is hard to magnetize to saturation when there is an interference of electric current.
c. Great temperature stability: The change of characteristic of alloy is obviously lower than ferrite when there is high curie temperature and big change of temperature. It has great stability and the curve of characteristic change is about a straight line.
d. Flexible frequency: can flexibly change the process to get the needed frequency. And can get different resistance with different process and suitable coils to satisfy the filter in different wave band, and this can make its resistance much stronger than ferrite.
Application
Electric network common-mode interference filter
Electronic equipment and instrument an-impact interference
