ferrite magnets
1 Supply lighting, transformer MnZn core
2 Used in anti-interference electronics
3 high quality ROHS ap
coated Toroidal  ferrite  Core ,Mn-zn magnets,  ferrite  magnets made of Mn-Zn
 Features:
1. This kinds of toroid  core be used in anti-interference electronic circuit components, such as transformers, lighting, ballast, etc, it is powder coating
2.the high-frequency noise has a good inhibitory effect,
3.it’s made the general use of ferrite materials Mn-Zn(manganeso-Znic ),pc40 or pc95, import from TDK Japan
4,the Mn-zn magnets be widely used in  energy- saving light, switching power
5, we promised that if you buy our toroid ferrite core ,you will never change supplier again,  most important is  our ferrite core 's character very stable in any tempreture condition
Quality  has passed  iso9001, ccc, CE, ROHS .
6,material; Mn-zn
we would like to introduce ourself as a reliable  suppliers of film capacitor & toroidal  transformer  cores. there are more than 15 years working experience  in this filed.we have winned lots of customers due to high quality . like "opple" Foshan lighting , oudior, TDK( Japan).
How to choose the number of turns ring?
The whole bundle of cable through a ferrite bead to form a common mode choke, if necessary, can also be above the cable around a few turns in the ring. The more turns, the lower the frequency the better interference suppression, and inhibition of weak high frequency noise.
In the actual project, according to the frequency of interference current to adjust the magnetic characteristics of the number of turns.
Note :
1. If any of our  transformer core is  interested  to you, please inquiry me at anytime.
2.sample of ferrite core is free of charge, please contact me
3, our ferrite cores are mainly used  in lighting, the quality is promised. feeel free to purchasing.
