ferrite toroidal core

Product Description

Features:

Toroidal ferrite  Core (H*2*7*5 )Green

ferrite core  toroid core  made of Mn-Zn be coated

1. This kinds of ferrite 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 )

4,ferrite core be widely used in  energy saving light

5, we promised that if you buy our toroid ferrite core ,you will never change supplier again

cores at different frequencies have different impedance characteristics, the general impedance at low frequencies is small, magnetic performance when the signal frequency increases the impedance dramatically.

We all know that the higher the frequency, the more easily radiate. And general signal lines are no shield, then the signal line to become a good antenna to receive all kinds of clutter in the surrounding environment of high frequency signals, these signals are superimposed on the original transmission of the signal, or even change the original transmission of useful signals.

we would like to introduce ourself as a reliable  suppliers of film capacitor & toroidal  ferrite cores. there are more than *5 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.
