ferrite core

Many electrical appliances like arc-welders, switching mode power supplies, electrical contacts and motor bushes can cause electromagnetic interference. The phenomenon occurs when the electromagnetic field of one appliance interferes with that of another one. This kind of interference can be harmful to the appliance itself and other electronic appliances nearby. A ferrite core is a solution to tackle this problem, and they can be found on Tradechina.com.

Power surges caused by electromagnetic disturbances can be disastrous to computer hardware, leading to corruption of data. A ferrite core is an effective way to counteract such disturbances. It can also be used to reduce frequency noise levels that occur due to the functioning of electromagnetic devices. The other component used for suppressing EMI is the ferrite toroid, which is similar to the core but has no air space and provides better protection. 

A very common place where one can see EMI is in USB cables. In such cases, a snap-on ferrite core or bead is used. This can reduce both EMI and RFI and improve signals. It is commonly used on other cables also like keyboard cable, mouse cable, headset wires, etc. Like a ferrite toroid, this is also made with ceramic that is integrated with ferric oxide. Both these products are available from many suppliers on Tradechina.com.

Suppliers on Tradechina.com also stock ferrite bits of various sizes. These are used to resist noise frequency levels more, beyond the normal tolerance. The ferrite core is also widely used in transformers. Customers can get them customized by the suppliers according to their requirements.
