Emi suppression ferrite core is a electrical component that used for Anti-interference between cables and terminal, materials covered Magnesium-Zinc(MgZn), Nickel-Ziinc(NiZn) and Manganese Zinc(MnZn). These ferrites include the model as ferrite toroidal, ferrite ring,ferrite tube,ferrite rod,ferrite bead,ferrite drum core,balun ferrite core ,flat ferrite,ferrite disc,ferrite clamp core, split ferrite with plastic case,snap ferrite ,SMD ferrite core,most of them used for HDMI cable, Power cable, VGA cable, USB cable,DVI cable,AVI cable for noise or rf suppression, but some of ferrites also application in making inductor, RF transformer, balun transformer,filters, NiZn ferrite core working frequency from 1Mhz-1Ghz and MnZn ferrite core from 10Khz-1Mhz with lower core loss factor.
EMI: Electro Magnetic Interference
EMC: electromagnetic compatibility

Emi suppression ferrite core have a wide range of applications as follows:
Electrical appliances components, on cables of TV, Washing machine, Air-conditioning, refrigerator, rice cooker,printer.
Communication industrial, cell phone, wireless charger, audio antenna, connector,TV set-top box.
Automobile industrial, Igniter, Airbag, carbon brush,
Medical Machine, many electrical inspection machines.
Most of the EMI ferrite used for on cables, filter inductor coils, RF transformers, common mode chokes, sensors,DM inductor.
EMI suppression ferrites produced with different raw material with different price, that based on the permeability from 80-1500, common material is F2 and F9 material with most cost-effective, and we can produce with different materials according to customer’s requirements.
The price also different in different countries, because the cost for customs clearance, tax, local cost and services are different.
1. Consult:
We will recommend customer provide the size, include the out diameter, inner diameter, and height, and the impedance value requirement, material, quantity, also the drawing of the products if customer require customized.
