What is the Emi suppression ferrite core

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 suppression ferrite core

  • Ferrite Toroid Core
    RH series ferrite core is special customized product,with groove on the surface to put the cable after winding convenient, work frequency also cover 1mhz-1ghz, nizn is the common material.
  • Usb Ferrite Bead
    RH series emi suppression ferrite bead tube core commonly used for round cable for wire winding to get the anti-interference efficiency at high working frequency for application, especially at 1MHZ-500MHZ is the best condition, to fitted cable diameter from 1mm to 20mm.
  • Toroidal Ferrite Core
    R type ferrite core, is a rod shape Nickel Zinc or Manganese Zinc soft ferrite, commonly used for coils after winding with excellent withstand voltage and current,Rod coil inductor in igniter, carbon brush, audio antenna, wireless antenna widely used.
  • Ferrite Core Choke
    FS type ferrite core is a oval shape product, commonly used for flat digital cables for anti-jamming. Material is Nickel Znic, frequency cover 1mhz-1ghz, with best stable impedance at 1mhz-500mhz, curie temperature >160°C。
  • Ferrite Core Cables
    DR type soft ferrite core is a raw material for drum inductor coil which used for led light driver PCB board,this core with 2 pins,3pins or 4 pins to match the circuit board, it is dip inductor core. Material covered NiZn and MnZn power material.
  • Ferrite Core Noise Suppressor
    Dnh emi ferrite core is a NiZn customized size product, it is a RH tube core but with more than 3 cables through the core to get better impedance in special application.

Applications

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.

 

Pricing Guide

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.
