20 Pack Ferrite Toroid Cores Set Transformer Inductor Coil Ring Black 5 Sizes

Description: Toroidal cores are passive electronic components consisting of a circular ring or donut-shaped magnetic core of ferromagnetic ferrite around which wire is wound.SpecificationColor: BlackMaterial: Nickel Zinc FerriteSquareness rate: 10Bs: 400TBr: 150mTTc: 120°Cρ: 4.9g/cm3μi: 650-1000Outer Diameter: 17.5mm/0.69 inch, 18mm/0.71 inch, 20mm/0.79 inch, 22.5mm/0.89 inch, 25mm/0.98 inchInner Diameter: 9.5mm/0.37 inch, 10mm/0.39 inch, 10mm/0.39 inch, 13.8mm/0.54 inch, 15mm/0.59 inchThickness: 12.7mm/0.5 inch, 10mm/0.39 inch, 10mm/0.39 inch, 10mm/0.39 inch, 12mm/0.47 inchPacking List: 20 x Toroids (4 Pieces For Each Size)AdvantageFerrite cores are dense, homogeneous ceramic structures made by mixing iron oxide (NiZnFe2O4) with oxides or carbonates of nickel, zinc. Have very high permeability and low losses, can work at high frequencies.InstructionUsed to suppress electromagnetic emissions by blocking low-frequency noise and absorbing high-frequency noise, avoiding interference. Widely used in EMI/RFI filters, audio transformers, communications, control circuit equipment, LED lighting, automotive electronics, industrial control, etc.NOTEThe more the number of coiled cables, the better the effect of suppressing interference with lower frequencies, the weaker the effect of suppressing noise with higher frequencies. 20 Pack Ferrite Toroid Cores Set Transformer Inductor Coil Ring Black 5 Sizes Toroidal cores are passive electronic components consisting of a circular ring or donut-shaped magnetic core of ferromagnetic ferrite around which wire is wound.
