विवरण

• Toroidal cores are passive electronic ingredients consisting of a round ring or donut-shaped magnetic core of ferromagnetic ferrite around which wire is wound Specification: Color: Black Material: Nickel Zinc Ferrite Squareness Ratio: 10 Bs: 400T Br: 150mT Tc: 120°C Hc: 13A/m ρ: 4/cm3 μi: 650-1000 Packing List: 10 x Toroids Advantage: Ferrite cores are dense, homogeneous ceramic constructions made by blending iron oxide (NiZnFe2O4) with oxides or carbonates of nickel, zinc Have very excessive permeability and coffee losses, can work at excessive frequencies Instruction: Used to suppress electromagnetic emissions by way of blockading low-frequency noise and absorbing high-frequency noise, fending off interference Widely used in EMI/RFI filters, audio transformers, communications, control circuit equipment, LED lighting, car electronics, commercial control, etc NOTE: The more the variety of coiled cables, the better the effect of suppressing interference with decrease frequencies, the weaker the impact of suppressing noise with higher frequencies
