Kind inductance element and inductance element group.
Background technology
Ferrite highest frequency can reach 1MHz, and inductance value is big, and high-frequency loss is small.There are many materials at present for ferrite
Material and magnetic core specification, and price is lower than other materials, is widely used.
The electromagnetic component of open-flux path, magnetic line largely pass through air, and Magnetic Shielding Effectiveness is very poor, easy tos produce other
The magnetic force route of EMI radiation interference problems, closed magnetic circuit is most of without air, has the effect of magnetic screen, device is more steady
It is fixed.Existing H-type magnetic core easily automates, and coil number is more, but Magnetic Shielding Effectiveness is bad.
When electric current will produce magnetic field by coil, and in coil electric current increase by simultaneously magnetic field intensity also together
Increase, but this increase is not unlimited.After magnetic field reaches a certain limit in the magnetizer of coil, the enhancing of electric current
Similarly cannot magnetic field intensity be increased, it is known as " magnetic saturation ".When the magnetic circuit sectional area of material is bigger, the electric current flowed through
Smaller, coil turn is smaller, is just less susceptible to magnetic saturation；Otherwise when the magnetic circuit sectional area of material is smaller, the electric current flowed through is bigger,
Coil turn is bigger, is just more easy to reach magnetic saturation.Existing H-type magnetic core does not account for magnetic saturation and is brought to electromagnetism intensity
Influence.
