Core procurement

    The magnetic core is composed of a soft ferrite material with a monolithic structure with high volume resistivity. Eddy current loss is inversely proportional to resistivity, and eddy current loss is proportional to the square of the signal frequency.

    The function of the magnetic core is mainly to eliminate the RF noise that exists in the transmission line structure. The DC component is the useful signal and the radio frequency RF energy is useless electromagnetic interference along the line Transmission and radiation. To eliminate these unwanted signal energy, the chip plays the role of high-frequency resistance. The device allows DC signals to pass and filters out AC signals.

    Magnetic cores are used to absorb ultra-high frequency signals, such as some RF circuits, PLLs, oscillator circuits, and ultra-high frequency memory circuits that require a magnetic core in the power input part. The inductor is a kind of energy storage element used in LC oscillation circuit, medium and low frequency filter circuit and so on.

    Magnetic core: apply glue to the middle part of the shaft core-magnetic block and shaft core are placed in the mold and compacted-put into the mold and magnetized-magnetic force detection (to be completed Assembly)

    Magnetic core: Magnetic core refers to a sintered magnetic metal oxide composed of various iron oxide mixtures. For example, manganese-zinc ferrite and nickel-zinc ferrite are typical magnetic core materials. Manganese-zinc ferrite has the characteristics of high magnetic permeability and high magnetic flux density, and has low loss characteristics at frequencies below 1MHz. Nickel-zinc ferrite has the characteristics of extremely high resistivity, low permeability of less than a few hundred, and low loss at frequencies higher than 1MHz. Ferrite cores are used in coils and transformers of various electronic devices
