High power induction antenna coil

Main features of high power induction antenna coil: ideal DC-DC conversion inductance, high power high saturation inductor, small DC resistance, suitable for high current, tape or reel packaging for automatic surface mounting, NFC coil for power supply equipment, vehicle communication equipment, LCD TVs, mobile communication equipment, laptop computers, office automation equipment, medical communication equipment, DC\/DC converters, etc.

The high-power induction antenna coil is composed of several windings wound on the magnetic core, and uses the principle of electromagnetic induction to work. The overall cross-sectional area of ​​the winding meets the requirements of the current carrying capacity, and at the same time, the winding loss caused by the skin effect can be reduced. The inductance is the main target parameter for the design of the inductance coil, which can provide high impedance for the high-frequency current signal, thereby suppressing the interference current. There is parasitic capacitance between winding and winding, winding and magnetic core, which affects its high-frequency impedance, thereby reducing the high-frequency filtering performance of the inductive coil. Therefore, the calculation of the inductance and distributed capacitance of the multi-wire parallel winding inductance coil is suitable for the high-power EMI filter. Research is especially important.
