Inductance is what concept?
The inductance of the inductor, the allowable deviation, the quality factor, the distributed capacitance and the rated current.
The coil core than the coil inductance without core coil core permeability volume; the greater the inductance is greater.
Usually, the more coils, the more dense the winding, the greater the inductance.
Inductance inductance of the size, mainly depends on the number of coils (turns), winding method, with or without the core and core materials, etc.
