Electromagnetic Induction Coil,
Black Electromagnetic Induction Coil
The inductance L represents the inherent characteristics of the coil, independent of the current. In addition to the special inductance coil (color coded inductance), the inductance is generally not specially marked on the coil, but marked with a specific name.
The size of the blocking effect of inductance coil on AC current is called inductance XL, and the unit is Ohm. Its relation with inductance L and AC frequency f is XL = 2 π FL
Quality factor Q is a physical quantity indicating the coil quality. Q is the ratio of inductive reactance XL to its equivalent resistance, that is, q = XL / R.
The higher the Q value of the coil, the smaller the loss of the loop. The Q value of the coil is related to the DC resistance of the conductor, the dielectric loss of the frame, the loss caused by the shield or iron core, and the influence of the skin effect of high frequency. The Q value of the coil is usually tens to hundreds.
The capacitance between turns of coil, between coil and shield, between coil and substrate is called distributed capacitance. The existence of the distributed capacitance makes the Q value of the coil decrease and the stability become worse, so the smaller the distributed capacitance of the coil, the better.
