What are the inductive parameters?

First, the quality factor Quality factor:
The quality factor Q is a factor used to measure the relationship between the energy stored in an energy storage component (inductance or capacitance) and its energy consumption, which is indicated as: Q = 2π maximum stored energy / weekly lost energy. Generally, the larger the Q value of the inductor coil is, the better, but the stability of the working circuit is deteriorated.
Second, the inductance value Inductance:
When the current in one coil changes, the magnetic flux passing through the coil loop itself, which is changed by the changed current, also changes, causing the coil itself to induce an induced electromotive force. The self-inductance coefficient is a physical quantity that characterizes the self-induction of the coil. The self-inductance coefficient is also called self-inductance or inductance. It is indicated by L. Henry (H) is used as the unit, and one thousandth of it is called millihenry (mH). One in a million is called microhenry (μH), and the micro-henry is called a thousand-minor.
Third, DC resistance DC Resistance (DCR):
Inductance coils are measured under non-communication power. In inductor planning, the DC resistance is as small as possible. The measurement unit is ohm, which is generally indicated by its maximum value.
Fourth, self-resonant frequency Self-resonant frequency:
The inductor is not a purely inductive component. There is still a distributed capacitance. The resonance of the inductor itself and the distributed capacitance at a certain frequency is called the self-resonant frequency, also called the resonance frequency. Indicated by S.R.F., the unit is megahertz (MHz).
Fifth, the impedance value Impedance:
The impedance value of the inductor refers to the sum (complex) of all the impedances under the current, including the communication and DC parts. The impedance value of the DC part is only the DC resistance of the winding (real part), the communication part The impedance value contains the reactance (imaginary part) of the inductor. In this sense, the inductor can also be considered as a "communication resistor."
Sixth, additional current Rated current:
The continuous DC current strength of an inductor can be passed through. The strength of the DC current is based on the maximum temperature rise of the inductor at the maximum additional ambient temperature. The extra current and the inductance are reduced by the low DC resistance to reduce the winding loss. The ability is related to the energy loss of the inductor to dissipate the winding. Therefore, the extra current can be increased by lowering the DC resistance or increasing the inductance scale. For the low-frequency current waveform, the rms current value can be used instead of DC. The extra current, the extra current and the magnetic properties of the inductor are not tied.
