The current rating is the operating current of an inductor and it is measured in Amps.

Less the power loss greater will be the quality of the coil.

The loss in the coil is due to the copper wire, stray capacitance, and resistance of the coil. For a good coil, Q must be high and R must be below. It is the ratio of inductive reactance (XL) to the resistance (R) of the coil. The reciprocal of the power factor is the quality factor. The frequency range is the maximum frequency up to which the inductor can work safely. a coil has some capacitance between windings which is called a stray capacitance. Stray capacitance effect exists in an inductor, i.e. Resistance is the ohm value of an inductor wire, which is expressed in ohms. The value of inductance is measured in terms of its inductance value and is expressed in henries, millihenries, and microhenries.
