Trilogy of inductors pdf to word5/31/2023 The 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. The stray capacitance effect exists in an inductor, i.e., a coil has some capacitance between windings called a stray capacitance. 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. Temperature coefficient 1) Inductance value:.Read also: What are different types of AC motors? Specification of Inductors These inductors are used in line filters, filter designs, and boost converters. ![]() ![]() ![]() The inductor goes through a molding process where the values are printed as colored bands, so just like a resistor, the value is determined by comparing the bands with a color code chart. When an unstable current is passed through it, it produces a transfer magnetic field, and this magnetic field affects the current. An inductor of this type is made by wrapping thin copper wire around a dumbbell-shaped ferrite core and connecting two lids at the top and bottom.
