Fixed inductors refer to various inductors connected to an electronic circuit which are preset and permanent, resisting electrical current flow. Examples of fixed inductors are transistors, resistors, capacitors, inductors, and other components necessary for the function of a circuit. In the display industry, the HKQ04021N9S-T fixed inductor is widely used.

The HKQ04021N9S-T fixed inductor is an inductor employed to regulate the flow of electrical current in an electronic circuit. It is an extremely common commercial component, and is made of a round coiled metal wire that is soldered or attached to two terminals. It is constructed from metal wire wound in a evenly-spaced helical form that is threaded with spool and insulated with a varnish. Its size depends on the value of inductance.

The HKQ04021N9S-T fixed inductor has an inductance value of 4.0mhenry, a Q factor of 6.0, a rated current rate of 0.50A, and a rated voltage rate of 125V. The inductor has a tolerance of 10% or 5%, depending on the application. It is silver wound to create a low resistance value and to reduce parasitic capacitance. The inductor also features a ferrite core and a ferrite shield to ensure maximum inductance value and fewer losses due to core eddy current.

The application field of the HKQ04021N9S-T fixed inductor is mainly in display industry. Its primary uses include: in video processing, to reduce the radiowaves emitted and to enhance signals; in electro-mechanical systems, to limit the current surge; in smart phones, to block the interference to reduce the harm of electromagnetic radiation; in color TV receivers, to reduce interference; and in automobile electronics, to reduce the intake noise of automotive audio systems.

The working principle of the HKQ04021N9S-T fixed inductor is based on the basic principles of inductor design. When an alternating current (AC) is applied to an inductor, the magnetic field generated by the inductor causes electrical current to flow through the coil in the form of a loop. The magnitude of the induced current is determined by the magnitude of the magnetic flux. The inductor is essentially a transformer, converting alternating current to direct current.

The HKQ04021N9S-T fixed inductor is a great asset in the display industry due to its consistent electrical performance, reliable performance, and economical cost. With its extensive application field and simple working principle, it is a widely used part throughout the industry.
