Fixed Inductors

Fixed inductors are used in a wide variety of electronics including resonators, power supplies, and wireless communication. A fixed inductor is an inductor that does not change its characteristics regardless of the changes in current. This makes them ideal for applications requiring consistent behavior, such as filtering radio frequencies or suppressing strong oscillations. Fixed inductors are typically found within applications involving DC-DC converters and voltage regulators.

The HKQ04023N5S-E is a typically used fixed inductor with a high frequency of 10MHz and a DC resistance of 10mΩ. The inductance tolerance is 10%, with a maximum resistance of 4Ω. The product is composed of copper wire wound into a core, with the standard package being a 9.7x12.7 mm surface mounted footprint in an open frame configuration. The operating temperature range is -55° to +105° C.

Application Field and Working Principle

The HKQ04023N5S-E is mainly used for the integration of the power inductors, resonators, and base station antennas. The high efficiency and wide frequency range of the products makes them suitable for use in radio frequency and analogue component integrated designs. They are also commonly used as starting components of multi-layer inductors for power supply applications.

The operating principle of the HKQ04023N5S-E is based on the principles of electromagnetic induction. Electromagnetic induction is the production of an induced electrical current or voltage when an electric current is passed through an inductor. The induced voltage is proportional to the rate of change of the current passing through the inductor. The magnitude of the induced voltage is determined by the amount of the magnetic field generated by the inductor, and the rate of change of the magnetic field produced by the current through the inductor.

The magnitude of the current passing through the inductor determines the number of turns of the wire wound around the inductor core. This determines the self-inductance of the inductor, which is the opposition to any change of current. This also subsequently determines the frequency that the inductor can resist without the current passing through the inductor changing.

The HKQ04023N5S-E is designed with an air gap in the core that can be adjusted, allowing the inductance to be adjusted accordingly. This contributes to the adjustable frequency range of the fixed inductor, allowing the possibility of use in various wireless applications.

The HKQ04023N5S-E is a fixed inductor designed for use in a variety of applications including resonators, power supplies, and wireless communications.
