Fixed inductors are electronic components designed to store energy in the form of a magnetic field in an electrical circuit, using a stationary core instead of a movable core, such as a coil or capacitor. A fixed inductor, such as the HKQ04023N7S-T, has specific application fields and working principles.

The HKQ04023N7S-T is a surface-mountable, 4-pin fixed inductor with a rated current of 2.3A and an inductance value of 0.40mH. It has a maximum DC resistance of 0.12 Ohm, and a maximum SRF (self-resonance frequency) of 6.6MHz. It also has a maximum DC current saturation of 4.3A and a maximum AC current of 5.2A.

The HKQ04023N7S-T is widely used in applications that require higher power handling capability and where a low-impedance structure is necessary. This type of inductor is suitable for use in both low and high power applications, such as in automotive audio systems, DC-DC converters, power amplifiers, and telecom equipments.

The working principle of the HKQ04023N7S-T is based on Faraday\'s law of induction. This law states that a voltage is induced in a conductor when it is exposed to a changing magnetic flux. In simple terms, this means that when a current passes through the primary of an inductor, a magnetic field is created. This magnetic field, in turn, induces a voltage in the secondary of the inductor, which produces an output voltage. The magnitude of the output voltage therefore depends on the amount of current passing through the primary of the inductor and the number of turns in the secondary.

In the case of the HKQ04023N7S-T, the fixed inductor has a fixed number of turns, and the magnetic field created will be proportional to the current passing through the inductor. This means that the output voltage of the inductor, and therefore the inductance, will remain constant regardless of the amount of current passing through it. The SRF value of the inductor is also unaffected by the amount of current passing through it.

The HKQ04023N7S-T has a wide range of applications due to its high power handling ability and low impedance characteristics. It has a wide range of inductance values and can be used in a variety of applications, such as in automotive audio systems, power amplifiers, DC-DC converters, and telecom equipment. The fixed inductor is also ideal for maintaining electrical isolation in circuits, and for providing low impedance paths for high current applications.
