Fixed Inductors

Fixed inductors are passive electronic components used in electrical circuits to store energy in magnetic fields. The induction of an inductor is defined as the ratio of the magnetic flux to the current, L = Φ / I. Fixed inductors are typically wound on a ferrite core and range in size from tiny surface-mount devices (SMD) to large through-hole components.

AIMC-0402HQ-7N5J-T application field and working principle

The AIMC-0402HQ-7N5J-T is a surface mount ferrite core fixed inductor, capable of storing electrical energy in a magnetic field. It is designed for use in switching power supplies, filtering, cellular phones, DC-DC converters, cellular base stations, etc. It is rated at 7.5nH with a maximum DC current of 6.2A and a saturation current of 8.6A.

Fixed inductors are commonly used in power supply circuits to filter the input current and reduce ripple. This inductor is rated for high current loads and is suitable for high frequency applications such as DC-DC switching converters, PLLs, embedded system, and AC/DC power supplies.

The AIMC-0402HQ-7N5J-T operates by using a wire wound around the ferrite core, where the changes of current in the wire create a magnetic field. This magnetic field in turn induces a voltage in the same wire, and thus an inductor acts as a resistor to AC current. This is known as Faraday’s Law of Electromagnetic Induction. The resulting frequency response of the inductor is determined by the inductance and reactance of the coil, and the size and shape of the ferrite core.

The AIMC-0402HQ-7N5J-T is designed to handle high current, high frequency applications at a low cost, which makes it a great value component for many applications.
