Fixed inductors, also called fixed chokes, are types of electronic components which are designed to create an inductive load, store magnetic energy and oppose changes to current flow in electric circuits. The AIMC-0402HQ-2N7C-T is a type of fixed inductor which is designed for use in general-purpose, surface-mount applications.

Generally, these inductors are characterized by a fixed inductance value and tolerate a certain amount of DC bias, which makes them ideal for use in filtering, coupling, and decoupling applications. Specifically, the AIMC-0402HQ-2N7C-T can be used in power supplies, DC–DC converters, linear regulators, and switching converters.

The AIMC-0402HQ-2N7C-T is an inductor comprised of a sealed and molded 130-micrometer ferrite core with a 2” (50 mm) diameter and a 13 nH inductance value. Sunlord manufactures the part with a gold-plated, tin-plated copper terminal. It has an operating temperature range of -40 °C to +85 °C and an insulation resistance of 500 VDC or greater. The part’s tolerance rating is specified at 5% and its self-resonant frequency is 6 MHz.

The AIMC-0402HQ-2N7C-T uses a ferrite core, which is a magnetic material composed of iron oxide ceramic composed of a combination of iron, strontium, barium, and/or other elements. The core’s permeability attributes allow it to present a high impedance to the inductor’s DC bias, which, in turn, allows the AIMC-0402HQ-2N7C-T to control and maintain stable current flow in the electric circuit.

The AIMC-0402HQ-2N7C-T uses a powdered iron ferrite core because it offers numerous advantages. Powdered iron ferrite cores can be used in lower-frequency applications due to their low frequency saturation properties. Additionally, these cores are not affected by magnetic fields, making them especially useful in high interference environments. Furthermore, the core material’s thermal coefficient of resistance is very low, making it ideal for applications requiring temperature-stable performance.

The working principle of the AIMC-0402HQ-2N7C-T is based on Faraday’s Law of Induction. According to Faraday’s Law, when the current in a coil changes, it induces a voltage across the coil. Conversely, when current flows in a coil, it induces a magnetic field around the coil, which can be used to store energy in the form of a magnetic field. This mechanism is the basic principle behind the AIMC-0402HQ-2N7C-T’s operation.

The AIMC-0402HQ-2N7C-T is an effective and reliable fixed inductor due to its low DC resistance and high saturation currents. It is also capable of handling high DC currents as well as high AC frequencies, with good impedance characteristics. This makes it an ideal inductor for use in surface-mount applications such as power systems, portable electronics, and automotive applications.

In conclusion, the AIMC-0402HQ-2N7C-T fixed inductor is designed for general-purpose applications and is based on Faraday’s Law of Induction. Its powdered iron ferrite core allows it to present a high impedance to the inductor’s DC bias, allowing for stable and reliable current flow in the electric circuit. The part is capable of handling high DC currents as well as high AC frequencies, making it suitable for use in power systems, portable electronics, and automotive applications.
