Fixed inductors are electronic components that provide inductance and maintain a fixed level of inductance. Generally speaking, the value of the inductance does not change with different input signals or changing load conditions. As shown in the figure below, fixed inductors are composed of metal windings, a ferrite core, and an outer shell. The ferrite core provides the inductance, the metal winding is used to provide the electrical connection, and the shell is used to protect the inductor.

The ASPI-3012S-270M-T is a fixed inductor with inductance of 27 microhenries, and is designed to withstand operating temperatures up to 155 Celsius. This wide temperature range makes this inductor suitable for use in high-temperature environments. Additionally, this inductor is constructed of aluminum metal and carries a maximum rated current of 1 amp, making it an ideal choice for applications which require high current handling capability.
The ASPI-3012S-270M-T is usually used as an output filter for switching power supplies, as the wide temperature range and the high current rating make it suitable for high-current filtering applications. Additionally, it is used in DC-DC converters, resonant circuits, voltage converters, voltage regulators, and as LC filters in high-frequency applications. In these applications, the inductor provides filtering and suppression of unwanted high-frequency signals.

The working principle of a fixed inductor is based on Faraday’s Law of Induction. According to this principle, a changing magnetic field will induce an electric current in a nearby conductor. In the ASPI-3012S-270M-T, the changing input signals generate a changing magnetic field, inducing electric current in the metal windings. This process of induction creates the inductive reactance which prevents the AC signals from passing through the inductor.
The amount of inductive reactance is determined by the inductance value, so the inductance of the inductor can be varied by changing the number of turns in the winding, or by changing the size of the ferrite core. Different inductor models have different inductance values, so different models will have different amounts of inductive reactance.

The ASPI-3012S-270M-T is a powerful and reliable inductor, providing excellent performance in high-temperature and heavy-duty applications. Its wide temperature range and high current rating make it suitable for a variety of power supply filtering and conversion applications. Moreover, its inductive reactance is determined by the inductance value, the number of turns in the winding, and the size of the ferrite core, providing an effective filter for suppressing unwanted frequencies.
