Fixed inductors are a type of electrical component that store energy in the form of a magnetic field. They are also known as chokes, coils, inductors or reactors. These components are used in many common electronics applications such as power supplies, signal filtering and noise reduction, and tank circuits. One of the common types of these devices is the ASPI-M3015-3R3M-T inductor.

Components and Construction

The ASPI-M3015-3R3M-T is a surface mount fixed inductor, featuring a low profile design. The device is made up of two main components: a magnetic core, and an insulated copper wire winding. The core is made of MnZn ferrite material and serves as the primary pathway for the magnetic field. The winding is composed of an insulated copper wire and is encased in a plastic casing. This provides protection and insulation to the inductor windings. This device has a maximum DC current rating of 3.3 A and an inductance of 15 uH.

Application Field

The ASPI-M3015-3R3M-T is widely used in a variety of consumer electronics applications. The low profile and the 3.3A current rating make it suitable for power supplies and DC-DC converters. In these applications, the inductor serves to filter out noise and improve efficiency. It can also be used with switching regulators to help reduce voltage ripple and achieve stable power supply outputs. The ASPI-M3015-3R3M-T is also used in EMI/RFI suppression circuits and in radio frequency applications.

Working Principle

A fixed inductor operates by storing electrical energy in the magnetic field created by the winding current. When an AC voltage is applied across the inductor, an alternating current is generated. This current generates a magnetic field which, in turn, opposes the current. This opposition creates an inductive reactance that restricts the amount of current that can flow through the inductor. In other words, the inductor blocks high frequency signals, while allowing low frequency signals to pass through.

The magnetic field generated by the inductor also serves to store the energy. The stored energy is then released when the current is removed and the magnetic field dissipates. This energy is usually returned to the power supply and gives the inductor its characteristic voltage regulation capability. This applied voltage is known as the "back electromotive force" (EMF).

Conclusion

The ASPI-M3015-3R3M-T is a low profile fixed inductor that is used in a wide variety of consumer electronics applications. It is commonly used in DC-DC converters, EMI/RFI suppression, and radio frequency applications. The inductor works by creating a magnetic field that stores energy. This energy is released when the current is removed, and is used to regulate the applied voltage. This makes the inductor a useful component for applications requiring high efficiency and noise reduction.
