Fixed Inductors

Fixed inductors, also known as chokes, are electrical components that have the purpose of creating a magnetic field. Inductors are typically used in many different types of electrical systems, from small consumer electronics to large industrial machines. The purpose of inductors is to store and release energy, and the particular type of inductor used determines the amount of energy that can be stored. This article will discuss the application field and working principle of the ASPI-0418S-3R9N-T3 inductor.

Application Field

The ASPI-0418S-3R9N-T3 inductor is a non-shielded, ferrite core, power inductor designed for high-current and low-profile applications. Its small size and high current capability makes it suitable for use in a wide variety of electronic devices, including power supplies, digital cameras, audio amplifiers, and high performance processors. It is also commonly used to filter power supply lines and reduce voltage ripple. It is designed to be used in conjunction with surface mount components to provide a high-performance solution for high power applications.

Working Principle

The working principle of a fixed inductor such as the ASPI-0418S-3R9N-T3 is based on the principles of inductance, the ability of a coil to store and release energy. As current passes through the inductor, an electromagnetic field is created around the wire. This creates an electrical resistance that opposes any change in the current. This property of inductors is known as self-inductance and can be mathematically described as L= Φ/I, where L is the inductance, Φ is the total number of turns on the coil, and I is the current.

The ASPI-0418S-3R9N-T3 has an inductance of 3.9nH, which is the amount of energy the inductor can store when a 1A current passes through it. This inductor is also rated for operation up to 1MHz, which is quite a high frequency range for an inductor of this size. At higher frequencies the inductor performs better by reducing voltage ripple and increasing power transfer efficiency.

The ASPI-0418S-3R9N-T3 may also be used in other applications where an inductor is required to filter the power supply lines. It is designed to have a higher current capacity than other inductors, so it is able to handle larger power supply lines without bogging down. This makes it an ideal choice for applications such as desktop PCs, gaming consoles, and other power-hungry electronic devices.

In conclusion, the ASPI-0418S-3R9N-T3 is a small, high-current, non-shielded, ferrite core inductor that is suitable for a wide variety of electronic devices. Its small size and impressive current capacity makes it a perfect choice for high-powered applications. Additionally, its high frequency range allows it to reduce voltage ripple and increase power transfer efficiency. As a result, the ASPI-0418S-3R9N-T3 is an excellent choice for any application requiring a fixed inductor.
