Fixed inductors, such as the SPD127-153M, are devices used to create a range of energy storage values, otherwise known as inductance. They are the building blocks for many varied circuits, such as power supplies, radio frequency circuits, or those employed to control peak currents in switched mode power supplies.

Inductors work on the principle of induction, that is, when a current runs through a coil, this creates a magnetic field surrounding the coil that can create a force on a second component electrical or magnetic attached to it. The force is proportional to the rate of change of the current in the coil. The higher the current and the faster it changes, the greater is the induced force.

The SPD127-153M fixed inductor, like all other inductors, is designed to store energy. Its inductance is specifically designed in order to store a specific amount of energy ranging from 18 to 27 µH. It is a bobbin-wound, surface mount device, featuring an epoxy resin body to seal the core and windings for environmental protection. The inductor has a rated current of up to 8 A, and temperature range from -25°C to +85°C which provides excellent temperature stability and reliability characteristics.

It is suited for various applications such as mobile phone chargers, electric vehicles, LED lighting, and power supplies. It is particularly useful in switched mode power supplies as it connects the high frequency transformer in the power supply, conditioning the current and smoothing the rectifier outputs. This is particularly important during high end power and voltage conversion applications, where inductors are used to ensure the good flow of both the input and the output current.

The SPD127-153M has a pulse current range up to 25 A, which is useful for applications such as manual switching, automobiles, power converters, or boosted circuits. Its low profile design makes it a suitable choice for use in applications where there is limited installation space.

In a nutshell, the SPD127-153M fixed inductor is a useful component that is frequently used in all types of energy-saving electronic circuits. It is also a highly reliable, robust device that is suitable for a wide range of applications including power supplies, LED lighting and electric vehicles. With its small profile and high temperature range, the SPD127-153M is a versatile component that is well suited for a variety of applications.
