Fixed Inductors

A fixed inductor designates the inductor that does not change its inductance (L) value regardless of current or frequency. Fixed inductors are one of the passive component known as electrical components that are used to assemble and construct electrical systems. The fixed inductor in particular interacts with a electrical current to produce a magnetic field that indroduces energy to the circuit. A fixed inductor can either be a small part of a system or it can be an essential part of a particular system\'s foundations.

SPM4020T-R47M-CA Application Field and Working Principle

The SPM4020T-R47M-CA fixed inductor is a surface mount component with an inductance of 4.7 mH. This fixed inductor has a wide variety of uses and presents itself to be a great solution for the implementations of various electronics such as power converters, and power supplies. It is specifically designed with small packages of 0402 format, low profile allowing it to fit into various types of application fields. The SPM4020T-R47M-CA fixed inductor is constructed with core made of high-frequency magnetic materials and insulation materials which can reach up to +105°C. The flat characteristics of this fixed inductor enable it to reach up to 30 Amps as its DC current rating.

The SPM4020T-R47M-CA fixed inductor is ideal for switching applications which instruments steady current production by reducing voltage drop. The inductance of this inductor is stable and will provide lower amounts of power dissipation when compared to other inductors. As mentioned, this inductor is designed with a small form factor; however, it is tolerant to high current, thus allowing it to produce the necessary stored energy for its applications. It is essential to note that this fixed inductor can range up to +105°C and therefore can be suitable for extended temperature application and able to dissipate heat more efficiently.

In terms of its working principle, the SPM4020T-R47M-CA fixed inductor operates similarly to other inductors. When inducing electric current through its winding electricty, a magnetic field will be created and is related to the magnetic flux. This flux paths circulate to generate the necessary inducted SELF-inductor voltage. In summary, this fixed inductor plays an important role in circuit design that it not only provides lower impedance but it also gives excellent inductance to its circuits.
