Fixed inductors, also known as chokes or coils, are electronic components that have an electromagnetic field, typically made of a coil of insulated wire wound around a core, and the core is usually a ferrite material. Most fixed inductors used for switching applications require very low series inductance and saturation current, such as the SPM4015T-3R3M-LR.

The SPM4015T-3R3M-LR is a self-leaded, surface-mount inductor which is designed for fast switching applications. It has a low profile of less than 2.5mm, which makes it ideal for a variety of applications such as power supplies, electronic ballasts, LCD display panels, and intelligent power modules. The SPM4015T-3R3M-LR features extreme current features with low series inductance and high saturation current. It also has excellent self-heating characteristics, making it a cost-effective choice for many applications.

The SPM4015T-3R3M-LR is a surface-mount component which consists of a copper wire wound around an insulating core. The copper wire is insulated by a special polyimide tape, and the core is made of a special ferrite material which helps the inductor achieve its low inductance. The core component is designed to help the inductor reach a low AC resistance, ensuring that it can be used for fast switching applications with low power loss.

The working principle of the SPM4015T-3R3M-LR is that it stores energy in the form of a magnetic field, which is created by a current flowing through the inductor. As the current increases, the inductance increases and so does the energy stored in the magnetic field. When the current is removed, the energy stored is released as a voltage across the inductor.

The SPM4015T-3R3M-LR is able to achieve its low series inductance and high saturation current thanks to its wide copper coil windings and the use of a special core material. The core material helps the inductor reach a low AC resistance, allowing for maximum power transfer and efficiency in switching applications. The wide copper windings also help to reduce any unwanted EMF radiation, ensuring that the inductor is able to operate at optimal performance.

The SPM4015T-3R3M-LR is an ideal choice for a range of switching applications, thanks to its low profile of less than 2.5mm. Its wide copper windings and special core material help to reduce EMF radiation, allowing it to achieve high power transfer and efficiency. It also boasts excellent self-heating characteristics, making it a cost-effective choice for many applications.
