Dual Winding Shielding Inductors SMD Coupled Inductor for DC-DC Converter

SMD Coupled inductor

SMD (Surface Mount Device) coupled inductors are inductors designed for surface mounting on printed circuit boards (PCBs) and feature multiple windings that are magnetically linked, allowing for energy transfer between the windings. They are commonly used in applications like power supplies, DC-DC converters, and filters.

A coupled inductor is one in which the connection of two coils or inductors can be accomplished by electromagnetic induction. Each time an alternating current flows through the primary coil, the coil creates a magnetic field connected to the secondary coil and induces a voltage within the coil. The phenomenon of induced voltage from one inductor to another is called mutual inductance.

Coupling inductors are designed for a variety of applications. These compact coupled inductors have high saturation currents. The module can be used as a coupling inductor in a non-isolated DC/DC converter topology, or as a transformer in a flyback converter. They can also be used as common mode inductors on power lines. 

APPLICATIONS:

As a transformer: SEPIC,flyback

As an inductor:buck,boost,coupled inductor

DC-DC converters

VRM inductor for CPU and DDR power supplies

Input and output filter chokes

Widely used in buck converter, laptop, displayer,

network communication equipment, and etc.
