Metal Composite Power Inductors: High Performance for Next-Gen Power Electronics
As electronic devices become more compact, powerful, and energy-efficient, the demand for advanced magnetic components has intensified. Metal composite power inductors have emerged as a critical solution for meeting the performance, thermal, and size requirements of modern power management systems.
What Are Metal Composite Power Inductors?
Metal composite power inductors are passive magnetic components that use a metallic magnetic powder (typically iron-based) embedded in a resin or polymer binder to form the magnetic core. Unlike traditional wire-wound or ferrite-based inductors, metal composite inductors offer superior DC bias characteristics, lower core losses, and better thermal stability—making them ideal for high-frequency DC-DC converters.
Key Advantages Over Traditional Inductors
High Current Tolerance
Metal composite cores support higher saturation current compared to ferrites, minimizing inductance drop under load.
