Product Overview
SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. presents the SMS0518 Series Ultra-high current SMD power inductors. These thin-profile inductors feature low DC resistance and ultra-high current capabilities, making them suitable for high-density installations due to their magnetic shielding and strong anti-electromagnetic interference. The integral construction ensures high reliability and excellent vibration resistance, while the composite structure minimizes buzz noise. Designed for high efficiency, these inductors operate at frequencies up to 3MHz and are compliant with RoHS, Halogen Free, and REACH standards. They are ideal for applications such as PDA, notebooks, desktop and server applications, high current POL converters, battery-powered devices, and DC/DC converters in distributed power systems.
