Product Description
Molding SMD Power Inductors - SMS1360 Series
Product Overview
The SMS1360 Series by SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. offers ultra-high current SMD power inductors designed for demanding applications. These inductors feature a thin profile with low DC resistance and ultra-high current capabilities. Their magnetic shielding provides strong anti-electromagnetic interference, making them ideal for high-density installations. Constructed with an integral molding structure, they offer high reliability and excellent vibration resistance, coupled with ultra-low buzz noise due to their composite construction. Utilizing low-loss alloy powder die-casting, they achieve low impedance and small parasitic capacitance, contributing to high efficiency by reducing winding DC resistance and core eddy-current loss. These inductors support frequencies up to 3MHz and have an absolute maximum voltage of 30VDC, while being RoHS, Halogen Free, and REACH compliant.
Applications
Suitable for PDA, notebook, desktop, and server applications, high current POL converters, battery-powered devices, and DC/DC converters in distributed power systems.
