Product Overview
The SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. SMS0850 Series is an ultra-high current SMD power inductor designed for high-density installation. It features a thin profile with low DC resistance and ultra-high current handling capabilities. The magnetic shielding provides strong anti-electromagnetic interference, while the integral construction ensures high reliability and excellent vibration resistance. Its composite structure results in ultra-low buzz noise and low loss alloy powder die-casting contributes to low impedance and small parasitic capacitance, leading to high efficiency by reducing winding DC resistance and core eddy-current loss. These inductors operate at frequencies up to 1-2MHz and are RoHS, Halogen Free, and REACH compliant.
