The SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. SMS0850 Series are ultra-high current SMD power inductors designed for high-density installation. These magnetically shielded inductors offer strong anti-electromagnetic interference capabilities, low DC resistance, and ultra-high current thin design. Featuring an integral construction for high reliability and vibration resistance, they also provide ultra-low buzz noise due to their composite structure. Manufactured using low-loss alloy powder die-casting, they exhibit low impedance and small parasitic capacitance, contributing to high efficiency by reducing eddy-current loss. These inductors operate at frequencies up to 1-2MHz and have an absolute maximum voltage of 30VDC. They are RoHS, Halogen Free, and REACH compliant.
