LanTu Micro SMS0850 6R8MT molding power inductor with low impedance and ultra high current capability
Product Overview
The SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. SMS0850 Series is an ultra-high current SMD power inductor designed for high-density installations. It features a thin profile with low DC resistance and ultra-high current capability, enhanced by magnetic shielding for strong anti-electromagnetic interference. The integral construction provides high reliability and excellent vibration resistance, while the composite structure minimizes buzz noise. Utilizing low-loss alloy powder die-casting, these inductors offer low impedance, small parasitic capacitance, and high efficiency with reduced core eddy-current loss. They are suitable for applications requiring frequencies up to 1-2MHz and have an absolute maximum voltage of 30VDC. The series is RoHS, Halogen Free, and REACH compliant.
