LanTu Micro SMS0420 R33MT molding SMD power inductors with low impedance and high current capability
Product Overview
The SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. SMS0420 Series are ultra-high current SMD power inductors featuring a thin design with low DC resistance. These magnetically shielded inductors offer strong anti-electromagnetic interference, making them suitable for high-density installations. Their integral construction provides high reliability and excellent vibration resistance, while the composite structure ensures ultra-low buzz noise. Designed for high efficiency, these inductors utilize low-loss alloy powder die-casting for low impedance and small parasitic capacitance, reducing winding DC resistance and core eddy-current loss. They operate at frequencies up to 3MHz and have an absolute maximum voltage of 30VDC, complying with RoHS, Halogen Free, and REACH standards. Applications include PDA, notebook, desktop, and server applications, high current POL converters, battery-powered devices, and DC/DC converters in distributed power systems.
