| Model Number | SMS1050-1R5MT |
The SMS1050 Series from SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. are ultra-high current, thin design SMD power inductors featuring magnetic shielding for strong anti-electromagnetic interference, making them suitable for high-density installations. These high-reliability inductors utilize an integral construction for excellent vibration resistance and a composite structure for ultra-low buzz noise. They are manufactured using low-loss alloy powder die-casting, resulting in low impedance, small parasitic capacitance, high efficiency, and reduced winding DC resistance and core eddy-current loss. Operating at frequencies up to 3MHz with a maximum insulation voltage of 30VDC, these inductors comply with RoHS, Halogen Free, and REACH standards. They are ideal for applications such as PDA, notebook, desktop, and server applications, high current POL converters, battery-powered devices, and DC/DC converters in distributed power systems.
