Product Overview
The SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. SMS0650 Series are ultra-high current, thin-profile SMD power inductors designed for high-density installations. Featuring magnetic shielding for strong anti-electromagnetic interference, these inductors offer high reliability with an integral construction for excellent vibration resistance. Their composite structure minimizes buzz noise, while the low-loss alloy powder die-casting ensures low impedance and small parasitic capacitance. These inductors achieve high efficiency with low DC resistance and low core eddy-current loss, operating at frequencies up to 3MHz with a maximum insulation voltage of 30VDC. They are RoHS, Halogen Free, and REACH compliant.
Applications include: PDA, notebook, desktop, server applications, high current POL converters, battery-powered devices, and DC/DC converters in distributed power systems.
