The SMS1040 Series by SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. offers ultra-high current SMD power inductors with a thin design, low DC resistance, and superior current handling capabilities. Featuring magnetic shielding for strong anti-electromagnetic interference and an integral construction for high reliability and vibration resistance, these inductors are ideal for high-density installations. Their composite structure minimizes buzz noise, while the low-loss alloy powder die-casting ensures low impedance and small parasitic capacitance, contributing to high efficiency. Operating up to 3MHz with an absolute maximum voltage of 30VDC, these RoHS, Halogen Free, and REACH compliant inductors are suitable for a wide range of applications including PDAs, notebooks, servers, high current POL converters, battery-powered devices, and DC/DC converters in distributed power systems.
