Product Overview
The SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. SMS0850 Series Ultra-high current SMD power inductors are designed for high-density installation with excellent anti-electromagnetic interference due to their magnetic shielding. These thin-profile inductors feature low DC resistance and ultra-high current handling capabilities, utilizing an integral construction for high reliability and vibration resistance. 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 2MHz with an absolute maximum voltage of 30VDC, these RoHS, Halogen Free, and REACH compliant inductors are ideal for PDA, notebook, desktop, server applications, high current POL converters, battery-powered devices, and DC/DC converters in distributed power systems.
