LanTu Micro SMS0630 470MT ultra high current molding power inductor with low impedance and low noise

Product Overview

The SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. SMS0630 Series are ultra-high current SMD power inductors designed for high-density installation. These magnetically shielded inductors offer strong anti-electromagnetic interference, low DC resistance, and ultra-high current capabilities in a thin profile. Featuring an integral construction for high reliability and vibration resistance, they also provide ultra-low buzz noise due to their composite structure. Die-casting with low-loss alloy powder results in low impedance and small parasitic capacitance, contributing to high efficiency by reducing winding DC resistance and core eddy-current loss. These inductors are suitable for frequencies up to 3MHz and have an absolute maximum voltage of 30VDC. They are compliant with RoHS, Halogen Free, and REACH standards.

Reminders for Using These Products

• Storage: Within 12 months, at 5~40C and 35-65% RH.
• Environment: Avoid gas corrosive environments (salt, acid, alkali).
• Handling: Avoid direct contact with terminals to prevent soldering issues. Handle with care to prevent damage.
• Terminal Bending: Do not excessively bend terminals to avoid wire fracture.
• Cleaning: Do not rinse coils; contact the manufacturer if cleaning is required.
• Magnetism: Keep away from magnets or magnetic fields.
• Preheating: Preheat components before soldering, with a temperature difference not exceeding 150C between solder and chip temperature.
• Soldering Corrections: Perform within specified conditions to avoid short circuits, performance degradation, or reduced lifespan.
• Thermal Design: Account for self-heating when power is on.
• Layout: For non-magnetic shield types, careful coil layout is needed to prevent malfunction due to magnetic interference.
