Molding SMD Power Inductors - SMS0518 Series
Product Overview
The SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. SMS0518 Series offers ultra-high current SMD power inductors designed for high-density installations. These inductors feature a thin profile with low DC resistance and ultra-high current capabilities. Their magnetic shielding provides strong anti-electromagnetic interference, making them suitable for demanding applications. The integral construction ensures high reliability and excellent vibration resistance, while the composite structure minimizes buzz noise. Utilizing low-loss alloy powder die-casting, these inductors achieve low impedance and small parasitic capacitance, contributing to high efficiency and reduced core eddy-current loss. They are capable of operating at frequencies up to 3MHz and have an absolute maximum voltage of 30VDC. The series is RoHS, Halogen Free, and REACH compliant.

Reminders for Using These Products
- Storage: Within 12 months, under 5~40C and 35~65% RH.
- Environment: Avoid gas corrosive environments (salt, acid, alkali).
- Handling: Avoid direct contact with terminals due to oil secretions. Handle carefully to prevent damage. Do not bend terminals excessively.
- Cleaning: Do not rinse coils; contact the manufacturer if cleaning is necessary.
- Magnetism: Do not expose to magnets or magnetic fields.
- Preheating: Preheat components before soldering; temperature difference between solder and chip should not exceed 150C.
- Soldering Corrections: Perform within specified conditions to avoid short circuits, performance degradation, or reduced lifespan.
- Thermal Design: Allow sufficient margin for self-heating when power is ON.
- Layout: For non-magnetic shield types, careful coil placement on the PCB is required to prevent malfunction due to magnetic interference.
