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 with a thin profile for low DC resistance and high current capacity. Featuring magnetic shielding for strong anti-electromagnetic interference, these inductors are ideal for high-density installations. Their integral construction ensures high reliability and excellent vibration resistance, while the composite structure minimizes buzz noise. Utilizing low-loss alloy powder die-casting, they achieve low impedance and small parasitic capacitance, leading to high efficiency and reduced core eddy-current loss. These inductors support frequencies up to 3MHz and are compliant with RoHS, Halogen Free, and REACH standards.

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 oils. Handle carefully to prevent damage.
- Terminal Bending: Do not excessively bend terminals to avoid wire fracture.
- Cleaning: Do not rinse coils; contact manufacturer if cleaning is necessary.
- Magnetism: Do not expose to magnets or magnetic fields.
- Preheating: Preheat before soldering; temperature difference between solder and chip should not exceed 150C.
- Soldering Corrections: Perform within specified conditions to avoid overheating, 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 malfunctions due to magnetic interference.
