Molding SMD Power Inductors - SMS0630 Series
Product Overview
The SMS0630 Series from SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. are ultra-high current SMD power inductors designed for high-density installation. Featuring a thin profile with low DC resistance and ultra-high current capabilities, these magnetically shielded inductors offer strong anti-electromagnetic interference. Their integral construction ensures high reliability and excellent vibration resistance, while the composite structure minimizes buzz noise. Built with low-loss alloy powder for die-casting, they provide low impedance and small parasitic capacitance, leading 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 comply with RoHS, Halogen Free, and REACH standards.

Reminders for Using These Products
- Storage: Within 12 months. Conditions: 5~40C, 35-65% RH. Soldering of terminal electrodes may deteriorate if storage period elapses.
- Environment: Do not use or store in gas corrosive environments (salt, acid, alkali, etc.).
- Handling: Avoid direct contact with terminals due to hand oils affecting solderability. Handle carefully to prevent damage from dropping.
- Terminal Bending: Do not bend terminals with excessive stress to prevent wire fracture.
- Cleaning: Do not rinse coils. Contact SXN 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 Correction: Post-mounting soldering corrections must be within specified conditions. Overheating may cause short circuits, performance degradation, or reduced lifespan.
- Thermal Design: Account for self-heating when power is ON. Ensure sufficient thermal design margin.
- Non-Magnetic Shield Type: Careful coil layout is required on the circuit board to prevent malfunctions due to magnetic interference.
