Molding SMD Power Inductors - SMS0630 Series
Product Overview
The SMS0630 Series Ultra-high current SMD power inductors are designed for high-density installation and demanding applications. Featuring a thin profile with low DC resistance and ultra-high current capability, these magnetically shielded inductors offer strong anti-electromagnetic interference. Their integral construction provides high reliability and excellent vibration resistance, while the composite structure ensures ultra-low buzz noise. Manufactured using low-loss alloy powder die-casting, they exhibit low impedance and small parasitic capacitance, leading to high efficiency and reduced core eddy-current loss. These inductors support frequencies up to 3MHz and have an absolute maximum voltage of 30VDC, complying with RoHS, Halogen Free, and REACH standards.
Applications
These inductors are suitable for PDA, notebook, desktop, and server applications, high current POL converters, battery-powered devices, and DC/DC converters in distributed power systems.

Reminders for Using These Products
- Storage: Within 12 months, under conditions of 5~40C and 35~65% RH. Terminal solderability may deteriorate beyond this period.
- Environment: Avoid use and storage in corrosive gas environments (salt, acid, alkali, etc.).
- Handling: Avoid direct contact with terminals by bare hands due to oil secretions that may inhibit soldering. Handle products carefully to prevent damage.
- Terminal Bending: Do not bend terminals with excessive stress to prevent wire fracture.
- Cleaning: Do not rinse coils. Contact the manufacturer if cleaning is necessary.
- Magnetism: Do not expose products to magnets or magnetic fields.
- Preheating: Preheat components before soldering. The temperature difference between solder and chip should not exceed 150C.
- Soldering Corrections: Post-mounting soldering corrections should 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: Carefully lay out coils on the circuit board to prevent malfunctions due to magnetic interference.
