Molding SMD Power Inductors - SMS0630 Series
Product Overview
The SMS0630 Series are ultra-high current SMD power inductors designed for high-density installations. These thin-profile inductors feature low DC resistance and ultra-high current handling capabilities, making them ideal for applications requiring efficient power conversion. Their magnetic shielding provides strong anti-electromagnetic interference, while the integral construction ensures high reliability and excellent vibration resistance. The composite structure minimizes buzz noise, and the low-loss alloy powder die-casting contributes to low impedance and small parasitic capacitance, resulting in high efficiency and reduced core eddy-current loss. These inductors are suitable for frequencies up to 3MHz and have an absolute maximum voltage of 30VDC. They are RoHS, Halogen Free, and REACH compliant.

Important Notes for Usage
- Storage period is within 12 months under conditions (5~40C, 35-65% RH).
- Avoid use and storage in corrosive gas environments (salt, acid, alkali, etc.).
- Do not touch terminals directly with bare hands to prevent soldering issues.
- Handle products carefully to avoid damage from dropping or improper removal.
- Do not bend terminals excessively to prevent wire fracture.
- Do not clean coils; contact the manufacturer if cleaning is necessary.
- Keep products away from magnets or magnetic fields.
- Preheat components before soldering; ensure the temperature difference between solder and chip does not exceed 150C.
- Soldering corrections after mounting must be within specified conditions to avoid damage.
- Allow sufficient thermal design margin for self-heating when power is on.
- For non-magnetic shielded types, careful coil layout is required to prevent malfunctions due to magnetic interference.
