Product Description
Molding SMD Power Inductors - SMS1040 Series
Product Overview
The SMS1040 Series by SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. are ultra-high current, thin-profile SMD power inductors designed for high-density installations. Featuring magnetic shielding for strong anti-electromagnetic interference, these inductors offer high reliability with an integral construction for excellent vibration resistance. Their composite structure minimizes buzz noise, while the use of low-loss alloy powder results in low impedance, small parasitic capacitance, and high efficiency. Suitable for applications requiring frequencies up to 3MHz and an absolute maximum voltage of 30VDC, they are RoHS, Halogen Free, and REACH compliant.

Important Notes for Using These Products
- Storage Period: Within 12 months. Storage conditions: 5~40C, 35-65% RH.
- Environment: Avoid use and storage in gas corrosive environments (salt, acid, alkali, etc.).
- Handling: Avoid touching terminals directly with bare hands. Handle products carefully to prevent damage.
- Terminals: Do not bend terminals with excessive stress.
- Cleaning: Do not rinse coils; contact the manufacturer if cleaning is necessary.
- Magnetic Fields: Do not expose products to magnets or magnetic fields.
- Preheating: Ensure preheating before soldering. Temperature difference between solder and chip should not exceed 150C.
- Soldering Corrections: Perform within specified conditions. Overheating may cause short circuits, performance degradation, or reduced lifespan.
- Thermal Design: Allow sufficient margin for self-heating when power is on.
- Non-Magnetic Shield Type: Careful layout is required to prevent malfunctions due to magnetic interference.
