Molding SMD Power Inductors LanTu Micro SMS0850-470MT designed for high density electronic applications
Molding SMD Power Inductors - SMS0850 Series
The SMS0850 Series by SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. offers ultra-high current SMD power inductors designed for demanding applications. These inductors feature a thin profile with low DC resistance and ultra-high current capabilities. Their magnetic shielding provides strong anti-electromagnetic interference, making them suitable for high-density installations. The integral construction ensures high reliability and excellent vibration resistance, while the composite structure minimizes buzz noise. Utilizing low-loss alloy powder die-casting, these inductors offer low impedance and small parasitic capacitance, contributing to high efficiency and reduced core eddy-current loss. They operate at frequencies up to 1-2MHz and have an absolute maximum voltage of 30VDC. The series is RoHS, Halogen Free, and REACH compliant.

Reminders for Using These Products
- Storage: Within 12 months, under conditions of 5~40C and 35~65% RH.
- Environment: Avoid use and storage in corrosive gas environments (salt, acid, alkali, etc.).
- Handling: Avoid direct contact with terminals by bare hands due to oils affecting solderability. Handle carefully to prevent damage.
- Terminal Bending: Do not excessively bend terminals 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; temperature difference between solder and chip should not exceed 150C.
- Soldering Corrections: Perform after mounting within specified conditions; overheating can cause issues.
- Thermal Design: Allow sufficient margin for self-heating when power is on.
- Non-Magnetic Shield Type: Careful layout is needed on the circuit board to avoid malfunctions due to magnetic interference.
