Compact molding SMD power inductors featuring LanTu Micro SMS0850-330MT with ultra high current capacity and low DC resistance
Molding SMD Power Inductors - SMS0850 Series
Product Overview
The SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. SMS0850 Series Ultra-high current SMD power inductors are designed for high-density installation with excellent anti-electromagnetic interference due to their magnetic shielding. Featuring a thin design with low DC resistance and ultra-high current capabilities, these inductors offer high reliability and superior vibration resistance through an integral construction. The composite structure minimizes buzz noise, while the low-loss alloy powder die-casting ensures low impedance and small parasitic capacitance, leading to high efficiency and reduced core eddy-current loss. They operate at frequencies up to 1-2MHz and are compliant 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 period is within 12 months. Storage conditions: temperature 5~40C, humidity 35~65% RH or less.
- Do not use or store in locations with gas corrosion (salt, acid, alkali, etc.).
- Avoid direct contact with terminals by bare hands due to oil secretions.
- Handle products carefully to prevent damage from dropping or inappropriate removal.
- Do not bend terminals with excessive stress to prevent wire fracture.
- Do not rinse coils by yourself; contact the manufacturer if cleaning is necessary.
- Do not expose products to magnets or magnetic fields.
- Preheat components before soldering. Temperature difference between solder and chip should not exceed 150C.
- Soldering corrections after mounting should be within specified conditions. Overheating may cause short circuits, performance degradation, or reduced lifespan.
- Allow for sufficient thermal design margin due to self-heating when power is on.
- For non-magnetic shield types, careful layout is required to prevent malfunctions due to magnetic interference.
