LanTu Micro SMS1050 6R8MT thin design power inductors with low impedance and small parasitic capacitance
Molding SMD Power Inductors - SMS1050 Series
Product Overview
The SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. SMS1050 Series Ultra-high current SMD power inductors are designed for high-density installation applications requiring low DC resistance and ultra-high current capabilities. Featuring a thin, magnetically shielded design to combat electromagnetic interference, these inductors offer high reliability with excellent vibration resistance due to their 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 are suitable for frequencies up to 3MHz and have an absolute maximum voltage of 30VDC, complying with RoHS, Halogen Free, and REACH standards.

Reminders for Using These Products:
- Storage period is within 12 months under conditions (temperature: 5~40C, humidity: 35 to 65% RH or less).
- Do not use or store in gas corrosive environments (salt, acid, alkali, etc.).
- Avoid direct contact with terminals by bare hands due to oil secretions.
- Handle products carefully to prevent damage.
- Do not bend terminals excessively.
- Do not rinse coils; 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 to avoid overheating.
- Allow sufficient thermal design margin for self-heating when power is ON.
- For non-magnetic shield types, careful coil layout is needed to avoid malfunctions due to magnetic interference.
