SMD Power Inductor LanTu Micro SNR3015-3R3MT Magnetic Resin Shielded for Durable Power Applications
Product Overview
The SNR3015 Series from SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. is an automatically assembled, magnetic resin shielded SMD power inductor. Designed for high performance and reliability, these inductors significantly reduce buzz noise to ultra-low levels due to their magnetic-resin shielded construction. They offer large current handling capabilities with low DC resistance, a closed magnetic circuit design for reduced leakage flux and strong EMI resistance, and metallization on the ferrite core for excellent shock resistance and durability. These space-saving and power-efficient components are suitable for a wide range of applications including LED backlights, flat-screen TVs, notebooks, servers, automotive systems, and DC-DC converters.

Recommended Reflow Soldering Curve
Refer to the provided graph for recommended reflow conditions. Adjustments may be necessary based on user's specific equipment and process.
Usage Reminders
- Storage period: within 12 months under conditions (5~40C, 35~65% RH).
- Avoid use and storage in corrosive environments (salt, acid, alkali).
- Do not touch electrodes directly with bare hands.
- Handle products carefully to prevent damage.
- Do not bend terminals excessively.
- Do not rinse coils; contact the manufacturer if cleaning is required.
- Keep away from 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 performance degradation.
- Consider self-heating when designing for thermal management.
