Product Description
Product Overview
The SNR5020 Series are magnetic resin shielded SMD power inductors from SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. These automatic assembly compatible inductors are designed to 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 enhanced EMI resistance, and metallization on the ferrite core for excellent shock resistance and durability. Their compact size saves PCB real estate and reduces power consumption. These inductors are widely used in applications such as LED backlights, flat-screen TVs, set-top boxes, notebooks, desktop computers, servers, graphic cards, portable gaming devices, personal navigation systems, multimedia devices, automotive systems, telecommunication base stations, and DC-DC converters. They comply with RoHS, Halogen Free, and REACH standards.

Reminders for Using These Products
- Storage: Within 12 months, temperature 5~40C, humidity 35~65% RH or less.
- Environment: Avoid gas corrosive environments (salt, acid, alkali, etc.).
- Handling: Avoid direct contact with terminals by bare hands due to oil secretions. Handle carefully to prevent damage from dropping or improper removal. Avoid excessive bending of terminals.
- Cleaning: Do not rinse coils; contact the manufacturer if cleaning is necessary.
- Magnetic Fields: Do not expose 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 issues.
- Thermal Design: Allow sufficient margin for self-heating when power is ON.
- Non-Magnetic Shield Type: Consider coil layout in board design to prevent malfunction due to magnetic interference (Note: SNR5020 is magnetic shielded).
