Product Description
Product Overview
The LANTU SNR5030 Series are automatic assembly, magnetic resin shielded SMD power inductors designed for high-current, low-DCR applications. These inductors feature a closed magnetic circuit design that minimizes leakage flux and electromagnetic interference (EMI), while the magnetic-resin shielding significantly reduces buzz noise to ultra-low levels. Their compact size and power-saving capabilities make them ideal for a wide range of electronic devices, including LED backlights, flat-screen TVs, notebooks, servers, automotive products, and DC-DC converters. They are constructed with metallization on the ferrite core for excellent shock resistance and durability.

Usage Reminders
- Storage period is within 12 months. Storage conditions: temperature 5~40C, humidity 35~65% RH or less.
- Do not use or store in environments with gas corrosion (salt, acid, alkali, etc.).
- Avoid direct contact with terminals by bare hands to prevent reduced solderability due to oil secretions.
- Handle products carefully to prevent damage from dropping or improper removal.
- Do not bend terminals with excessive stress to avoid wire fracture.
- Do not rinse coils. Contact LANTU if cleaning is necessary.
- Do not expose products to magnets or magnetic fields.
- Preheat components before soldering. The temperature difference between solder and chip temperature should not exceed 150C.
- Soldering corrections after mounting should be within specified conditions. Overheating may cause short circuits, performance degradation, or lifespan reduction.
- Allow sufficient thermal design margin as self-heating occurs when power is ON.
