Product Overview
The SNR5020 Series is an automatic assembly, magnetic resin shielded SMD power inductor designed to significantly reduce buzz noise to ultra-low levels. It features a closed magnetic circuit design for reduced leakage flux and strong EMI resistance, along with metallization on the ferrite core for excellent shock resistance and durability. This series offers large current handling capabilities with low DC resistance, making it space-saving and power-efficient. It is widely used in applications such as LED backlights, flat-screen TVs, notebooks, servers, graphics cards, automotive systems, and DC-DC converters.

Reminders for Using These Products
- Storage period is within 12 months under conditions (5~40C, 35~65% RH).
- Avoid use and storage in corrosive gas environments.
- 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.
- 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 performance degradation.
- Allow for sufficient thermal design due to self-heating when powered on.
