Reminders for Using These Products:

• Storage period is within 12 months. Storage conditions: temperature 5~40C, humidity 35~65% RH or less.
• Do not use or store in gas corrosive environments (salt, acid, alkali, etc.).
• Avoid direct contact with terminals by bare hands to prevent solderability issues.
• Handle products carefully to prevent damage from dropping or improper removal.
• Do not bend terminals excessively to avoid wire fracture.
• Do not rinse coils; contact the manufacturer if cleaning is necessary.
• Do not expose products to magnets or magnetic fields.
• Preheat components before soldering; ensure temperature difference between solder and chip is within 150C.
• Soldering corrections after mounting should be within specified conditions to avoid short circuits, performance degradation, or reduced lifespan.
• Allow for sufficient thermal design margin due to self-heating when power is on.
• For non-magnetic shielded types, carefully consider coil layout on the PCB to prevent malfunctions due to magnetic interference.
