Reminders for Using These Products
- Storage: Within 12 months, under conditions of 5~40C and 35-65% RH.
- Environment: Avoid use and storage in corrosive gas environments (salt, acid, alkali, etc.).
- Handling: Avoid direct contact with terminals due to hand oils; handle with care to prevent damage.
- Bending: Do not excessively bend terminals to avoid wire fracture.
- Cleaning: Do not rinse coils; contact the manufacturer if cleaning is necessary.
- Magnetic Fields: Keep away from magnets or objects with magnetic force.
- Preheating: Preheat components before soldering; temperature difference between solder and chip should not exceed 150C.
- Soldering Corrections: Perform after mounting within specified conditions to avoid overheating.
- Self-heating: Account for self-heating in thermal design.
- Non-magnetic Shielded Type: Careful layout is needed to prevent malfunction due to magnetic interference.
