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 by bare hands due to oil secretions. Handle carefully to prevent damage.
- Terminal Bending: Do not bend terminals with excessive stress to avoid wire fracture.
- Cleaning: Do not rinse coils; contact the manufacturer if cleaning is necessary.
- Magnetism: Do not expose to magnets or magnetic fields.
- Preheating: Ensure preheating before soldering, with a temperature difference not exceeding 150C between solder and chip temperature.
- 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: Careful layout is needed to avoid malfunctions due to magnetic interference.
