Refer to the provided graph for recommended reflow conditions. Adjustments may be necessary based on specific user environments and equipment.
Reminders for Using These Products:
- Storage: Within 12 months, under conditions of 5~40C and 35~65% RH.
- Environment: Avoid use or storage in corrosive gas environments (salt, acid, alkali).
- Handling: Avoid direct contact with terminals with bare hands to prevent soldering issues. 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.
- Magnetism: Keep away from magnets or magnetic fields.
- Preheating: Preheat components before soldering; the temperature difference between solder and chip should not exceed 150C.
- Soldering Correction: Post-mounting soldering corrections must adhere to specifications; overheating can cause issues.
- Thermal Design: Account for self-heating when power is applied.
- Layout (Non-magnetic shield type): Careful coil placement is required to prevent malfunctions due to magnetic interference.
