Reminders for Using These Products
- Storage: Within 12 months, under conditions of 5~40C and 35~65% RH. Solderability may deteriorate beyond this period.
- Environment: Avoid use and storage in corrosive environments (salt, acid, alkali, etc.).
- Handling: Avoid direct contact with terminals to prevent reduced solderability due to hand oils. Handle carefully to prevent damage from dropping.
- Terminal Bending: Do not excessively bend terminals to avoid wire fracture.
- Cleaning: Do not rinse coils. Contact the manufacturer if cleaning is necessary.
- Magnetic Fields: Do not expose products to magnets or magnetic fields.
- Preheating: Ensure preheating before soldering. The temperature difference between solder and chip should not exceed 150C.
- Soldering Corrections: Perform corrections within specified conditions to avoid short circuits, performance degradation, or reduced lifespan.
- Thermal Design: Account for self-heating when power is applied.
- Non-Magnetic Shield Type: Careful coil placement is required in PCB design to prevent malfunctions due to magnetic interference.
