Reminders for Using These Products:
- Storage: Within 12 months. Conditions: 5~40C, 35-65% RH. Exceeding storage time may degrade terminal solderability.
- Environment: Do not use or store in corrosive gas environments (salt, acid, alkali, etc.).
- Handling: Avoid direct contact with terminals to prevent soldering issues due to hand oils. Handle carefully to prevent damage from dropping.
- Terminal Bending: Do not bend terminals excessively to avoid wire fracture.
- Cleaning: Do not clean coils independently; contact the manufacturer if cleaning is necessary.
- Magnetic Fields: Do not expose products to magnets or magnetic fields.
- Preheating: Preheat components before soldering. Ensure the temperature difference between solder and chip does not exceed 150C.
- Soldering Corrections: Perform soldering corrections within specified conditions. Overheating may cause short circuits, performance degradation, or reduced lifespan.
- Thermal Design: Account for self-heating when power is applied. Ensure sufficient thermal design margin.
- Non-Shielded Type Layout: For non-magnetic shielded types, carefully consider coil placement on the PCB to prevent malfunctions due to magnetic interference.
