Reminders for Using These Products
- Storage: Within 12 months, under conditions (5~40C, 35~65% RH or less).
- Environment: Avoid gas corrosive environments (salt, acid, alkali, etc.).
- Handling: Avoid direct contact with terminals due to hand oils. Handle carefully to prevent damage.
- Terminal Bending: Do not bend terminals excessively to prevent wire fracture.
- Cleaning: Do not rinse coils. Contact manufacturer if cleaning is necessary.
- Magnetic Fields: Do not expose to magnets or magnetic fields.
- Preheating: Preheat components before soldering. Temperature difference between solder and chip should not exceed 150C.
- Soldering Corrections: Perform after mounting within specified conditions. Overheating may cause issues.
- Thermal Design: Account for self-heating when power is ON.
- Layout: For non-magnetic shielded types, careful coil placement is needed to avoid malfunction due to magnetic interference.
