Recommended Lead-free Wave Soldering (DIP-Type)
The recommended wave soldering is a reference. Users should adjust and confirm soldering conditions according to their environment/equipment.
Soldering Iron (Rework)
- Use soldering iron for hand soldering, times not exceeding 3 times, temperature not exceeding 350 degrees.
- Avoid contacting the inductor itself during soldering.
- Soldering inductors by soldering iron is not recommended.
Reminders for Using These Products
- Storage: Within 12 months. Conditions: 5~40C, 35~65% RH or less. Soldering of terminal electrodes may deteriorate if storage period elapses.
- Environment: Do not use or store in gas corrosive environments (salt, acid, alkali, etc.).
- Handling: Avoid direct contact with terminals with bare hands due to oil secretions. Handle products carefully to prevent damage from dropping or improper removal.
- Terminals: Do not bend terminals with excessive stress to prevent 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: Preheat components before soldering. Temperature difference between solder and chip temperature should not exceed 150C.
- Soldering Correction: Perform soldering corrections within specified conditions. Overheating may cause short circuits, performance deterioration, or lifespan reduction.
- Self-Heating: Allow sufficient margin for thermal design due to self-heating when power is ON.
- Non-Magnetic Shield Type: Carefully lay out coils on the circuit board to prevent malfunctions due to magnetic interference.
