Recommended Lead-free Wave Soldering Curve (DIP-Type)
A recommended wave soldering curve is provided as a reference. Users should adjust and confirm soldering conditions based on their specific environment and equipment. Hand soldering with a soldering iron is not recommended, but if necessary, should not exceed 350 degrees and should avoid direct contact with the inductor body.
Reminders for Using These Products
- Storage: Within 12 months under conditions of 5~40C and 35~65% RH.
- Environment: Avoid gas corrosive environments (salt, acid, alkali).
- Handling: Avoid direct contact with terminals due to oil secretions. Handle carefully to prevent damage. Do not excessively bend terminals.
- Cleaning: Do not rinse coils; contact the manufacturer if cleaning is necessary.
- Magnetic Fields: Keep away from magnets or magnetic objects.
- Soldering: Preheat components before soldering (temperature difference
- Thermal Design: Account for self-heating when the device is powered on.
- Layout (Non-magnetic Shield Type): Carefully consider coil placement on the circuit board to prevent malfunctions due to magnetic interference.
