Current Definitions:
- Saturation Current (Isat): Current at which inductance drops by 10% from its initial value (Ta=25).
- Temperature Rise Current (Irms): DC current causing a temperature rise of T 40 (Ta=25).
- Rated DC Current: The lesser value between Isat and Irms.

Recommended Lead-free Wave Soldering Curve (DIP-Type):
Note: The recommended curve is a reference. Adjust and confirm based on user's environment/equipment.
Soldering Iron (Rework):
- Hand soldering: Max 350 degrees, not exceeding 3 times.
- Avoid contacting the inductor body or wire during soldering.
- Hand soldering is not recommended.
Reminders for Using These Products:
- Storage: Within 12 months, under 5~40C and 35~65% RH. Terminal solderability may deteriorate beyond this period.
- Environment: Avoid gas corrosive environments (salt, acid, alkali).
- Handling: Avoid touching terminals directly with bare hands to prevent soldering inhibition. Handle carefully to prevent damage from dropping.
- Terminals: Do not bend terminals excessively to avoid wire fracture.
- Cleaning: Do not rinse coils. Contact the manufacturer if cleaning is necessary.
- Magnetism: Keep away from magnets or magnetic objects.
- Preheating: Preheat components before soldering. Temperature difference between solder and chip should not exceed 150C.
- Soldering Correction: Perform within specified conditions. Overheating may cause short circuits, performance degradation, or reduced lifespan.
- Self-heating: Allow sufficient thermal design margin as devices generate heat when energized.
- Non-magnetic Shield Type: Careful coil layout is required on the PCB to prevent malfunction due to magnetic interference.
