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 lower value of Isat or Irms.

Recommended Lead-free Wave Soldering Curve (DIP-Type):
Refer to manufacturer's recommendations and adjust based on user environment/equipment.
Soldering Iron (Rework):
- Max temperature: 350C, max 3 times.
- Avoid direct contact with the inductor body and wire.
- Hand soldering is not recommended.
Reminders for Using These Products:
- Storage: Within 12 months, at 5-40C and 35-65% RH. Solderability may deteriorate after storage.
- Environment: Avoid gas corrosive environments (salt, acid, alkali).
- Handling: Avoid touching terminals directly with bare hands. Handle carefully to prevent damage from dropping. Do not excessively bend terminals.
- Cleaning: Do not rinse coils; contact manufacturer if cleaning is necessary.
- Magnetism: Keep away from magnets or magnetic fields.
- Preheating: Preheat components before soldering; temperature difference between solder and chip should not exceed 150C.
- Soldering Correction: Perform within specified conditions; overheating can cause issues.
- Self-heating: Account for self-heating in thermal design.
- Layout: For non-magnetic shield types, careful PCB layout is needed to avoid malfunction due to magnetic interference.
