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 wave soldering curve is a reference. Adjust and confirm based on user's environment and 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, 5~40C, 35~65% RH. Solderability may deteriorate after storage period.
- Environment: Avoid gas corrosive environments (salt, acid, alkali).
- Handling: Avoid direct contact with terminals due to hand oils affecting solderability. 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 may cause short circuits, performance degradation, or reduced lifespan.
- Self-heating: Allow sufficient margin for thermal design due to self-heating when powered on.
- Layout: For non-magnetic shield types, carefully consider coil placement on the PCB to prevent malfunctions due to magnetic interference.
