Current Definitions:

Saturation Current (Isat): Current at which inductance becomes 10% lower than its initial value (Ta=25).
Temperature Rise Current (Irms): Actual DC current when temperature rise is T 40 (Ta=25).
Rated DC Current: The lesser value between Isat and Irms.

Recommended Lead-free Wave Soldering Curve (DIP-Type):

Refer to manufacturer's recommendations and adjust based on user's environment/equipment.

Soldering Iron (Rework):

Use soldering iron, temperature not exceeding 350 degrees, max 3 times.
Avoid contacting the inductor body or wire during soldering.
Hand soldering with a soldering iron is not recommended.

Reminders for Using These Products:

Storage: Within 12 months, under 5~40C and 35~65% RH. Deterioration of terminal solderability may occur if storage period is exceeded.
Environment: Do not use or store in gas corrosive environments (salt, acid, alkali, etc.).
Handling: Avoid direct contact with terminals due to hand grease affecting solderability. Handle carefully to prevent damage from dropping. Do not excessively bend terminals.
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 should not exceed 150C.
Soldering Correction: Perform corrections within specified conditions. Overheating may cause short circuits, performance degradation, or reduced lifespan.
Self-heating: Account for self-heating (temperature increase) when power is on in thermal design.
Layout: For non-magnetic shield types, careful coil placement on the PCB is required to prevent malfunctions due to magnetic interference.
