Notes on Currents:
- Saturation Current: DC current at which inductance drops 30% from its value without current.
- Heat Rating Current: The actual value of DC current when the temperature rise is T 40 (Ta=25).
- Rated DC Current: The lesser value between Isat and Irms.
- Special remind: Circuit design, component, PCB trace size and thickness, airflow, and other cooling provisions all affect the part temperature. Part temperature should be verified in the end application.

Reminders for Using These Products
- Storage: Within 12 months. Conditions: 5~40C, 35~65% RH. Solderability may deteriorate beyond storage period.
- Environment: Do not use or store in gas corrosive environments (salt, acid, alkali, etc.).
- Handling: Avoid direct contact with terminals by bare hands due to oil secretions affecting soldering. Handle carefully to prevent damage from dropping or improper removal.
- Terminals: Do not bend terminals excessively to avoid wire fracture.
- 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 Corrections: Perform after-mounting corrections within specified conditions. Overheating may cause short circuits, performance degradation, or reduced lifespan.
- Thermal Design: Account for self-heating when power is ON. Ensure sufficient thermal design margin.
- Non-Magnetic Shield Type: Careful layout is required on the circuit board to prevent malfunctions due to magnetic interference.
