Notes on Current Ratings:

• Saturation Current (Isat): DC current at which inductance drops 10% from its value without current.
• Temperature Rise Current (Irms): The actual value of DC current when the temperature rise is T 40 (Ta=25).
• Rated DC Current: The lesser of Isat or Irms.
• Important Reminder: 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.

Packaging Information:

Reminders for Using These Products:

• Storage: Within 12 months, under conditions of 5~40C and 35~65% RH.
• Environment: Avoid use and storage in corrosive gas environments (salt, acid, alkali, etc.).
• Handling: Avoid direct contact with terminals with bare hands. Handle carefully to prevent damage.
• Bending: Do not bend terminals with excessive stress.
• Cleaning: Do not rinse coils; contact the manufacturer if cleaning is necessary.
• Magnetic Fields: Do not expose to magnets or magnetic fields.
• Preheating: Preheating is required before soldering; temperature difference between solder and chip should not exceed 150C.
• Soldering Corrections: Corrections after mounting should be within specified conditions to avoid overheating.
• Thermal Design: Allow sufficient margin for self-heating when power is applied.
• Layout: For non-magnetic shield types, careful coil placement is needed to prevent malfunction due to magnetic interference.
