Electrical Characteristics (at 25)

Note 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.
• Special 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.

Product Packaging:

Reminders for Using These Products:

• Storage: Within 12 months, under conditions of 5~40C and 35-65% RH.
• Environment: Avoid use or storage in corrosive gas environments (salt, acid, alkali, etc.).
• Handling: Avoid touching terminals directly with bare hands to prevent reduced solderability. Handle carefully to prevent damage.
• Terminal Bending: Do not bend terminals with excessive stress to avoid wire fracture.
• Cleaning: Do not rinse coils; contact the manufacturer if cleaning is necessary.
• Magnetic Fields: Keep away from magnets or magnetic objects.
• Soldering: Preheat components before soldering. The temperature difference between solder and chip should not exceed 150C.
• Post-Mounting Correction: Ensure soldering corrections are within specified conditions to avoid performance degradation or reduced lifespan.
• Self-Heating: Account for self-heating when power is applied in thermal design.
• Layout: For non-magnetic shield types, careful PCB layout is required to prevent malfunctions due to magnetic interference.
