Current Definitions:

• 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 value of Isat or Irms.

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 electrodes directly 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.
• Soldering: Preheat components before soldering; ensure the temperature difference between solder and chip does not exceed 150C.
• Post-Mounting Corrections: Perform within specified conditions to avoid performance degradation or reduced lifespan.
• Thermal Design: Account for self-heating when power is applied.
• Layout: For non-magnetic shield types, careful PCB layout is required to prevent malfunction due to magnetic interference.
