Definitions:

• Saturation Current: DC current at which inductance drops 10% from its value without current.
• Temperature Rise Current: 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 period is within 12 months. Storage conditions: temperature 5~40C, humidity 35~65% RH or less.
• Do not use or store in environments with gas corrosion (salt, acid, alkali, etc.).
• Avoid touching electrodes directly with bare hands to prevent inhibiting soldering.
• Handle products carefully to prevent damage from dropping or improper removal.
• Do not bend terminals with excessive stress to avoid wire fracture.
• Do not rinse coils. Contact the manufacturer if cleaning is necessary.
• Do not expose products to magnets or magnetic fields.
• Preheat components before soldering. The temperature difference between solder and chip should not exceed 150C.
• Soldering corrections after mounting should be within specified conditions. Overheating may cause short circuits, performance deterioration, or lifespan reduction.
• Allow sufficient thermal design margin for self-heating when power is applied.
• For non-magnetic shield types, carefully lay out coils on the PCB to prevent malfunctions due to magnetic interference.
