Current Definitions
- 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 of Isat or Irms.

Reminders for Using These Products
- Storage: Within 12 months, under conditions of 5~40C and 35~65% RH. Soldering of terminal electrodes may deteriorate if storage period elapses.
- 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 that can inhibit soldering. Handle products carefully to prevent damage from dropping or improper removal.
- 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: Do not expose products to magnets or magnetic fields.
- Preheating: Preheat components before soldering. The temperature difference between solder and chip temperature should not exceed 150C.
- Soldering Corrections: Post-mounting soldering corrections should be within specified conditions. Overheating may cause short circuits, performance degradation, or reduced lifespan.
- Thermal Design: Allow sufficient margin for thermal design due to self-heating when power is on.
- Non-Magnetic Shield Type: Carefully lay out coils on the PCB to prevent malfunctions due to magnetic interference.
