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.
- Environment: Avoid use and storage in gas corrosive environments (salt, acid, alkali, etc.).
- Handling: Avoid direct contact with terminals due to hand oils; handle carefully to prevent damage.
- Terminal Bending: Do not excessively bend terminals to prevent wire fracture.
- Cleaning: Do not rinse coils; contact the manufacturer if cleaning is necessary.
- Magnetic Fields: Keep away from magnets or objects with magnetic force.
- Preheating: Ensure preheating before soldering to maintain a temperature difference within 150C between solder and chip temperature.
- Soldering Corrections: Perform within specified conditions to avoid performance degradation or reduced lifespan.
- Thermal Design: Account for self-heating when the device is powered on.
- Non-magnetic Shield Type: Careful layout is required on the PCB to prevent malfunction due to magnetic interference.
