Definitions:
- Saturation Current: DC current at which inductance drops 30% 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: Within 12 months. Conditions: Temperature 5~40C, Humidity 35~65% RH or less.
- Avoid use and storage in corrosive environments (salt, acid, alkali, etc.).
- Avoid direct contact with terminals by bare hands to maintain solderability.
- Handle products carefully to prevent damage from dropping or improper removal.
- Do not bend terminals excessively to avoid wire fracture.
- Do not rinse coils. Contact SXN if cleaning is necessary.
- Keep away from magnets or magnetic fields.
- Preheat components before soldering. 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 degradation, or reduced lifespan.
- Allow for sufficient thermal design margin due to self-heating when power is on.
- For non-magnetic shielded types, careful coil layout on the PCB is required to prevent malfunctions due to magnetic interference.
