Note: 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. Part temperature should be verified in the end application.

Reminders for Using These Products
- Storage period is within 12 months under conditions (temperature: 5~40C, humidity: 35 to 65% RH or less).
- Do not use or store in gas corrosive environments (salt, acid, alkali, etc.).
- Avoid direct contact with terminals due to oil secretions.
- Handle products carefully to prevent damage.
- Do not bend terminals with excessive stress.
- Do not rinse coils; contact the manufacturer if cleaning is necessary.
- Do not expose products to 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 to avoid overheating.
- Allow sufficient margin for thermal design due to self-heating when power is on.
- For non-magnetic shield types, careful PCB layout is needed to prevent malfunctions due to magnetic interference.
