Definitions:
- Saturation Current (Isat): DC current at which inductance drops 30% from its value without current.
- Heat Rating Current (Irms): The actual value of DC current when the temperature rise is T 40 (Ta=25).
- Rated DC Current: The lesser value between Isat or Irms.
- Note: Part temperature is influenced by circuit design, component placement, PCB trace size and thickness, airflow, and other cooling provisions. Verify part temperature in the end application.
Environmental Data
- Operating Temperature: -40 to +125 (Including coil self-temperature rise)

Reminders for Using These Products
- Storage: Within 12 months, under conditions of 5~40C and 35~65% RH.
- Environment: Avoid use and storage in corrosive gas environments (salt, acid, alkali, etc.).
- Handling: Avoid direct contact with terminals due to hand oils affecting solderability. Handle with care to prevent damage.
- Terminal Bending: Do not excessively bend terminals to avoid wire fracture.
- Cleaning: Do not rinse coils; contact the manufacturer if cleaning is necessary.
- Magnetic Fields: Keep away from magnets or magnetic objects.
- Preheating: Preheat before soldering; temperature difference between solder and chip should not exceed 150C.
- Soldering Corrections: Perform within specified conditions; overheating can cause issues.
- Thermal Design: Allow sufficient margin for self-heating when power is on.
- Layout: For non-magnetic shield types, careful coil placement is needed to avoid malfunction due to magnetic interference.
