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.

Reliability Testing
Testing includes Terminal Strength, Resistance to Flexure, Dropping, Solderability, Vibration, Thermal Shock, Low temperature Storage, High temperature Storage, Damp Heat (Steady States), Heat endurance of Reflow soldering, Resistance to solvent test, Overload test, and Voltage resistance test. Specific requirements and test methods are detailed in the original documentation.
Recommended Reflow Soldering Curve
Refer to the original documentation for the recommended reflow soldering curve. Users should adjust and confirm conditions based on their specific environment and equipment.
Reminders for Using These Products
- Storage: Within 12 months, under conditions of 5~40C and 35~65% RH.
- Environment: Avoid 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 avoid 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: Preheat before soldering; temperature difference between solder and chip should not exceed 150C.
- Soldering Corrections: Perform within specified conditions; overheating may cause issues.
- Thermal Design: Allow sufficient margin for self-heating when power is on.
- Layout: For non-magnetic shielded types, careful coil placement on the circuit board is required to prevent malfunctions due to magnetic interference.
