Note on Currents:
- 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.
- Special Remind: Circuit design, component, PCB trace size and thickness, airflow and other cooling provisions all affect the part temperature. Part temperature should be verified in the end application.

Reliability Testing
Various reliability tests are conducted according to international standards including GB/T, JIS, IEC, MIL-STD, and GJB. Key tests include 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
The recommended reflow conditions are set according to the manufacturer's soldering equipment. Users should adjust and confirm these conditions based on their specific environment and equipment. The peak temperature for reflow soldering should be 260+0/-5, with the process performed twice.
Reminders for Using These Products
- Storage: Within 12 months under conditions of 5~40C and 35~65% RH. Soldering of terminal electrodes may deteriorate if storage time elapses.
- Environment: Do not use or store in environments with gas corrosion (salt, acid, alkali, etc.).
- Handling: Avoid direct contact with terminals by hand due to oil secretions that can inhibit soldering. Handle products carefully to prevent damage.
- Terminal Bending: Do not bend terminals with excessive stress to prevent wire fracture.
- Cleaning: Do not rinse coils. Contact the manufacturer if cleaning is necessary.
- Magnetic Fields: Do not expose products to magnets or magnetic fields.
- Preheating: Preheat components before soldering. The temperature difference between solder and chip temperature should not exceed 150C.
- Soldering Corrections: Corrections after mounting should be within specified conditions. Overheating may cause short circuits, performance degradation, or reduced lifespan.
- Thermal Design: Allow for sufficient thermal design margin due to self-heating when power is on.
- Non-Magnetic Shield Type: Carefully lay out coils on the circuit board to prevent malfunctions due to magnetic interference.
