Current Definitions

Saturation Current (Isat): DC current at which inductance drops 10% from its value without current.
Temperature Rise Current (Irms): 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.

Reliability Testing

Refer to the provided datasheet for detailed reliability testing information including Terminal Strength, Resistance to Flexure, Dropping, Solderability, Vibration, Thermal Shock, Low Temperature Storage, High Temperature Storage, Damp Heat, Heat endurance of Reflow soldering, Resistance to solvent test, Overload test, and Voltage resistance test.

Recommended Lead-free Wave Soldering Curve (DIP-TYP)

Recommended reflow conditions are provided based on specific soldering equipment. Users should adjust and confirm conditions based on their environment and equipment.

Reminders for Using These Products

Storage: Within 12 months, temperature 5~40C, humidity 35~65% RH.
Environment: Avoid gas corrosive environments (salt, acid, alkali).
Handling: Avoid touching terminals with bare hands; handle carefully to prevent damage.
Bending: Do not excessively bend terminals.
Cleaning: Do not rinse coils; contact manufacturer if cleaning is required.
Magnetism: Keep away from magnets or magnetic objects.
Preheating: Preheat components before soldering; temperature difference between solder and chip should not exceed 150C.
Soldering Corrections: Perform within specified conditions to avoid performance degradation or reduced lifespan.
Self-heating: Account for self-heating in thermal design.
Layout: For non-magnetic shield types, careful PCB layout is needed to prevent malfunction due to magnetic interference.
