Definitions:

  • Saturation Current (Isat): DC current at which inductance drops 30% 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.

Cover tape peel off condition:

  • a) Cover tape peel force shall be 10 to 120g
  • b) Noodle strip peeling angle 165 to 180

Recommended Reflow Soldering Curve:

The recommended reflow conditions are set according to the soldering equipment. Users should adjust and confirm conditions based on their specific environment and equipment.

Reminders for Using These Products:

  • Storage period is within 12 months. Storage conditions: temperature 5~40C, humidity 35~65% RH or less.
  • Do not use or store in environments with gas corrosion (salt, acid, alkali, etc.).
  • Avoid direct contact with terminals by bare hands due to oil secretions affecting solderability.
  • Handle products carefully to prevent damage from dropping or improper removal.
  • Do not bend terminals with excessive stress to avoid wire fracture.
  • Do not rinse coils without authorization; contact the manufacturer if cleaning is necessary.
  • Do not expose products to magnets or magnetic fields.
  • Preheat components before soldering; the temperature difference between solder and chip should not exceed 150C.
  • Soldering corrections after mounting should be within specified conditions to avoid short circuits, performance degradation, or reduced lifespan.
  • Allow for sufficient thermal design margin due to self-heating when power is on.
  • For non-magnetic shielded types, carefully lay out coils on the PCB to prevent malfunctions due to magnetic interference.
