Usage Reminders

  • Storage Period: Within 12 months. Storage conditions: temperature 5~40C, humidity 35~65% RH or less.
  • Environment: Do not use or store in locations with gas corrosion (salt, acid, alkali, etc.).
  • Handling: Avoid direct contact with terminals using bare hands due to oil secretions affecting soldering. Handle products carefully to prevent damage from dropping or improper removal.
  • 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: Post-mounting soldering corrections must be within specified conditions. Overheating may cause short circuits, performance degradation, or reduced lifespan.
  • Thermal Design: Allow sufficient margin for thermal design due to self-heating when power is applied.
  • Layout (Non-Shielded Type): Carefully lay out coils on the PCB for non-magnetic shielded types to prevent malfunctions due to magnetic interference.
