High Reliability Inductors    HER1090C

Features

  • Compact and Low profile Power Inductor for Automotive-Equipments
  • Upgraded the current characteristics by using different magnetic materials for drum core and ring core separately
  • *The current characteristics have been increased by approximately 20% as compared with the same sized existing product
  • HER8080C realizes the current characteristic equivalent to our 10mm SQUARE coils
  • HER1090C realizes the same current characteristic equivalent to our 12mm SQUARE coils
  • AEC-Q200 compliant
  • Operating temperature:-40℃~+150℃(The self-heating is included)

Applications

  • Automotive
  • Car Audio, Car Navigation, ECU, LED Headlights
  • Others
  • Power Supply, FA, Medical, Energy
