Panasonic's industrial power inductors include high robustness ETQP_M*** series devices and specially designed coils from the ETQP_L*** series which have a unique frame structure, allowing tight DCR tolerance and long lifetime.

  • Unique metal composite core material leads to special benefits: low saturation; low loss at high frequency; stability over temperature
  • Designed for harsh environments and a long life
  • Line-up ranges from 0.15μH to 100μH in case sizes from 5x5mm to 12x12mm
  • Special designs for low inductance, high current and tight DCR tolerances available
  • Recommended for filter and DC/DC applications



  • DC-DC converters
  • Input and output filters
  • Power actuators
  • Battery charging
  • ECU controllers
  • HIM displays

What value does Panasonic bring?

  • Higher power efficiency for battery applications.
  • Miniaturized ECU and power circuitry.
  • Longer working life in harsh environments.
  • Reduced number of designs.

Why Panasonic?

  • Robust design using metal composite core and a monolithic mold structure.
  • Variety of package sizes (5x5mm to 12x12mm)
  • Wide inductance range (0.2µH to 100µH) 
  • High vibration resistance (10G to 50G)
  • Stable temperature characteristics
  • High reliability automotive grades
  • Half the size of ferrite parts
