2 in 1 Class-D LPF Inductor for Automotive: C2DEPI60D70

June 15th 2022

C2DEPI60D70 is wound by flat wire and assembled with a Mn-Zn ferrite core.  The flat wire provides exceptionally low DC resistance.  Meanwhile, its mountability is improved by reforming the gap structure from “Top Surface Gap” to “Side Surface Gap”.

High-density mounting is possible by adapting the 2 in 1 product structure. C2DEPI60D70 is the smallest size product within the Sumida class-D LPF inductor series.

Key Features:

  • AEC-Q200 compliance
  • 2-in-1 structure offers space-saving
  • Magnetically shielded
  • Operating temperature range: -40℃~+125℃ (including coil's self temperature rise)



Best suited for automotive Digital Amplifier (Class-D Amp)

※1 Measuring frequency inductance at 100kHz.
※2 Saturation current: This indicates the value of D.C. current when the inductance becomes 25% lower than its initial value. (Ta=20℃)
※3 Temperature rise current: The actual value of D.C. current when the temperature of coil becomes △T=40℃. (Ta=20℃)
