SMD Coupled Inductors for Automotive Buck-Boost

Sumida has added the CDRH127B a 2-in-1 type space saving SEPIC inductor which is suitable to buck-boost power supply converter for automotive applications.

Targeting application of this solution are LED head lighting, audit and others which need buck-boost power supply in limited PCB installation space.

These inductors have maximum saturation current ratings from 450mA to 10A and inductances from 470μH to 4.7μH. Maximum DCR ratings range from 29mΩ to 1.88Ω. These inductors can be wired as a single winding, leads connected in series or leads connected in parallel, to suit the specific needs of the application.

CDRH127B key features:

  • Ferrite drum ring structure
  • Magnetically shielded
  • Size: 12.3 × 12.3 × H8.0 mm Max.
  • Qualified AEC-Q200
  • 2 coils in 1 package for Sepic topology
  • Operational Temperature range: -40°C to +125°C (including self-heating)
