Core Selection Tool

Guidance based on published engineering content. Output is directional, not a final specification — final selection requires engineering review with your real operating profile.

Suggested direction

FeNi powder core / molded metal composite (YTMF)

Core shapes: Molded SMD inductors, toroids

  • • 1–100 MHz: core loss dominates; FeNi/metal composite keeps permeability stable under bias.
  • • Size priority favors the highest-Bs material that still meets loss (FeNi vs ferrite).
