Core selection

The core decides everything else

Window area, leakage inductance, copper loss and how tall the finished part sits on your board are all set before a single turn is wound. Seven geometries, each making a different trade.
  • EEThe default. Widest window for its size, easy to wind, cheap to tool.
  • EIE half plus a flat I bar. Lower cost, slightly higher stray field.
  • EFDFlat, low-profile section. For designs where board height is the constraint.
  • ETDRound centre limb. Shorter mean turn length, so lower copper loss at power.
  • PQRound limb in a square footprint. Best window-to-volume ratio of the set.
  • RMNearly closed pot. Strong self-shielding where EMI is the binding limit.
