Specifying form wound coils is easy.
Here is all we need from you:

  • Inside dimensions and shape.
    (NOTE: tooling sets the inside dimension and
    the outside dimension is determined by the winding.)

  • Required thickness.

  • Inductance with tolerance and the measurement frequency.

  • Wire gauge and any special insulation requirements.

  • Lead wire length and position.

  • Number of turns (optional)

  • Coil resistance (optional)
