Multilayer winding:
The winding pitch is equal to the wire diameter. The coil is wound with several layers. This leads to
parasitic capacitances between the layers in addition to the turn-to-turn capacitances. In compari-
son to all other types of winding, this type leads to the highest capacitances and thus the lowest
resonance frequencies.
Random winding:
The winding pitch is smaller than the wire diameter. The coil is wound in one direction only. This
method of winding a coil does not permit the final position of a turn to be predetermined exactly. The
cross section of this type of winding clearly shows a disorderly, “random” arrangement of the turns.
This leads to the parasitic capacitances being only minimally greater than those achieved by single-
layer winding, and the resonance frequencies are equal to those achieved by single-layer winding.
