Webb3 juni 2015 · Table 1. Spacing → is the ratio of distance between center point of turns divided by the wire diameter. So a closely wound coil using 0.25 mm wire would have approximately 10% wider diameter from varnish, that makes it 0.275 mm / 0.25 mm = 1.1 spacing ratio. Ratio ↓ is the height/width ratio of the secondary coil. Webb22 sep. 2024 · The windings in the secondary also have some parasitic capacitance. Generally speaking, it is safe to say that the primary tank circuit is made up of a high capacitance and low inductance with a certain resonant frequency, and the secondary tank circuit is made up of a low capacitance and high inductance with a similar frequency.
