Tri - Coil Construction
Resonant Choke Coils are composed of 430F or 430FR inductance stainless steel film coated wire (typically .004 Ga. Or smaller) which are axially Bifilar wound about core bobbin, forming individual spiral-wrap electrically connected in sequential order to form resistive pickup coil.
Primary Coil (typically .030 Ga.) film coated magnet wire is longitudinal wrapped in space relationship on top of and layered bi-directional across spiral-wrap coils to complete bobbin cavity.
Secondary pickup coil is, also, composed of individual spiral wrapped coils (typically .002 Ga. magnet wire) electrically connected in sequential order to form bobbin cavity, which is placed on top of, and in space relationship to primary coil cavity

Inductor and Inductor is wound or coil-wrapped in such a manner as to increase the magnetic flux intensity of coil-wrap. The circular-spiral turns of wire is separated by an Insulated Dielectric Coating Material which forms a series of capacitors when magnetic flux-lines produces Electromagnetic Coupling Field during pulse on-time. The series resistance value is determined by ~e composition of the wire material in terms of its ohmic value per given length and diameter cross-section: Resonant Charging Chokes 430F/FR 36 A WG (.006) stainless steel (s/s) wire

equals 60 micro ohms per centimeter; Primary Coil 22 A WG (.028) copper wire equals 5.1933 ohms per pound weight; Secondary Pickup Coil 35 A WG (.007) copper wire equals 13K ohms per pound weight. "Pyre-ML" trade name "Himol" polymer coating-material is used to impart thermal and mechanical resistance to the stainless steel (s/s) wire (614/615) coating; both magnet wire sizes uses solderable Nysol (Polyurethane Nylon Jacket) insulation enamel coating as a electrical shield-material ... all dielectric coatings having an effective 3KV per mil dielectric value and formulated
