Choke Design

Inductor/Choke Fundamentals Inductors, commonly called "chokes" in VIC terminology, are the workhorses of the resonant circuit. They store energy in their magnetic field and, toget...

Core Materials & Properties The core material of an inductor dramatically affects its performance. Choosing the right core is essential for achieving the desired inductance, Q...

Wire Gauge & Material Selection The wire used to wind an inductor directly affects its DC resistance, current capacity, and Q factor. Proper wire selection is essential for max...

Bifilar Winding Technique Bifilar winding is a special technique where two wires are wound together in parallel on a core. This configuration creates unique electromagnetic propert...

Parasitic Capacitance & SRF Real inductors have parasitic capacitance between turns and layers that limits their useful frequency range. Understanding these effects is critical...

DC Resistance and Q Factor The DC resistance (DCR) of an inductor is the primary factor limiting its Q factor and thus the voltage magnification achievable in a VIC circuit. Unders...
