[Elecraft] Toroids - Effect of Winding Spacing on Inductance and Distributed Capacitance

[Jack Smith]

Since toroid inductors are used throughout the K2, and since few other 
topics generate as much discussion and the care and feeding of 
toroid-wound inductors, I wanted  to mention that Andy, G4OEP, has 
recently completed an interesting study of the effect of turns spacing 
upon inductance and distributed capacitance, which may be read at 
http://g4oep.atspace.com/coil/coil.htm.

I also recommend Andy's other work, linked at his home page 
http://g4oep.atspace.com/index.htm,

I've also added a new page to my site showing the effect of voltage on a 
variety of ceramic capacitors. 
http://www.cliftonlaboratories.com/capacitor_voltage_change.htm. It 
provides at least a start of an answer to the question "when is a 0.1uF 
capacitor not a 0.1uF capacitor"?
