For high power inductor applications in low pass or bandpass filters, antenna tuners, etc.; we need to select an iron powder core that will
	deal with the power without failure.  Failure in these applications is typically due to heating caused by core losses, which are greater at
	lower frequency.  Losses in the wire used to wind the inductors, which are greater at higher frequency, can also be an issue,
	and are treated at the bottom of the page.
	To compute the core loss, you need the AC flux loss formula for your material type, which can sometimes be found on the web.  As it happens,
	#2 material and #6 material are the most commonly used, and their loss curves are very similar.  We can use #6 material as a proxy for both.
	#17 material is lower loss than #6, but exactly how much lower isn't know even by the manufacturer, Micrometals.
	Always remember that #0 material, phenolic material, has no core loss - and thus can and should be used if it is possible to fit enough wire
	onto the core to deliver the inductance required.
	To compute the core loss, and the temperature rise resulting therefrom, use the following formulae or find your data in the sample charts below.
	You can download this spreadsheet at http://www.k6if.com/coreLossCalcs.xls.  Temperture rise is linearly related to voltage,
	so you can use these data tables and multiply or divide from the reference 375 volts if you please.
	Temperature rise greater than 50 degrees C will result in permanent damage to the core, and should be avoided (assuming 25 C ambient temp.).
	Bmax (max flux density in gauss)			= (Voltage * 10 ^ 2) / (4.44 * Cross Sectional Area in cm^3 * Turns * Frequency in mHz)
	Core Loss for #6 material in mw			= 8.34 * 10 ^ -10 * Frequency in Hz ^ 1.15 * Bmax ^ 2.17 * Core Volume in cm^3
	Temperature Rise in degrees C			= (Core Loss / Surface Area) ^ 0.833
	In a 50 ohm system:
	At 3:1 SWR max RMS volts is			450	and max RMS amps is			9																									1.4:1 @ 100 watts is 81 volts RMS
	At 2:1 SWR max RMS volts is			375	and max RMS amps is			7.5
