Re: RF filtering resistors

i'm planning on using an air core choke / resistor setup as part of my RF
filtering circuit, but when i went to purchase
the resistor ( 500 ohm 50 watt) i noticed that it was coil wound like an
inductive coil ( it had 100 to 200 turns or so , pretty much closely wound,
on about a 5/8 inch diameter ceramic tube about 4 inches long. can i
calculate the inductance of this and
use this value as part of the filtering capability, or is the standard to
"ignore" this intrinsic value of the resistor
and use a separate choke to provide the necessary inductance? - thanks for
any advice, doug
