[Boatanchors] is it a Choke or a Filter Reactor?

[rkerr]

Greg,
"Reactor" refers to the inductor's positive reactive AC circuit 
impedance.  "Choke" whether for a DC power supply filter or for higher 
frequencies ("RF choke") refers to the blocking effect of the inductor 
for higher frequencies, that is, DC currents are passed with little 
loss, while higher frequencies are diminished or "choked" off.   That 
said, I don't know of any industry standard technical distinction 
between the terms "Filter Choke" and "Filter Reactor" when referring to 
big, heavy, iron core inductors used in DC power supply filter 
circuits.  I believe these are just two interchangeable terms used to 
refer to the same thing.
