In Reply to: Re: A cheap parallel filter is the Hammond 193L choke. posted by pboser@yahoo.com on March 25, 2007 at 07:08:23:
The Hammond 193L is a 5 Henry inductor, so it will draw about 64 milliamps of reactive current with 120 VAC across it. Some of this will cause heating due to core and resistive losses, but the device should run cool. You may occasionally find one that buzzes due to loose laminations.The device will absorb higher-frequency noise and voltage spikes due to the characteristics of the magnetic core. It will not affect dynamics, as it is wired in parallel with the load.
Be sure the chokes you use have a high voltage rating for the insulation, to withstand surges before the core absorbs them.
