[sdiy] wall warts--wishful thinking

[Scott Stites]

Don't know if this would even apply (looks to be built more for high freq
DC-DC convertors), but the latest BGMicro flyer had this item:

"FLTR100V20 filter module.  Optimized for use with high frequency dc to dc
power modules.  This module is designed to reduce the conducted common-mode
and differential-mode noise on input or output lines of high frequency
switching power supplies.  The module has a maximum current rating of 20A.
Measures 2"x1-9/16".

Made by Lucent.  BGMicro P/N PWR1202  $1.99 each.
