Balun, Balun... who's got the balun -

Posted by pmkap on December 11, 2002 at 09:05:10:
Certainly not the UltimateOutlet.... tis certainly not used as a balun, but rather as a CMC, common mode choke. The description as a balun is simply marketing hyperbole, at best. What differentiates the UO from other line filters that use a cmc, Corcom, Qualtek, etc... is that the UO uses a oversized, powdered iron torroid, #26 mixture, as opposed to the typical, easily saturated ferrite composition. What this allows is that it not only functions as a cmc (with caps as in most line filters) for dealing with common mode noise, but that not easily saturable formulation allows the windings to function as low inductance, independent chokes in dealing with differential noise.
Its a sad commentary that a well designed, clever device is marketed with specious nonsense, the nonsensical description of a balun (balanced to unbalanced) oft repeated by gullible reviewers, lowered impedence??? total bushwa!!!.... sad indeed.
