Hi Richard, In working with Steward ferrite on this I can answer - NO. There is no specific standard - but there is good engineering practice. Steward have developed an excellent test methodology that they are using to prove the efficacy of their ferrite pound for pound against the competition.

From: Georgerian, Richard [mailto:[email protected]] Sent: Friday, May 21, 2004 10:59 AM To: IEEE Subject: Ferrite core test methodology Greetings All, In regards to measuring for the Z impedance for ferrite cores and beads, is there a specific standard that ferrite vendors use to create such curves? For that matter, are there any such standards? I would suspect that if test set-ups and methodologies are different from vendor to vendor, comparing curves would not be too helpful. Any thoughts and comments would be appreciated. Thanks.
