must be the ferrite cores ... for example, on an external disk drive, the cable is about 18inches long, on one end there is a pcmcia connector and card, the disk drive end uses some type of 36 pin connector to plug into the back of the drive, but right before this 36 pin thing, there is a 1 inch diameter X 1.5 in long, cylinder around the round, cable... is this a ferrite core, or some type of connector?? thanks... ----- Original Message ----- From: "Chris Carr" To: Sent: Friday, March 02, 2001 1:46 PM Subject: Re: [ot]: cable hardware question?? > > alright I've had it with these short, stubby, damn computer cables... > > > > my question is, what are the cylinders in between the connectors > > of disk drive and other computer cables? > > > > are they some type of connector? if so, what are they called and > > where can you get them, > > I'm guessing you are referring to the ferrite cores, they are there to > reduce electrical noise. > > Any broadline distributor.
