Re: [TCML] Sprague 4000MMFD caps



Hi Dave, 

Looks like you were asking a question about .004 ufd  being equal to 4000 mmfd (pFd).  4000 (10 e-12) Farads would indeed equal .004 (10 e-6) Farads :-)  The mmfd (micro-microfarad ~10 e-12 or one-trillionth of a Farad) is now a pretty much archaic term and is now usually expressed as a pFd (picofarad). Of course, it could also be expressed as 4 nFd (nanofarads)
