Yea, the difference between uH (Micro-henries) & mH (mil-henries) is what I've always understood since my earliest training. But the fact that I have been unable to fine mH chokes & only found uH chokes made me wonder if the measurement system of inductors had changed!! (sort of like when capacitor measurements changed from uuF to pF) I was doing this search late last night. Today, a little more fresh, I'll go back to work & look at the Newark & Allied catalogs again! Perhaps I'll see something I missed. ------ Original Message ------ Received: Wed, 22 Dec 2004 09:35:50 PM CST From: Joe Montierth <[EMAIL PROTECTED]> > > --- JOHN MACKEY <[EMAIL PROTECTED]> wrote: > > I need to build a filter and it requires I have a > > few chokes of 2.2 mH value. > > So I look in the Newark & Allied catalogs and all > > the chokes I am seeing are > > labeled "�H" (a "u" with a tail on the left) > > rather than "mH" > > > > Was I asleep for a long period of time & they > > changed how inductors/chokes are > > labeled or am I missing something else? > > The m is for milli, the u (with the tail) is for > micro.
