Mouser part # for ferrite beads?

Re: Mouser part # for ferrite beads?

I have used that part number and also 623-2743002112. The 1112 part is
680 ohms @ 100Mhz and the 2112 is 1330 ohms at 100Mhz. Does it really
matter that much? I wonder if it depends on the filter capacitor used.
MOTM uses a 10uf value while Oakley uses a 22uf. The purpose of the
bead is to add impedance at high frequencies, which might enter on the
power supply cable as RF noise from nearby computers, cell phones, and
radios. I suppose the value depends on the frequencies you are trying
to eliminate.

No, it doesn't. Use a wire link, or a 10 ohm resistor instead if you like.

I just use beads I have to hand - I don't even bother going out to source
particular types. In a way, it's like arguments over which sort of wire
connected to your speakers sounds better - stuffed if I know the answer to
that one - my ears, while excellent, obviously don't have the "resolution"
of those of an audiophile!
