Max31855 v2 ferrite bead replacement

Post by bheiss »

I have dammaged what seems to be one of the ferrite beads on the board. (element right of "Red")
With what can I replace the ferrite bead and/or what are the specification of the element, so that I can replace it ?

Schematics that I found on Github seem to be showing Max31855 V1 board ( https://github.com/adafruit/Adafruit-MA ... kout-board) without any beads.

Tx for your advise !

Encl.: v2 board with dammaged ferrite bead ?

you can use any ferrite bead but a piece of wire will suffice as well, there's two beads and a capacitor - the capacitor is the most important part :)

Tx !
Soldering a piece of wire instead of a bead solved my problem !

Hello, please, can you write, which ferrite is really used in original - which parameters does it have?

Have the same problem as bheiss...

Thanks!

I think we're using 300 ohm 0805s right now, but the value isn't specified because it isn't critical, or even important.

I know this is an old post, but for those looking for reference might look at Maxim Eval Board details, including schematic:
