Help ID SMD capacitors - 1997 IBM PCMCIA CD drive
Posted by: Byrd on 2023-10-27 16:49:15
Hi all,

I've got this 1997 IBM PCMCIA CD data/audio drive (as used in ThinkPads), it has an integrated sound card, producing a lot of audio noise and unable to read media although it tries.

About five SMD caps look as if they are leaking but can't work out the naming, this is what's listed on the capacitors:

7N, 220, 6X (220uF 6V?)

70, 100, 6X (100uF 6V?)

70, 47, 6X (47uF 6V?)

70, 10, 25X (10uf 25V?)

70, 22, 10X (22uf 10V?)

They're not super common cap ratings so keen to check.

Thanks

JB
