I have some surface mounted capacitors on an MS-6712 which I believe have gone bad. There are 4 of them on the board, and I get the following readings with an ESR meter:
ec35=0.27ohms <next to southbridge>
ec40=9.7ohms <visible in photo, near battery>
ec41=9.9ohms ""
ec46=4.3ohms <just below the photo, also near battery>
All of these have
10
16S
L33
stamped on them.
Since the readings are so inconsistent, I assume the high readings are units that have gone bad.
10 16S L33
I'm reading that as 10uF 16V, and I don't know what L33 is. "S" might be a series code. I'm using the Teapo SV datasheet as a guideline for how to read these numbers. If it's really a Teapo, then it should be SV series because of the "S". Of course Teapo is the only site I checked, so it could be anything really. They don't seem to explain their code numbers.
Am I misinterpreting this? I'd like to sanity check my specs before I draw conclusions about what parts to order. I haven't dealt with SMT caps before.
