Can someone help me understand the labeling of the silver capacitor ?
It is part of the voltage regulation of a scope15 card, which runs very unstable.
It labeled:
1
50S
0K0

The common guides only explain different labeling styles.

1 microFarad, 50V would make sense at that position (Vcc2 Gnd).

Thanks. My inital guess was the same, but "S" and "K" confused me.
I'll order now and try replacing.
