[Boatanchors] Electrolytics- How Much is Too Much

[J. Forster]

1.5 mA is probably OK for most purposes. The cap will dissipate aout 600
mW, which will not produce a lot of self-heating.

What would matter more is the trend-

If it's increasing, that's a bad sign.

If stable or decreasing over several hours, that's good.
