In investigating the fault on my H7874 PSU I desoldered a tantalum capacitor
which I have broken in the desoldering process. I can't tell its value, the
markings are 224 E5Z on one side and 038 ASF on the other side.
The value is given by '224' You read that like the resisotr code, that is
22*10^4, or 2200000. The 'base unit' for cpaacitors is the picofarad
(pF), so that's 220000 pF = 220 nF = 0.22 uF.
That sounds low for a tantalum capacitor. I'#ve actually seen tantalum
capacitors down to 0.1uF, but most are >1uF Are you sure it's tantalum?
