Hook 'em up to 600V. If they don't smoke, they're OK. ;-)

.22uF. "224" is capacitor-speak; it works like this:

The first two digits are the value, and the last digit is
the multiplier. (22 followed by four zeros, in this case.)
The result is in pF. Move the decimal point six places
to the left to get uF.

Scott, re your capacitors.. they should be .22uf.

The formalism with the part # is as follows:
221K = 220uf
222K = 22uf
223K = 2.2uf
224K = .22uf
225K = .022uf
226K = .0022uf and on

also the other question re caps in parallel. the voltage rating of
the caps stays the same when in parallel and doubles when in
series. three in series triples and so on. warning though, with
series caps, leakage in one or more of the caps will skew the
overall voltage rating downward. and kaboom.

Kelly:

You have been correctly shown that the 224 part of the nomenclature is 0.22
µf (22 followed by 4 zeros - pf.). The leading 2J and the K suffix indicate
the voltage and tolerance/stability. But, I can no longer find my magic
decoder ring, and I would be very suspicious of the voltage rating, as Japan
manufactured very few "high voltage" capacitors over 200V. 50V, 100V,and
200V are plentiful; 400V are rare and 600V difficult to find. As a guess, I
would suspect those are 200 volt jobs.
