Quick lesson in capacitor markings:

The number '104' indicates the capacitance, with the first two digits '10'
being the 'mantissa' or value and the last digit being the exponent.
Ceramic (and other caps marked like this) are all rated in pF or 10^-9 F.
Therefore, this cap is 10x10^4pF or 100,000pF, or 0.10uF. The other
capacitor, 224Z, would be 0.22uF (22x10^4pF). The 'Z' specifies a
temperature range (IIRC) or something else that is not terribly important
for most applications.
