Identify small black cubic component with 2 pins
This is probably a 47 pF 100 V capacitor.

Capacitance values on small parts like this are almost always expressed in a floating point format.  In this case, most likely, the first two digits are the mantissa and the last the exponent of 10.  "470" therefore means "47 x 100".  We guess that the units is pF, but that is almost universally the case.
