CAPACITANCE
This is expressed
in picofarads. The
first two digits are
the significant
figures. The third
is the number of
zeros to follow.

CAPACITANCE
TOLERANCE
X0 = ± 20 %
X9 = ± 10 %

DC VOLTAGE RATING
This is expressed in volts.
To complete the
three-digit block, zeros
precede the voltage rating.
A decimal point is indicated
by an “R” (6R3 = 6.3 V).
