Capacitor markings vary greatly from one
manufacturer to another as the above table shows.
Voltages may be marked directly (200V) or coded
(2D). The value of capacitance may be marked
directly on the part as shown in columns 4 and 5
(note that .001
μF and 1000μF have the same
marking, but the difference in size makes the value
obvious). The number 102 may also be used to
represent 1000 (10+2 zeros). In some instances the
manufacturer may use an R to represent the
decimal point. The tolerance is usually printed
directly on the capacitors. When it is omitted, the
standard tolerance is assumed to be +80% to –20%
for electrolytics. Capacitance change with
temperature is coded in parts per million per degree
C, {N220 = 220/1,000,000 or .022%}, or by a
temperature graph. See manufacturers
specifications for complete details.
CAPACITOR SYMBOLS
Figure 16 shows the schematic symbols used to represent
capacitors. The + symbol indicates that the capacitor is
polarized and the lead marked with the + sign must always
have a
higher voltage than the other lead. The curved
plate, plate with sides, and minus sign also indicate the
capacitor is polarized and these leads must always be at a
lower voltage than the other lead. The arrow crossing
through the capacitor indicates of capacitance is variable.
