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 .001μF 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.
