Capacitor Color Codes for Identification Chart Capacitors may be marked with 4 or more colored bands or dots. The colors encode the first and second most significant digits of the value, and the third color the decimal multiplier in picofarads. Additional bands have meanings which may vary from one type to another.
Those capacitors having capacitance of 1000pf or more, their values can be read by the 3 digits numbers (e.g. 102. 103, 105 etc.) printed on it. These 3 digits color coding can be read as follows. Generally, the overall rating is written and printed on these capacitors. For example The fig 2 (a) The value of capacitance is 47 μF (microfarad).
Read the capacitance value. Most large capacitors have a capacitance value written on the side. Slight variations are common, so look for the value that most closely matches the units above. You may need to adjust for the following: Ignore capital letters in the units. For example, "MF" is just a variation on "mf."
Some capacitors have voltages represented in codes instead of value. Tolerance value is indicated using % symbol before the number. Tolerance value represents the variation of capacitance value . Ceramic capacitors have very small area to print the value of capacitance. So capacitance on these capacitors is represented using short hand notation.
Know the units of measurement. The base unit of capacitance is the farad (F). This value is much too large for ordinary circuits, so household capacitors are labeled with one of the following units: 1 µF, uF, or mF = 1 microfarad = 10 -6 farads. (Careful — in other contexts, mF is the official abbreviation for millifarads, or 10 -3 farads.)
The "+" sign in the symbol indicates the location of the capacitor’s anode. With this marking, we can deduce that the other side of the capacitor holds the cathode (negative pin), and hence no further marking, i.e. minus sign, is needed.
