![]() Resistor color codes- how to calculate resistor ceramic capacitor value. Component resistance colour code chart resistor color codes of resistors pdf images download thumbnail. A 220nF electrolytic capacitor will be labeled as 0.22♟ and not 220nF). Electrolytic capacitors are pretty simple to read: as they are quite big compared to the rest, the value is directly written in the enclosure.The value unit is also specified, but as they have large capacitance values the chosen unit is the microFarad (♟) almost 100% of the time, even when the unit is smaller (i.e. (See chart above for tolerance color codes.). The fifth dot will indicate the tolerance. In either case, read the capacitance in picofarads from the next three color dots. The first dot on a mica capacitor is White to indicate EIA six dot code.
