Capacitor Codes


Mica Capacitors


Colour Code

The first dot on a mica capacitor is White to indicate EIA six dot code. It may also be Black for military code. In either case, read the capacitance in picofarads from the next three color dots. The fifth dot will indicate the tolerance. (See chart above for tolerance color codes.) The sixth dot indicates classes A to E of leakage and temperature coefficients,. The maximum rating for DC working voltage is generally 500 V.
