The above image shows a Mylar film capacitor. The top "683" marking indicates the capacitance value, which is 68,000 picofarads (pF). To get this value, you multiply the leading digits (68 in this case) by 10 raised to the power of the last digit (3), and the result is the capacitance in picofarads (in this case, we get 68×10 3 pF).
In summary, the capacitor symbols are imperative in reading electrical schematics where the capacitors are correctly installed in the circuits. Capacitors can be categorized as fixed, variable, polarized, non-polarized, and specialized capacitors. Each one of these is uniquely identified with a symbol that denotes its characteristics and ...
