Variable capacitors are labeled with numbers or alphanumeric codes to indicate their capacitance value, rated voltage, tolerance, and temperature coefficient. Some capacitors use a 3-digit notation, where the first two digits represent the capacitance value and the third digit indicates the multiplier or the number of zeros after the second digit.
But the confusion comes in when you consider the millifarad units that could also stand in as mfd. Millifarads are of a more excellent order than the microfarad units. The older capacitor manufacturers often represent microfarads as MFD, which was the standard back then. Today, most manufacturers prefer to use uF to represent …

Model of a capacitor. A capacitor (historically known as a "condenser") is a device that stores energy in an electric field, by accumulating an internal imbalance of electric charge. It is made of two conductors separated by a dielectric (insulator). Using the same analogy of water flowing through a pipe, a capacitor can be thought of as a tank ...
