Capacitor Capacitor Capacitor Capacitor
Most capacitors have numbers printed on their bodies to indicate their electrical characteristics. Larger capacitors like electrolytics usually display the actual capacitance together with the unit (for example, 220 mF). Smaller capacitors like ceramics, however, use a shorthand consisting of three numeric digits and a letter, where the digits indicate the capacitance in pF (calculated as XY x 10Z for digits XYZ) and the letter indicates the tolerance (J, K or M for +-5%, +-10% and +-20% respectively).
How do larger capacitors present their electrical characteristics? What part of the electrical characteristics of smaller capacitors do the digits of the abbreviated notation represent ? What does the letter of the abbreviated notation for the electrical characteristics of smaller capacitors represent? In what SI unit is the capacitance reported on smaller capacitors?
