Most capacitors have numbers printed on their bodies to indicate their electrical characteristics. Larger capacitors like electrolytics usually <answer>display the actual capacitance together with the unit (for example, 220 μF)</answer>. 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 × 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?
display the actual capacitance together with the unit (for example, 220 μF)
