Capacitor codes: Difference between revisions

As small general purpose capacitors values range from a few pF to less than 1 µF the convention arose that whole numbers designate values in picofarads while decimal fractions designates values in microfarads. Any capacitor with a value of 1 µF or above is large enough to be marked with its actual value. A newer way to mark values is with three numbers on the body of the capacitor. Thewith the value is in picofarads,. The first two digits are the significant figures and the third digitthe ismultiplier a(i.e. multipliernumber of zeros). So for example 151 indicates a capacitance of 150 pF.<ref>[https://web.archive.org/web/20120814104332/http://www.play-hookey.com:80/dc_theory/capacitor_values.html Reading Capacitance Values] by Ken Bigelow</ref>
