Usually the first two digits of the code represent part of the value the third digit corresponds to the number of zeros to be added to the first two digits. The codes below are generally found on ceramic (little round discs) and mylar (chicklet) capacitors, which are not polarized, that is, there are no positive and negative leads. BEAM circuits are often bilateral (two-sided) and balanced, and in these cases try to use the same value on both sides. You can generally substitute one of these for a single cap in a given circuit. However, you might occasionally find an unusual value such as 0.15 or 0.27. MF = microFarad (not milliFarad as you'd expect) 1 F = 1 000 000 000 000 pFĬapacitor values are usually standardized-.10.22. UF = microFarad (the letter u substitutes for the Greek letter micron) 1 F = 1 000 000 uF

PF = picoFarad, 10 -12 farad (that's one trillionth!) 1 uF = 1 000 000 pF

001uF and 47uF for timing, signal conditioning, and power filtering and between 1000uF and 1F for storage in solar engines.

BEAM projects typically use caps between.

The Farad is a HUGE quantity, and most capacitors are only a fraction of a Farad.Named in honor of scientist Michael Faraday, a pioneer in electronics.A Farad is the measure of electronic capacitance.Now I have a DMM that reads capacitance, which makes identifying capacitors much simpler. Finally it occurred to me to do up this chart. When I first started doing electronics, capacitors ('caps') were a real puzzle, and I often just substituted them in a breadboarded circuit until I found one that worked.
