We use nanoFarads as a standard prefix at my shop and most of my=20 local contemporaries do the same. 1n0, 10n, 100n are values shown on the schematics and in the PCB Bill=20 Of Materials documents. And all the values in-between those: 2n2, 3n3, 4n7= .. For what it's worth, I keep in stock small to medium value capacitors=20 - both in ceramic (monocap) and in film - capacitors with values of=20 1n0, 2n2, 3n3, 4n7 all the way up to 220n. Although I still do have=20 some capacitors in the E12 values, I've tried hard over the years to=20 stay with those 4 values per decade. Seems to work out, for the most part. dwayne At 09:35 PM 1/29/2016, Adam Field wrote: >Content-Transfer-Encoding: base64I work at one of the larger=20 >capacitor manufacturers and this thread makes >me laugh.
