Title: Unusual capacitor values
Post by: jada3909 on September 27, 2023, 12:58:26 pm

Hello,
I'm dealing with an old schematic that shows capacitor values unlike I've ever seen before. For example:
005 MFD
I get the MFD part but there is no decimal point shown. Could it be 0.005uF? Has anyone dealt with this in an old schematic?
Thank you!

Yes.

If you can't find a reasonable replacement cap, .0047uF are easily available and likely within spec of the older .005uF (which were often +/- 10-20%).
