A bag of 100 nF ceramic caps arrived from across the continent (“US Stock”) and failed incoming inspection:
Mislabeled 100 nF ceramic capacitor – actual 50 nF
The capacitor mark says 104, which is what you’d expect on a 100 nF cap, but the first half-dozen out of the bag measured around 55 nF, far outside even the loosest -20%/+50% tolerance.
Stipulated: the factory can ship every capacitor it makes with a proper mark.
Given their (lack of) provenance, they could be mis-marked 47 nF caps.
Somewhat to my surprise, a refund occurred instantly after I reported the problem.
Trust, but verify.
