NF 925
nickel filled
not sure about the NF but 925 is silver i know that much for sure!!
"Now or Formerly"
Depending on context, NF-3 could be neurofibromatosis type 3 or Nitrogen trifluouride.
I can answer part of this, if it is the artist I knew
(Cwe) Charles winston edition (cz)cubic zirconium (925) sterling silver (nf) nickel free..
"925" means it is sterling silver or a 92.5% purity of silver. NF is a hallmark of the silversmith. I am trying to find nf now. I will post when I find it. From LCsocal: I am not sure that is correct, otherwise NF would be the busiest man in Thailand. I believe the "NF" indicates "nickel filled" with sterling silver plating. This would be consistent with the hallmark GF 14K, which means gold filled--an alloy of some sort with 14K plating. You'll note that the silver pieces from Thailand with the NF 925 hallmark are usually exceptionally well priced and this explains why. I am certain that the NF stands for nickel free as there are many who are not able to have nickel in there jewelry as they are allergic to it, and as the sliver has alloys added to it, the other .75 of the 9.25 as it is a make up of other metals to make it hard and useable for things like jewelry.
no two cases of nf are the same There are 3 types of NF. Nf 1 nf 2 and Schwannomatosis NF can cause learning disables and Hearning problems NF is usually inherited but can also occur with no family history It is rumored that Abraham Lincoln had NF and was partly gay

While it is possible that the company producing the capacitor is using the NF as an identification tool, usually we would expect nF to specify the capacitance or value of the capacitor. For example, a capacitor with the value of 10nF ought to have a capacitance of about 10 nano Farads. This is equivalent to 10*10-9 Farads.
