content: I think it maybe another way of saying the temperature coefficient of Z5VThere are some graphs here which have Z5V(ZF) Y5E(YA) Y5P(YB) Z5U(ZE)http://www.docstoc.com/docs/68640250/ARITEC-Ceramic-Capacitor-TABLE-OF-CONTENTSAlso this table seems to back that up. It looks like there are three naming schemes EIA / JIS / GBIt does seem odd though because Z5V isn't a high spec cap, far from it. It's pretty bad in fact.So why anyone would label something as needing to be that type of cap is a bit weird.I'm sure someone will know for sure what it means

content: It means it should be a 105 oC rated capacitor.

content: So if I order a 5% part @ 125C then I should be fine, right?

content: Quote from: hacklordsniper on November 02, 2011, 06:30:09 amDo you have a source? The PDF version of the document Psi linked to claims 10 to 85°C. Choosing an NP0 cap should work fine, but is probably much larger and more expensive than required for this application if Z5V is called for.

content: I was just planning on buying the 3 caps and 2 fusible resistors through digikey. Total cost is < $5.00. Not a big deal.

content: Have you seen any 10nF/50V electrolytics (aluminum, tantalum or conductive polymer) lately? It could be film, but this would be indicated as such, and Nichicon doesn't make any film caps with ZF in the name. Part number search for ZF yields no results. Psi's answer looks plausible to me without any proof to the contrary.
