0.01UF 50V ZF - What does ZF mean?
« on: November 02, 2011, 05:18:51 am »
I need to replace a few caps on a receiver and the service manual species the following:

0.01UF 50V ZF
0.1UF 50V ZF

What does the ZF stand for?

I think it maybe another way of saying the temperature coefficient of Z5V

There 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-CONTENTS

Also this table seems to back that up. It looks like there are three naming schemes  EIA / JIS / GB


It 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

It means it should be a 105 oC rated capacitor.

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

Yes, even better than manufacturer reccomended specs

Do 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.

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

Does Nichicon even make ceramic caps? How about a link?

Im not sure how you know does authur means exactly ceramic capacitor, but if you checked their website you could see they dont make only electrolytic capacitors.

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.
