odd high voltage capacitor

[alwayslearning]

having a lot of trouble finding info on this little bugga .
N3
3kv
SEC
i know 3kv is the voltage but N3 and SEC are the puzzle .
its from a compaq monitor and have been looking for hours for a definite rating on this .

[Psi]

They're part of the backlight circuit,

Search for service manuals and schematics for any similar compaq monitor. It should have the value/spec listed in the schematic.

Its pretty likely that all similar sized monitors from compaq use the same value for this cap

Suppose it said 3N3, what would it be? Just like a 4R7 resistor.  I have trouble getting used to it too.

No able to do more research at this time, but check out page 5:

My best guess is that the N means nanofarad, and that it means it's of 0.3nf capacitance.
A capacitance meter would probably give you the best answer though (provided the cap itself is good)
And if you got more than one of these caps on there, you could measure those too just for confirmation.

google search "N3 3KV SEC",

I found this on Taobao
"N3 3KV 8NPO3R0D302H76E"
https://item.taobao.com/item.htm?spm=a230r.1.14.141.uq9uCP&id=541940694955&ns=1&abbucket=18#detail

SEC is the Taiwan's Sucecess Electronics Co. Ltd
http://www.cc-sec.com/eindex.asp

the Order Part Number "8NPO3R0D302H76E" means DC Epoxy Coated, NPO, 3pF, 3kV

N doesn't seems to be a Unit, I think N is Letter Code for temperature coefficient (+/- 2500)

Ceramic capacitor
Class 1-ceramic capacitors
letter codes for temperature coefficients ? referring to EIA-RS-198
