it is a 1nF capacitor. Probably 50V or thereabouts.

thanks! i hooked it up to my multimeters capacitance reader and is said .9 nf earlier i just didn't trust it. thanks alot for the conformation!!!

i couldnt find anything on the net with e5k 102. is that even a part number or value? how can a read for next time i see something like this?

no problems.

the markings indicate the capacitance, but experience is what tells you it's a capacitor.

102 means 10 x 10^2 pF.
1000 pF is 1 nF which is also 0.001 uF

A marking of 473 would be 47 x 10^3 pF or 47nF

thanks makes a lot of sense does the e5k mean anything?

oh, and e5k tells you other details about the cap.

K is often used to mean 10% tolerance, and 5 is likely related to the voltage rating. I don't believe it would be 5V, so I guess that it would be 50 based on its side and my experience.

for more information you would need to find the datasheet for the cap. Without knowing the manufacturer of the series, that's not trivial.

Steve,
It is indeed a 50V cap.
The voltage(code and location) is probably the only common parameter to various manufactures.

The first letter is the manufacture id.
,the last can be dielectric type.
See an example from "Kemet"
