I have what appears to be a capacitor. So my question 1 is whether it is or not a capacitor. Question 2 is if it doesn't have a + or - then I will assume it's not polarized. Question 3 is How can I tell what voltage was being applied? (VOM?)

I'll try and explain the size it's rectangle in size 1 1/8' long 3/4' high and 3/8' deep. The bottom looks like it's silicon filled (shinny). It was on a circuit board which was used for an a/c pump. The pin broke off so I need to solder on a new one.
I'm waiting for a meter which I ordered on line to measure and make sure it's a capacitor but I'm pretty sure it is.

Here is what I can make out reading the top of the capacitor :
I'm assuming the top row is the model # but I can't find it anywhere !

2u2 K 400 U7
Thanks for any help you can give me...Joey

This was neither feedback nor a suggestion, so I have moved it to a more appropriate forum.

 

Sounds like a polypropylene film cap. 2.2uF 400V, the K may be Kemet brand?

 

I agree that it is probably a 2.2uF 400V capacitor. Capacitor markings have a long, interesting, and rather perverted history, so it is hard to guess what the K and U7 might be. They might indicate manufacturer or they might indicate temperature coefficient or some other grading.

A quick search leads me to believe that the K might mean a 10% tolerance. But I'm far from certain of that.
