Identifying a cap...
2 Attachment(s)
I have a bunch of these caps...Mil surplus.

The package says 'ceramic', but I suspect that that simply refers to the outer casing. They measure 1f (and are marked '105') and the Mil part number suggests a 100V rating, but these would be the smallest 1f non-electrolytic I've ever seen. They are way too small and thin to be of ceramic conctruction...about the size of a 220pf ceramic cap.

Any idea of what they are? Stacked film? Or is there a stacked form of ceramic that could achieve this capacitance in this small a form-factor?

I seldom see ceramics at 1uF,they look like polyester to me.

If the Mil Number is : (or what is the mil # )
CK05 0r CK06 XX 105 they are considered monolytic caps
very close to a ceramic.. 105 for sure is a 1 Uf
Letter afterwards is the percentage J = 5% K = 10%
M =20% HTH's

Here's what it says on the package:

2N335      RPE114Z5U105M100V
Case/MFG  051406  PN/MFG  Same
Capacitor, Fixed, Cer
1 EA
A/C    09/94

Odd parts for sure.

105M100V I think the last part may just be the answer with 105 being normal capacitor rating marking and 100V limit.
It is small but I got smaller ones...
