This is an inquiry of broader interest, as FCI is the manufacturer of the
.01 mfd, 100 kV caps sold by Fair Radio and used by a number of coilers
with good success. As far as I know, "FCI" has never been identified, and
the dielectric used in these caps (suspected to be Mylar) has never been
confirmed.

Anyone have any insight??

Hi all,
        Would someone help me please? I would like some data on a
capacitor with the following legends stamped on the case.

The case: blue plastic, axial leads, translucent end filler.

The legends exactly as they are stamped on the case:

          F-C-I
        KM9-125-2
   .002MFD- 12.5KVDC

        11M/81

The capacitance and working voltage is obvious. The last legend
implies a date of manufacture. These caps were wired in a series
string with a 1k composition resistor between each and a 200 MOhm
thin or thick film resistor bridging each. I know it was intended for
some kind of use in a 120kV supply which used a bundle of flyback
transformers. I also have two strings of the same type of cap rated
at 0.015uF at 15kVDC.

What kind of capacitor have I got?

Thanks in advance,
Malcolm
