[Amps] Johnson 154-3 variable breakdown voltage?

[N7KA at comcast.net]

Johnson was picked up by Cardwell

In CARDWELL catalog p/n 154-3-1 (Johnson p/n was 154-3) (single section):  Peak withstanding voltage is 2000, 488-19pf.  Its about 5 inches between front and rear mounting holes.  If this sounds about right then not good for 2700VDC.
