I think it means 1µF 300VDC

The threaded end makes me think is a feedthrough capacitor. Measure the resistance (yes resistance, not capacitance) across the two ends. If it remains basically zero then it is a feedthrough type and the 1uF is between the conductor that runs from one end to the other and the case. It is used to filter RF from a signal passing to or from a shielding enclosure.

Casey knows his business.
I use such feedthrough filter caps on my cars, shaffner's.
Look identical, except for the brand.
Shaffner's are worth $0.50 here.
A lot of them are used in the telecom field.

Measurments

Pin1 2 Pin2 1uF/Open
Pin1 2 Case 0uF/Open
Pin2 2 Case 0uF/Open

The question is what type/material is it? Polyprop, PIO, Teflon?

 

[jacco vermeulen]

i am not an expert on Sprague, but my guess is that these caps do not differ that much between manufacturers.

A Siemens/Epcos feedthrough has a metalised polypropylene di-electric.
Such caps are made up till 4.7uF.
See www.epcos.com keyword B85121

Could also be oil impregnated paper.
