Having looked at the data sheets I am a bit confused as to how to correctly connect these in a power supply. I am using 30 uf 700 volt with 4 pins. Which pins connect to ground and which to the high voltage? Some of you may know that the cap is oblong with 2 pins at each end. So do the 2 pins along the long side form one connection, or is it the 2 pins at the narrow end that form a connection. Hope I have been clear in my description😱 May just go back to conventional electrolytics as these are bulky with no obvious way of mounting them🙁
The two terminals at each end are connected together internally. It's like a Kelvin connection.
Mounting is on a pcb.

Kelvin connection?
Your description matched how I understood how to connect them from the data sheet. I don't understand what a Kelvin connection is, could you elaborate? Thanks🙂

A Kelvin connection minimizes any interaction or noise coupling between the input and the output circuits
due to the part's lead resistance and inductance. Sort of like star grounding, but for both ends of the part.

I have the 900 volt version in the parts box and Rayma is correct, the terminals at the end are connected. You'll see a <1 ohm resistance between them if you measure it, and a very high (or open circuit) between the ends
