3 legged dual capacitors? and what do you call those rectangular caps?

I salvaged 2 Furuno LC-90 Loran C units out of the dumpster at a wharf and it has these strange 3 kegged capacitors. The circuitboard labels them as TWO separate caps and the outside legs have ferrites over them.

What special purpose do these caps have?

They look just like this https://www.surplus-electronics-sales.com/images/products/120-1051 22pF 100V Dual Capacitor Y5S.jpg
except they're labeled D 223S


ALSO they have those long rectangular capacitors with exposed legs seemingly soldered directly to the ends labeled 1u5 100
What are those called?
They look allot like this but a bit bigger **broken link removed**

Foil Polyester I'm assuming according to the site where I found that photo?

The first "capacitor" is a low pass RFI filter. It is a capacitor with two beads, one on each wire. It forms a LC filter. See attached data sheet. Different company but you will get the idea.

Capacitor 2; probably is also used for removing radio frequency noise. Call it a capacitor. This one looks like it was made for a switching power supply. High voltage!

There are X and Y type capacitors. One type is specifically made to connect from line to ground and the other from line to line.
The pic you showed was a Y capacitor.

NO. The legged cap is marked 100 volt. A "X" and "Y" cap must be marked as such.

Debatable, a "Y" could be interpreted as a "V". I can't definitively tell if it is 100V or 100Y. I interpreted it as a Y.

I can't even make out the first line either.

Not sure if UL or CE labels are on them too.
