Those things are useful for those of us who like to play with actual high
voltage.  You know, like 10kV and up!

That item is almost certainly a trigger device.  Looks like an SCR or
something, marked 12V on the end with small coils in the clear plastic
underneath is.  Those caps can start your heart, but they can also stop
it!  It probably has an internal resistor or one across the terminals to
discharge it when not in use.  The ones in microwave ovens have had them
for some time.
