I did not know about this mounting method. Probably it's a way to improve passive cooling capabilities?
That's an airburst capacitor!

Nice! Could you explain what it is or where to find more information about it? I was not able to find information online
... I'm sorry to say that was a joke, because well, capacitors like to go boom (MLCCs as in here not so much, but still).
What I do know though is that these MLCCs often dramatically change their actual capacitance with temperature, so maybe this is a sort of "temperature isolation" to keep the capacitor more stable? Honestly, no idea though.
I’d say that’s a version of a soft termination capacitor. They are used when there’s risk the board is flexed or exposed to mechanical or thermal shocks to prevent cracks in the capacitor (causing it to fail short).
Do you have more information on this? I'm working on a PCB that suffered from a broken ferrite due to flex.
They are called soft termination, I’m not sure if that’s available for every component, it came to my attention on ceramic caps. It’s a dedicated feature you can filter components e.g. on Digikey.
