I probably won't be able to identify it, but including the name of the thing it's a part of along with a model number would help.

SMT Capacitor

See the thick traces?

It's part of the power-section, which helps narrow-it-down, some..

Solid state relay? With like a heat sink on top?

I think it's some type of MLCC. If you look up variations of this inverter board, some have two MLCCs in the same location labeled C7 and C8. I know that some MLCCs can fail catastrophically if they crack and short circuit, may be what happened to yours.

If it's part of an LC circuit the capacity and ESR will be important to match, but if it's only a filter capacitor, you can typically drop in a high value cap to replace it without worrying too much about matching the values. Of course you'll want it to be rated for the voltage and temp.

looks like a power inductor

@la508i found an image of a different version of the same product i think,it seems like this one has some red components that look like film capacitors in place of that blown smd thingpower-systems.de/fileadmin/Med…

Is it a 3-terminal device? You may have to desolder it to find out. That also lets you poke around with the insides (hollow? layers?)

Probably a capacitor, either 2 terminal or 3 terminal. I was originally thinking GDT but it looks like even the SMD varieties are mostly cylindrical shaped rather than rectangular prism.

I think this is some sort of surface mount fuse.

Don't quote me on that as fact though.

Looks kinda like an un-encapsulated, surface-mount polyester capacitor e.g. https://dir.indiamart.com/items/kemet-f161zs104k630v-polyester-film-capacitor-surface-mount-s98697.html

They don't generally explode like that though unless they see overvoltage.
