Shielded metal-oxide-metal (MOM) capacitor structure
Two capacitor structures that are widely used for such circuits are the metal-insulator-metal (MIM) capacitor and the metal-oxide-metal (MOM) capacitor. Generally, MIM capacitors include an insulator sandwiched between two layers of metals while MOM capacitors are composed of a large number of parallel "fingers" or electrodes formed on numerous metal …
Regenerative Hull Tissue vs. Shield Capacitors : r/Stellaris
I tend to go shield-heavy. Disregarding bonuses against armor/shield, you can always get more total hit points out of shields due to capacitors and dark matter deflectors. That said, kinetic artillery is probably the most spammed non-explosive weapon in the game. I ...
