Vertical carbon nanofiber capacitors in package substrates raise capacitance density while lowering ESR, power loss, and internal heating.
A metallic heat sink plate placed between the capacitor and circuit board blocks electromagnetic noise, prevents malfunctions, and improves cooling.
Multiple passive tiers linked by TSVs add ESD protection, adjustable thickness, and higher capacitance or inductance in the same footprint.
Placing Y capacitors and the ground bus bar within the PN region cuts capacitor module height while preserving noise absorption and smoothing.
Photosensitive glass-ceramic processing forms high-aspect-ratio 3D capacitor textures with lower cost, better yield, and higher capacitance.
A transverse busbar rail layout cuts stray inductance, shields high-frequency fields, and improves cooling around converter power units.
Triangular-pyramid corner electrodes let multilayer ceramic capacitors pack multiple unit capacitors into less board area while avoiding shorts.
Elastic connecting protrusions clear the insertion path between busbars, improving capacitor element assembly and soldering quality.
