Multilayer ceramic capacitors are essential passive components in high-frequency electronic systems, where they must satisfy demanding and often conflicting requirements for volumetric efficiency, temperature stability, low dielectric loss, and long-term reliability. Traditional materials development in this domain has relied on empirical formulation and processing iteration, which is slow, costly, and difficult to reproduce across manufacturing environments. This paper examines how artificial intelligence can accelerate the optimization of dielectric ceramics, electrode compatibility, and multilayer architectures. It presents a system-level perspective that integrates high-throughput experimentation, materials informatics, active learning, and uncertainty-aware model deployment. The discussion emphasizes structural trade-offs among dielectric constant, loss tangent, grain size, layer thickness, and high-frequency parasitic effects. Rather than focusing narrowly on predictive accuracy, the paper addresses architectural requirements for data infrastructure, ontology design, feature engineering, and workflow orchestration in industrial and research settings. It further considers deployment challenges such as distribution shift, model robustness, qualification constraints, and human oversight. Governance, fairness, sustainability, and policy implications are analyzed in the context of critical materials supply chains, reproducibility, and global research equity. The paper argues that effective AI-driven optimization of multilayer ceramic capacitors requires an integrated socio-technical system in which machine learning models, experimental platforms, manufacturing data, and regulatory frameworks co-evolve. Aqueous tape casting progress for ultrathin barium titanate films illustrates the importance of process-level innovation in expanding the design space. The findings provide a forward-looking framework for researchers, process engineers, and policymakers seeking to align computational acceleration with responsible and scalable materials manufacturing.
