Multilayer ceramic capacitors, essential for powering modern electronics, are experiencing unprecedented demand fueled by AI advancements, leading to supply bottlenecks and industry-wide production challenges.
- AI servers now require up to 28,000 MLCC units, over 13 times previous amounts
- Japanese and South Korean makers leading rapid capacity expansion efforts
- Raw material constraints and geopolitical tensions threaten supply chain stability
What happened
The soaring computational demands of artificial intelligence have led to a dramatic increase in the use of multilayer ceramic capacitors (MLCCs), crucial components in electronics ranging from smartphones to electric vehicles. Specifically, AI data centers and servers require far more MLCCs than traditional systems, with AI servers using up to 28,000 units—thirteen times more than usual. This surge is driven by the need to support power-hungry AI training and inference workloads, as seen in next-generation platforms like Nvidia’s Rubin architecture.
Beyond AI infrastructure, rising usage in autonomous vehicles, humanoid robots, and electric vehicles adds to the surge in MLCC consumption. The rapid growth in orders has extended lead times dramatically and forced major manufacturers, particularly Japanese and South Korean industry leaders, to prioritize high-end MLCC production, causing supply stress for consumer electronic components.
Why it matters
This supply bottleneck is significant because MLCCs are indispensable to a vast array of cutting-edge electronics. The inability to meet demand could hinder production timelines for smartphones, electric vehicles, and AI-enabled devices, potentially impacting innovation cycles in these sectors, especially within China’s technology market where AI adoption is rapidly expanding.
On the upstream side, critical raw materials such as nano-grade ceramic powders and specialized release films, required for manufacturing high-end MLCCs, are in limited supply. Geopolitical tensions have also caused spikes in the cost of raw materials like crude oil, which affects the pricing and availability of MLCC components. These vulnerabilities underscore the fragility of global electronics supply chains amid growing AI-driven demand.
What to watch next
Investors and industry watchers should monitor the progress of capacity expansion efforts by key MLCC manufacturers like Murata and Samsung Electro-Mechanics. Murata’s recent announcement of a $1.56 billion capital expenditure plan aims to increase server-grade MLCC production by over 20% in two years, although this may not fully satisfy the accelerating AI-driven demand. Samsung’s new plant in the Philippines also signals an aggressive push to enhance production capabilities.
Additionally, fluctuations in raw material markets and geopolitical developments could impact supply chain stability and component pricing. Any delays or disruptions in expanding production capacity or securing essential materials may extend MLCC lead times further, influencing technology product launches and AI infrastructure build-outs in China and globally.
