The rapid expansion of artificial intelligence (AI) infrastructure is creating significant changes across the electronic components market, particularly for multilayer ceramic capacitors (MLCCs). As data centres scale up to support increasingly powerful AI systems, demand for these critical passive components is growing at an unprecedented rate, placing new pressures on global supply chains.
AI Servers Driving Higher MLCC Demand
One of the biggest changes in AI server design is the shift from traditional 12V power architectures to more efficient 48V systems. Higher-voltage power distribution reduces energy losses and improves overall efficiency, while advanced technologies such as LLC resonant converters and emerging 800V power architectures are helping data centres handle ever-increasing power demands.
These developments are dramatically increasing the number of capacitors required in server platforms. Industry estimates suggest that AI servers can use between 10 and 15 times more MLCCs than conventional server designs. At the same time, demand is shifting toward higher-capacitance and higher-voltage components, which require more advanced manufacturing processes and tighter production tolerances.
Production of MLCCs remains concentrated among a relatively small number of global manufacturers, including Murata, TDK, Kyocera AVX, Taiyo Yuden, Samsung Electro-Mechanics and Yageo. To meet booming AI-related demand, many of these suppliers have prioritised capacity for high-performance applications, reducing flexibility in the supply of standard components used across consumer, industrial and automotive sectors.
Growing Supply and Pricing Pressures
As manufacturers redirect production toward AI infrastructure, concerns are growing over the availability of high-capacitance MLCCs. Distributors and market analysts are increasingly warning of tighter supply conditions, drawing comparisons with the component shortages experienced across the electronics industry in 2021.
The market is becoming increasingly divided between strong AI-driven demand and softer conditions in traditional consumer electronics sectors. At the same time, rising raw material, energy and transport costs continue to create uncertainty throughout the supply chain.
Materials commonly used in capacitor manufacturing, including silver, copper and aluminium, have all experienced price increases, contributing to average passive component cost rises of around 10-15%. In response, OEMs and distributors have adopted more proactive inventory strategies, securing stock earlier to minimise exposure to future shortages and price increases.
Pricing pressure is already becoming visible. In 2026, several suppliers began introducing selective MLCC price increases, signalling the potential start of a broader market recovery after an extended period of softer demand. Many manufacturers are now monitoring supplier negotiations closely to assess whether price rises will spread further across consumer and automotive product ranges.
Long-Term Growth Remains Strong
Despite short-term supply challenges, the long-term outlook for the MLCC market remains highly positive. Continued growth in AI computing, 5G infrastructure, electric vehicles and industrial automation is expected to drive sustained demand for compact, high-performance capacitors.
Manufacturers are investing heavily in new technologies, including ultra-thin dielectric layer designs that enable higher capacitance, improved reliability and smaller component footprints. At the same time, volatility in key materials such as nickel and palladium is encouraging investment in recycling programmes, alternative materials and more efficient production techniques to strengthen long-term supply resilience.
While Asia-Pacific continues to dominate global MLCC manufacturing, near-shoring strategies and government-backed technology initiatives are encouraging additional investment closer to major end markets, helping improve supply chain security for the future.
