Introduction

As the "rice of the electronics industry", MLCC is an indispensable basic component for all electronic products, with global annual demand exceeding 5 trillion units. For a long time, the global MLCC market has been monopolized by international giants such as Murata (Japan), Samsung Electro-Mechanics, and TDK, holding over 90% of the high-end market share. In recent years, intensified global geopolitical conflicts and increased supply chain uncertainty have led to frequent supply disruptions, price hikes, and extended lead times from international manufacturers, seriously threatening the security and development of China's electronic information industry. MLCC domestic substitution has transformed from an "option" to a "necessity", becoming a national strategy and industry consensus.

After more than 20 years of development, China's MLCC industry has made considerable progress, forming a complete industrial chain from materials and equipment to manufacturing and applications. Domestic MLCC has achieved large-scale substitution in the consumer electronics field and made breakthroughs in mid-to-high-end fields such as industrial control, automotive electronics, new energy, and communications. However, there are still certain gaps between domestic MLCC and international giants in high-end technology, product reliability, consistency, and brand influence. The domestic substitution process faces many challenges such as difficult selection, long verification cycles, and unstable quality.

Based on the current development status of the global MLCC industry and combined with Barron MLCC technical team's years of practical experience in domestic substitution, this whitepaper systematically analyzes the global MLCC industry landscape and the urgency of domestic substitution, comprehensively demonstrates the technical status and breakthroughs of domestic MLCC, deeply dissects the advantages and disadvantages of the domestic MLCC industry chain, and provides standardized domestic substitution selection guidelines and verification processes. Covering full-scenario substitution solutions for consumer electronics, industrial control, automotive electronics, new energy, and communications, it proposes effective mitigation measures for common risks in the domestic substitution process, helping enterprises achieve safe, efficient, and low-cost MLCC domestic substitution and ensure supply chain security.
