Passive components (capacitors, inductors, resistors) are the "cornerstone" of electronic circuits, responsible for core functions such as energy storage, filtering, and current limiting. From smartphones to new energy vehicles, from 5G base stations to aerospace equipment, almost all electronic devices rely on them. The industry is characterized by high barriers to entry (dependence on material formulas, precision processes, and equipment), strong cyclicality (price fluctuations caused by supply-demand mismatches), and long-term growth potential (driven by demand in emerging fields). In recent years, it has shown a new competitive landscape amid technological iteration and domestic substitution.

I. Industry Overview: Cyclical Fluctuations and Growth Logic

Core Characteristics

• High Barriers to Entry: The performance of passive components depends on the ultimate refinement of materials and processes. For example, the dielectric material formula of MLCC (multi-layer ceramic capacitors) is a core secret of manufacturers; companies like Murata and Samsung Electro-Mechanics achieve a ceramic powder purity of 99.99%. For inductors, magnetic core materials need to balance permeability and loss, with TDK’s nanocrystalline alloy magnetic core technology leading the world. Additionally, production equipment (such as MLCC laminators and inductor winding machines) mostly relies on high-end equipment suppliers like Japan’s Disco and Germany’s Buhler, making it difficult for new entrants to break through in the short term.

• Strong Cyclicality: Industry supply and demand directly affect prices and production capacity. From 2017 to 2018, the surge in demand for smartphones and automotive electronics pushed MLCC prices up by over 300%. In 2019, the industry entered a destocking cycle, with some product prices halved. Since the second half of 2020, the popularization of 5G (a single base station uses 3x more MLCC than 4G), automotive electronics (new energy vehicles use 2-3x more passive components than traditional vehicles), and the surge in demand for remote office equipment post-pandemic have driven the industry into a new boom cycle. Lead times for some automotive-grade products have extended to over 6 months.

• Long-Term Growth Potential: The rise of new energy (photovoltaic inverters, energy storage systems), AI servers (each requiring thousands of MLCCs), and autonomous driving (lidar requiring high-precision inductors) has brought incremental demand for passive components. According to Yole, the global passive components market will exceed $300 billion by 2025, with a compound annual growth rate of 6.8%.

II. Global Leading Manufacturers: Regional Advantages and Core Competitiveness

1. Japan: Technological Dominance, Monopolizing High-End Markets

Japanese manufacturers, with centuries of technological accumulation, dominate high-end markets, especially in automotive-grade and military-grade high-reliability sectors, where they hold almost monopolistic positions.

2. South Korea: Focus on MLCC, Dominated by Samsung Electro-Mechanics

South Korean manufacturers, centered on Samsung Electro-Mechanics, focus on the MLCC sector and seize automotive and consumer electronics markets through differentiated technologies.

Samsung Electro-Mechanics: 2nd in global MLCC (21% market share). Its flexible electrode technology reduces electrode breakage caused by vehicle vibrations. Its automotive-grade products have passed AEC-Q200 certification and are supplied to BMW, Volkswagen, etc. In consumer electronics, it supplies 0201-sized MLCC to Apple’s iPhone with annual shipments exceeding 50 billion units. In 2023, it invested 1.2 trillion won to expand its Pyeongtaek factory, targeting monthly MLCC production capacity of 100 billion units by 2025.

3. Taiwan, China: Scale Integration, Building Full-Category Platforms

Taiwanese manufacturers expand rapidly through mergers and acquisitions. Led by Yageo, they build full-category capabilities covering "resistors + capacitors + inductors" to seize mid-to-high-end markets.

• Yageo: Global leader in resistors (25% market share) + 3rd in MLCC (12%). After acquiring KEMET (3rd in global film capacitors) in 2020, its revenue share in the new energy sector increased from 15% to 30%. In 2023, it merged Chilisin (5th in global inductors, 13% market share), becoming the world’s only manufacturer covering all three passive components, with total monthly production capacity exceeding 200 billion units.

• Walsin Technology: A multi-category supplier of MLCC and resistors, with 6 factories in mainland China (mainly in Jiangsu and Guangdong). It focuses on the mid-end consumer electronics market, supplying 0402-sized MLCC to Xiaomi and OPPO. In 2024, it started building a factory in Vietnam to avoid geopolitical risks.

4. Mainland China: Pioneers of Domestic Substitution, Achieving Breakthroughs in Clusters

Mainland manufacturers start from mid-to-low-end markets, gain a foothold in consumer electronics, and then penetrate high-value-added fields such as automotive and military, forming a "multi-point breakthrough" pattern.

III. Competitive Landscape in Segmented Fields: Concentration and Domestic Opportunities

1. MLCC: Dominated by Japan and South Korea, Domestic Brands Penetrating High-End Markets

• Global Pattern: Murata (31%), Samsung Electro-Mechanics (21%), and Taiyo Yuden (10%) account for 62% of the market, monopolizing miniaturized (below 0201) and high-voltage (above 500V) automotive-grade products.
• Domestic Progress: Fenghua Advanced Technology holds 15% market share in medium-to-large sizes (0603-1210). Micro One Electronics’ mass production of 01005 MLCC broke the monopoly of Japan and South Korea. Torch Electron’s military-grade products match Kyocera in performance.

2. Inductors: High Technical Barriers in Japan, Sunlord Electronics Breaking Through

• Leading Players: TDK (20%), Murata (13%), Taiyo Yuden (13%), Chilisin (13%), Sunlord Electronics (7%).
• Competition Focus: Automotive-grade inductors must pass rigorous temperature cycling (-40℃ to 125℃, 1,000 cycles) and vibration tests. Japanese manufacturers require a 3-year certification cycle. In 2023, Sunlord Electronics obtained Volkswagen Group certification, becoming the first domestic manufacturer to break into the high-end automotive market.

3. Resistors: Dominated by Yageo, Mainland Manufacturers Seizing Mid-to-Low End

• Market Distribution: Yageo (25%), Walsin Technology (12%), Japan’s KOA (10%), Rohm (8%). Fenghua Advanced Technology holds 18% market share in thick-film resistors for consumer electronics, with prices 10-15% lower than Taiwanese brands.
