Specializing in high-end connectors for 30 years, JONHON’s products are widely used in aerospace (exclusive connector supplier for the C919 airliner), rail transit (supplying 60% of localized connectors for Fuxing high-speed trains), and industrial control. With 15.8 billion yuan in revenue in 2022, it has achieved remarkable results in converting military technologies to civilian use: its new energy vehicle battery swap connectors support a high current of 1000A, and its industrial 5G connectors meet IP69K protection standards. It is one of the few domestic manufacturers certified to the IATF 16949 automotive standard.
A global leader in micro-electroacoustic devices, AAC holds 28% of the global market share for MEMS microphones (a key supplier to Apple and Samsung) and its haptic feedback motors cover 60% of high-end smartphones worldwide. In 2023, it entered the automotive electronics sector, developing in-vehicle microphone arrays integrated with active noise cancellation technology for BMW. Its Changzhou factory has built China’s first automotive-grade electroacoustic component production line, with an annual capacity of 120 million units.
China’s only leading passive component enterprise with a full "material-device-module" industrial chain, Fenghua has an annual production capacity of 100 billion Multi-layer Ceramic Capacitors (MLCCs), with a yield rate of over 98% for ultra-miniature 01005-sized MLCCs. In 2024, it mass-produced automotive-grade AEC-Q200 MLCCs, breaking the monopoly of Murata and Samsung. The new energy battery BMS capacitor module co-developed with BYD can withstand temperatures up to 150°C and has a service life of over 10 years.
A benchmark in the aluminum electrolytic capacitor industry, Jianghai independently developed "ultra-high voltage etched foil" technology, breaking the 500V voltage resistance bottleneck. It holds the top domestic market share for new energy vehicle DC-Link capacitors (supporting CATL and Huawei electric drives). In 2023, it acquired part of the production lines of Japan’s NCC, integrating NCC’s winding technology. It has mass-produced long-life capacitors (100,000 hours) for industrial inverters, which have entered the supply chains of Siemens and ABB.
Ranked among the top 3 globally in chip inductors, Sunlord holds 45% of the market share for ultra-small 0201-sized inductors. Its 5G RF inductors are used in flagship models of Huawei and OPPO. In 2024, its Huizhou factory put into operation an LTCC (Low-Temperature Co-fired Ceramic) production line, mass-producing high-Q filters for 5G base stations and breaking the technological blockade of Murata and TDK. It is the only domestic manufacturer with the capability to supply full-band 5G RF components.
A leader in automotive-grade Insulated Gate Bipolar Transistors (IGBTs), BYD Semiconductor independently developed 7th-generation IGBT chips, breaking Infineon’s monopoly. These chips are integrated into BYD’s Blade Battery systems, reducing switching losses by 20%. In 2024, its production capacity reached 240,000 wafers per month. In addition to supplying BYD’s own needs, it also provides on-board BMS chips to NIO and XPeng, and holds the top domestic market share for automotive-grade MOSFETs.
The "king of display panel components," BOE had an annual production capacity of 150 million flexible AMOLED screens in 2024—one out of every 4 foldable smartphones globally uses a BOE screen. Its Hefei 10.5th-generation production line mass-produces 8K Mini LED backlight modules, and its self-developed LTPO adaptive refresh rate technology is applied to Huawei’s Mate series. BOE ranks 2nd globally in automotive display panels (supplying Mercedes-Benz and Volkswagen).
9. YOFC (Yangtze Optical Fibre and Cable Joint Stock Limited Company)
A "national team" in optical communication devices, YOFC masters the core technology of G.654.E ultra-bend-resistant optical fibers and holds the top domestic market share for 5G fronthaul optical modules. In 2023, it acquired Broadex Technologies, integrating PLC optical splitter technology. Its products have entered the backbone networks of AT&T and Verizon, and it ranks among the top 3 globally in submarine optical cables, supporting 80% of domestic data center optical interconnection construction.
A dual champion in MEMS sensors, Goertek holds 70% of the global market share for VR/AR optical modules (a key supplier for Meta’s Quest series). Its self-developed 6-axis inertial measurement units (IMUs) have an accuracy of 0.01°/h, enabling it to enter the industrial robot sector. In 2024, its Qingdao factory mass-produced automotive-grade pressure sensors, breaking the monopoly of Bosch and Honeywell, and now serves over 20 domestic new energy vehicle manufacturers.
These enterprises, spanning from connectors to semiconductors, have broken technical barriers in various segments, moving from "scale advantages" to "technological definition power." They reshape the global electronic component landscape, injecting core impetus into China's electronic industry's leap toward high-end sectors.
