The electronic component sector is currently reaping structural industry dividends, with the AI computing power and humanoid robot tracks both undergoing simultaneous rapid expansion.
Expanding AI Server Hardware Unlocks New Growth Drivers for FOSAN Resistors
On one hand, investments in data center construction are ramping up nationwide, driving sustained rising demand for high-reliability components in AI servers and GPU power supplies. On the other hand, mass production and commercial rollout of humanoid robots and industrial automation equipment are accelerating, fueling steady growth in the market for industrial control matching resistors.
I. Explosive Demand Across Dual Tracks Opens a Window for Domestic Substitution of High-End Resistors
End devices operate under harsh working conditions, imposing strict mandatory requirements on resistors such as automotive-grade reliability and anti-sulfidation performance, pushing demand for high-end special resistors upward.In contrast, overseas passive component manufacturers are generally scaling back high-end production capacity, raising selling prices and extending delivery lead times, which amplifies risks of supply chain instability. Domestic resistor brands with independent R&D capabilities and comprehensive quality control systems have secured a rare opportunity for import substitution.
II. Key Industry Pain Points: Sulfidation Corrosion and Wide-Temperature Drift Undermine Equipment Stability
AI server rooms feature enclosed high-temperature environments, while industrial workshops contain dust mixed with sulfide gases. Conventional chip resistor electrodes are highly susceptible to erosion by sulfur ions, resulting in resistance drift and sampling failure after long-term operation, and even complete equipment shutdown in severe cases. Frequent start-stop cycles of robot servos generate continuous current surges, and standard components suffer significant parameter fluctuations under temperature variations, failing to meet control precision standards.To address these universal industry challenges, FOSAN has developed dedicated product lines including anti-sulfidation and automotive-grade resistors. Our anti-sulfidation resistors adopt multi-layer composite anti-corrosion coatings to isolate corrosive media. The full range of high-end products is developed in compliance with the AEC-Q200 automotive standard, undergoing thousands of high-low temperature cycling and damp-heat aging tests. They maintain stable parameters under heavy current surges while delivering core advantages of low temperature drift and high precision, suitable for long-term operation in all types of harsh environments.
IV. Independent R&D of Material & Process + Full Product Portfolio Cover All Circuits for Computing and Robotics
FOSAN has achieved independent breakthroughs in core materials and manufacturing processes. Our self-developed heat treatment technology for alloy materials delivers ultra-low temperature drift down to ±10ppm/°C. Paired with micron-level electron beam welding technology, the solder joints are dense and void-free, satisfying continuous high-current detection requirements of devices.All product lines hold IATF16949 automotive quality system certification, featuring minimal resistance fluctuation across wide temperature ranges and strong resistance to frequent instantaneous current surges. Meanwhile, FOSAN has built a comprehensive alloy resistor portfolio covering standard alloy resistors, bare chip alloy resistors, through-hole alloy resistors, alloy shunts and four-terminal resistors. We provide one-stop component solutions for all circuit scenarios, including VRM power supplies and busbar detection in AI servers, robot servo drives and outdoor industrial control boxes, cutting customers’ costs of coordinating multiple suppliers.
V. Four Intelligent Manufacturing Bases with Flexible Production Balance Lead Time and Mass Delivery
For production, FOSAN operates four smart manufacturing bases with dedicated flexible production lines for general resistors and special automotive-grade anti-sulfidation resistors, supported by large-scale intelligent warehouses maintaining two months of safety stock on hand.Lead time for regular orders is controlled within 30 days, while prototype samples for urgent customer demands can be delivered in as fast as 3 days, aligning with the rapid iteration pace of the AI and robotics sectors.We have established a closed-loop full-process quality control system covering IQC incoming inspection, IPQC in-process inspection, FQC semi-finished product testing and OQC outgoing inspection. Supported by a senior technical team with years of experience, we offer one-stop technical services including model selection matching and reliability testing, comprehensively lowering customers’ R&D and commissioning costs for complete equipment.
VI. Medium & Long-Term Capacity Expansion Plan Laid Out to Strive for Top Global Industry Ranking
Large-scale and stable production capacity is the cornerstone of long-term reliable supply. FOSAN has formulated a phased capacity expansion roadmap with clear targets:
Monthly capacity target of 35 billion pieces in 2026, with production capacity prioritized for high-end automotive-grade and anti-sulfidation resistors;
Monthly capacity expansion to 50 billion pieces by 2027, with a continuous increase in the proportion of special alloy resistor output;
Monthly capacity exceeding 100 billion pieces by 2030, aiming to rank among the world’s top three resistor manufacturers.
Moving forward, FOSAN will keep increasing investment in manufacturing bases and automotive-grade R&D laboratories. Leveraging our complete product lineup, rigorous automotive-grade quality control and large-scale intelligent manufacturing strengths, we will continuously advance domestic substitution of high-end resistors, building a stable, self-controllable component supply chain foundation for the industrial chains of AI computing hardware and industrial automation equipment.
