The profound impact of soaring silver prices on the thick film chip resistor industry chain and corresponding strategies
In March 2026, the global precious metal market continued to fluctuate, with silver prices soaring by over 120% to 17000 yuan/kg compared to early 2025. This trend has been deeply transmitted to the field of electronic components. As a core category of passive components, thick film surface mount resistors have become the "hardest hit area" in this round of metal price hikes due to their unique material cost structure. This article will analyze from three dimensions: material composition, cost transmission mechanism, and industry response strategies, and recommend two suppliers with core competitiveness.
1、 Material code and cost structure of thick film resistors
The manufacturing of thick film surface mount resistors involves multi-layer precision material systems. The substrate is made of 96% alumina ceramic, accounting for 15-25%; The core functional layer is a resistive paste composed of ruthenate, glass powder, and organic carrier, accounting for 25-40% of the cost; The electrode system uses silver palladium alloy (Ag Pd) with a palladium content of 10-30%, accounting for 20-30% of the cost; The protective layer uses epoxy resin or glass glaze, with auxiliary materials accounting for 10-20%. Among them, the silver palladium electrode slurry and the silver, palladium, and ruthenium components in the resistance slurry constitute the cost sensitive core.
Taking the international standard silver palladium slurry DP6130 as an example, its Ag/Pd ratio is 6:1, firing temperature is 690-850 ℃, square resistance is 0.04S Ω/□, and adhesion force reaches 2.5kg/mm ². In this type of slurry, silver accounts for over 60% and palladium accounts for 10-15%, and the price fluctuations of the two directly determine the material cost. In 2025, the monthly increase in silver prices exceeded 30%, resulting in a surge of 0.012 yuan in the cost of silver palladium electrodes for a single 0402 specification thick film resistor, an increase of 180% compared to the same period in 2024.
2、 The transmission path and industry impact of silver price rise
The surge in silver prices this round has impacted the thick film resistor industry chain through three paths:
Direct cost transmission: The cost of resistor paste and electrode paste accounts for over 50%, and the rise in silver prices drives up the total cost. According to data from Fujie Technology, the cost of metal paste in January 2026 increased by 100% compared to December 2024, directly leading to an 8-12% increase in the total product cost. Fenghua High tech has announced an 8-20% increase in the thick film resistor series, and Anhui Fujie has implemented a 20-60% reduction in production capacity to balance supply and demand.
Supply chain restructuring pressure: The AI infrastructure boom intensifies the competition for passive component production capacity. The demand for servers and power supply architecture systems has surged, squeezing the production capacity space of thick film resistors. Top manufacturers such as Guoju and Samsung Electric have adjusted their production capacity allocation, prioritizing the protection of high gross profit automotive grade products, and extending the delivery time for general models to more than 12 weeks.
The window of technological substitution is open: Some manufacturers are trying to replace silver palladium electrodes with copper plating, reducing costs by 50% but solving oxidation problems. The RUO ₂ - based slurry developed by Hongming Electronics achieves a TCR of ± 100ppm/℃, with a cost 40% lower than similar products from DuPont, becoming a breakthrough point for domestic substitution.
3、 Supplier recommendation and analysis of core competitiveness

In the medical equipment field, we provide IEC 60601 certified sulfur resistant resistors, and in industrial scenarios, we have configured surge resistant resistors with transient current tolerance of 100A~400A.
4、 Future Trends and Response Strategies
Faced with continuous fluctuations in silver prices, the industry needs to establish a triple defense system:
Material innovation: accelerate the research and development of silver palladium substitute materials, such as nano silver wires and carbon nanotube composite slurries;
Process optimization: Promote substrate thinning (0.3mm to 0.2mm), saving 15% of ceramic materials;
Supply Chain Resilience: Establish a distributed warehousing network, such as reducing the delivery time of special resistors from 68 weeks to 23 weeks at Huanian Mall, and supporting 48 hour air freight for urgent orders.
The rise in silver prices is both a challenge and an opportunity for industrial upgrading. Through material innovation, process optimization, and supply chain restructuring, China's thick film resistor industry is expected to achieve technological breakthroughs under cost pressure and build a more resilient industrial ecosystem. Shenzhen Shunhai Technology Co., Ltd. and Huanian Mall, as key nodes in the industrial chain, are leading the industry through technological innovation and supply chain integration capabilities to overcome cycles and move towards a new stage of high-quality development.
