Against the accelerated electrification and intelligent transformation of the automotive industry, stricter standards are imposed on the stability and safety of automotive electronic systems. As essential basic components in vehicle circuits, chip resistors directly determine the reliability of the entire vehicle electronic system.
FOSAN Technology has long been engaged in the automotive electronics sector. The FRQ series automotive-grade thick film resistors are tailor-made for harsh automotive and industrial operating environments and have passed AEC-Q200 automotive qualification certification. Featuring stable performance and high dependability, they serve as core matching components for vehicle BMS and power control systems. Supported by large-scale production capacity, we deliver cost-effective and highly stable resistor solutions for the automotive industry.
As a domestic resistor manufacturer, FOSAN Technology consolidates product quality with robust mass production capacity. Our monthly production capacity reached 35 billion pieces in 2026, with plans to further expand output by 2030, ranking us among the industry leaders and maintaining top sales volume among domestic brands all year round.
Leveraging independent R&D and full-industry-chain production advantages, we have established a comprehensive product portfolio covering general chip resistors, automotive-grade resistors, alloy resistors and special-type resistors, catering to diverse demands from automotive, industrial, consumer electronics and other fields.
The FRQ automotive-grade thick film resistors boast prominent core advantages perfectly matching vehicle application scenarios. Adopting a multi-layer composite structure, they consist of high-purity alumina ceramic substrate, thick film resistance layer, insulating protective layer and thickened electrode layer from bottom to top.
The substrate ensures outstanding mechanical strength and thermal conductivity; the thick film resistance layer is made of high-stability paste via printing and sintering to realize precise resistance value and low temperature drift; the insulating layer shields against moisture, dust and other external interference to prevent performance degradation; the thickened electrodes improve electrical conductivity and soldering stability, avoiding poor contact caused by vehicle vibration.
The FRQ series fully embodies our strength in mass production and core technology. We exercise full independent control over the whole process including raw material procurement, production processing and finished product testing, which guarantees consistent product quality and enables rapid bulk delivery to meet market demands.
Equipped with high-purity alumina substrate, FRQ resistors feature excellent high temperature resistance and anti-aging performance, capable of withstanding high-temperature conditions in engine compartments. The thickened electrodes deliver low contact resistance and superior conductivity to reduce current loss and improve energy efficiency.
Manufactured in strict accordance with IATF16949 automotive quality management system standards, the products have undergone rigorous reliability tests including high & low temperature cycling, vibration and humidity resistance. They maintain stable resistance values with negligible drift within the wide temperature range from -55℃ to +155℃, perfectly adapting to extreme automotive working conditions.
Widely applicable to automotive power supplies, battery management systems, vehicle sensors and other core devices, FRQ resistors work steadily in high-voltage detection and charging control of new energy vehicles as well as signal transmission of industrial vehicle equipment.
Their precise resistance control and strong anti-interference capability effectively enhance control accuracy of automotive electronic systems and lower failure rates. Compact in size and easy to install, they fit high-density layout of vehicle PCB boards without structural modification, greatly boosting production efficiency.
Backed by large-scale production and strict quality management, FRQ automotive resistors ensure stable bulk supply with outstanding cost advantages. Committed to building a world-leading electronic component brand, we provide one-stop supporting solutions for automotive clients relying on 35 billion monthly output, full-range product lineup and professional technical services, helping customers cut supply chain costs and strengthen market competitiveness.
In the future, FOSAN Technology will keep increasing R&D investment in automotive resistors to optimize product performance, enrich product categories and expand production scale, striving to rank among the world’s top three manufacturers. We will always adhere to stringent quality standards, empower high-quality development of the new energy vehicle industry with more reliable automotive-grade resistors, and fulfill our mission as a pacesetter of domestic resistor industry with professionalism and solid strength.
