In the field of electronic components, thick film chip resistors have become core components in key areas such as industrial equipment, power supply applications, network communications and automotive electronics due to their high precision, high temperature resistance and strong power load capacity. However, in the face of increasingly complex application environments and stringent reliability requirements, the problem of sulfurization on the surface of resistors has become a challenge that cannot be ignored. Sulfurization not only affects the stability of the resistance value of the resistor, but may also cause circuit failure and even safety accidents, posing a serious threat to the long-term stable operation of the product.

FOSAN FRR Series: The Best in Anti-sulfurization Performance

In response to this industry pain point, FOSAN Electronics, relying on its deep accumulation in the field of electronic components, launched the FRR series of anti-sulfur thick film chip resistors. This series of products effectively resists the corrosion of sulfides through innovative materials and processes, ensuring the stable performance of resistors in harsh environments. Whether it is computers and multimedia electronic equipment with high-precision requirements, or industrial applications in high-sulfur environments, the FRR series can provide reliable solutions to ensure the stable operation of terminal products.

Excellent performance, proven by rigorous testing

During the development process, FOSAN FRR series anti-sulfurization thick film chip resistors have undergone a number of rigorous tests including temperature coefficient test, short-time overload test, solder resistance test and load life test. In particular, in the anti-sulfurization test, according to the international standard ASTM-B-809-95, after being stored without electricity in a sulfurized environment at 105℃ for 750 hours, the maximum resistance change is only ±(4.0% +0.05Ω), showing extraordinary anti-sulfurization ability.

Diverse packaging, flexible to meet various design requirements

In order to meet the diverse needs of different integrated circuit designs, the FRR series provides a variety of package size options. This flexibility not only reduces design costs, but also speeds up the product's time to market, providing engineers with more innovative possibilities.

Excellent power attenuation performance, suitable for high power applications

The FRR series also performs well in power handling. At ambient temperatures between -55°C and 70°C, its load power ratio is as high as 100%. Even in the high temperature range of 70°C to 155°C, the power attenuation shows a linear trend, ensuring the stable performance of the resistor under high temperature and long-term working conditions. This feature makes the FRR series particularly suitable for high-power integrated circuit design, effectively responding to the higher requirements of modern electronic equipment for power handling capabilities.

Foreign brands have great potential to replace domestic brands, helping domestic brands to rise

It is worth mentioning that the performance of FOSAN brand FRR series anti-sulfurization thick film chip resistors is on par with internationally renowned brands, and even surpasses them in some aspects. With the continuous advancement of domestic electronic component technology and the gradual expansion of market share, the FRR series is expected to become a strong competitor to foreign brands, providing domestic and foreign customers with better quality and more economical options. This will not only help promote the upgrading and development of the domestic electronic component industry, but also contribute to the rise of China's electronic manufacturing industry in the global market.
