The following is an original comprehensive introduction to the fuse series of Nanjing SART Technology Development Co., Ltd. (SART). Based on its product technical characteristics, application fields, and industry status, the logical structure is clear and the language is fluent:
1、 Company background and technical strength
Nanjing Sute Technology was established in 1999 (asset restructuring in 2006) and is a national high-tech enterprise specializing in the research and production of electronic circuit protection components. The company has over 80 domestic and foreign patents (including 34 invention patents), participated in the development of 8 international IEC standards and 9 national standards, and serves as a member unit of the International IEC Small Fuse Secretariat. Through multiple certifications such as ISO9001, IATF16949 (automotive regulations), UL, PSE, etc., the product meets RoHS environmental requirements.
2、 Core fuse product series and characteristics
1. Surface mounted fuses
Ultra small series (S0603/S1206)
Model examples: S0603-F (0.5A~5.0A), S120 6-F (0.5A~7.0A)
Features: Optional fast/medium/slow break fuse characteristics, rated voltage 32V~250V, suitable for lightweight devices such as mobile phones and TWS earphones, with low internal resistance (meeting the power supply requirements of lithium batteries).
Technical highlight: The current of the S120 6-FG series reaches up to 45A, which is the highest level in the same size industry.
High current series (S6125/1032)
Model examples: S6125-H (block type, 3A~6A/250V), 1032-F (working current up to 100A)
Features: High breaking capacity, enhanced pulse resistance, suitable for new energy vehicle BMS, industrial power modules, and energy storage systems.
Advantage: The 1032 series has a current carrying capacity that is 2 years ahead of its peers in the same size.
Surge resistant series (S120 6-S)
Model example: S120 6-S (slow break type, 0.5A~7.0A)
Application: LED lighting driver (such as bulb lights, landscape lights), capable of withstanding frequent current surges.
2. Vehicle grade and high-voltage special scenario products
Vehicle grade fuse: high temperature resistant, sulfur resistant, certified by AEC-Q200, used for on-board chargers (OBC) and battery management systems.
High voltage fast break type: With a breaking capacity of 500A, it covers high reliability demand scenarios such as new energy photovoltaic inverters and charging piles.
3、 Technological advantages and innovation
Material technology: Using nano silicon carbide alumina ceramic substrate and nano silver paste to improve melting accuracy and durability.
Optimization of I ² t characteristics: precise control of the thermal energy value of the fuse, ensuring rapid interruption of abnormal currents and avoiding secondary damage.
Structural design: Patent protected component structure (such as surface mount overvoltage and overcurrent protection devices), enhancing breaking safety.
5、 Industry certification and market position
Certification: Global mainstream safety certifications such as CQC in China, UL in the United States, PSE in Japan, T Ü V in Germany, and KC in South Korea.
Market: The domestic chip fuse has the largest market share, with products covering the world. Customers include consumer electronics brands, automotive manufacturers, and industrial equipment suppliers.
summarize
Nanjing Sute, with "independent innovation+international standards" as its core, has become a domestic benchmark in the field of circuit protection through high-precision material technology and differentiated product design (such as 45A ultra small patch fuses and 100A automotive grade solutions). Its products combine high safety (excellent breaking ability), scene adaptability (from consumer grade to military aerospace), and environmental compliance, continuously empowering cutting-edge industries such as intelligent hardware and new energy.
