Gathering Industry Talents To Assist Domestic Devices！
In the midsummer of August, the sun is scorching, and the 2021'China Electronic Hotspot Solutions Innovation Summit officially kicked off in this scorching weather.
This summit was hosted by Bigbit Information, co-organized by Guangdong New Energy Vehicle Industry Association, Guangdong Charging Facilities Association, Guangdong Home Appliances Chamber of Commerce, Guangdong Components Industry Association, and China Power Supply Society Magnetic Technology Committee, and hosted by Semiconductor Device Applications, Magnetic Components and Power Supply, and International Cables and Connections.
Participating in the entire summit were many well-known companies such as Huawei, BYD, Xiaopeng Motors, Lenovo Design Institute, Foxconn, Great Wall Technology, Huntkey Chiyuan, Aohai Technology, Magmet, Topband, Costar, Lianbao, Kelu Electronics, Chaoclocking Three, Tianyin Electronics, Haowen Intelligent, Jialong Haijie, Kelike, Spit, Pintai Electronics, and Dianbang New Energy. The Solution Innovation Summit was also officially opened in this hot weather.
Elites from different fields gathered together for two days to discuss and exchange ideas on major hot electronic solutions.
PROSEMIMicroelectronics Technology (Suzhou) Co., Ltd. provides customers with more professional and diverse combination circuit protection. The R&D, production and sales teams are all elites from the component field, with many years of industry experience, and can provide highly stable and cost-effective products. At the same time, they will also develop and launch new products together with end customers.
PROSEMI has a team with more than 20 years of industry experience in the field of current sensor resistors (chip alloy resistors). At present, such devices are mainly dominated by European, American, Japanese and Taiwanese manufacturers, including Taiwanese manufacturers with main production bases in Taiwan and Southeast Asia. The epidemic and the international environment have caused the supply of such products to be much worse than before. PROSEMI's advantage of localized production (Suzhou Industrial Park) will shorten the delivery from 16 weeks to 4 weeks, and large-scale production (currently increased to 60KK/M), and it continues to be recognized by first-tier manufacturers such as Lanwei, Tobang, BYD, and Bosch. At the same time, the company is receiving APTIV review, a leading global automotive parts company.
Current sensor resistor
Current sensor resistor product structure
| CSR parameters and characteristics | trend | Remark |

Trends in Current Sensors
In addition to the above current sensor resistors, PROSEMI also displayed a line-speed fuse recently developed jointly with a well-known domestic first-line electric bicycle manufacturer. This line-speed fuse complies with the national standard GB17761-2018 for electric bicycles and provides a safe and reliable protection device. The fuse has the advantages of high reliability, strong breaking capacity, and easy installation. It can currently provide specifications of 20A~60A and has received the first batch of trial production orders from the electric bicycle industry!
PROSEMI Microelectronics Technology (Suzhou) Co., Ltd. is willing to work with more partners for mutual benefit and win-win results, and contribute to the development of domestic devices!
