TE Circuit Protection Department Participates in Formulating Industry Standards

TE's TE Circuit Protection Department participated in the formulation and improvement of two new standards. They are the National Standard of the People's Republic of China, GB 9816.1-2013 Thermal Fuse Part 1: Requirements and Application Guidelines (abbreviation: Guidelines), and The People's Republic of China Machinery Industry Standard "JB/T 11627-2013 Self-recovering Miniature Fuse" (Abbreviation: Standard). The TE Circuit Protection Department participated in the formulation and improvement of these two new standards. The China Electric Apparatus Research Institute Co., Ltd. and other organizations also participated in the drafting and formulation.

Among them, the "Guideline" has been issued by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China and the Chinese National Standardization Administration Committee on December 31, 2013 and is scheduled to be implemented on July 13, 2015. In addition to some changes in the format of this standard, the new standard also added "the classification of thermal fuses, signs, mechanical requirements, electrical requirements, temperature testing, anti-rust technical requirements" and other content, applicable to the rated voltage does not exceed AC and DC 690V , Rated current no more than 63A thermal fuse. This standard applies to electrical and electronic equipment and similar components used in indoor environments, including hand-held and portable equipment. However, if the climate and other conditions of the environment in which the THERMAL-LINKS are located are similar to those specified in this standard, they are also applicable to THERMAL-LINKS that operate under non-indoor conditions.

The "Standard" belongs to the machinery industry standard of the People's Republic of China and has been issued by the Ministry of Industry and Information Technology of the People's Republic of China on December 31, 2013 and was implemented on July 1, 2014. This standard specifies the technical requirements for dimensions and terminals, electrical requirements, and test methods for self-recovering miniature fuses. It applies to rated voltages up to 600 V and holding currents up to 30 A. It consists of a polymer positive temperature coefficient material (PPTC). Self-recovering miniature fuses. This type of fuse is mainly used for over-current protection. In some applications, it may have the function of over-temperature protection, but it is not suitable for replacing a small-sized fuse with a meltable structure that has a breaking circuit current capability. Self-recovering miniature fuses can be used in batteries, switching power supplies, mobile phones, USB interfaces, and lighting fixtures.

Dr. Liu Jianyong, senior R&D manager of the Department of Circuit Protection, commented: “In recent years, electronic and electrical devices, including portable and consumer electronics, have become increasingly smaller and more versatile, as well as circuit protection devices such as thermal fuses and self-healing miniature fuses. The requirements are also increasing.The TE Circuit Protection Department is dedicated to satisfying customers' various needs. By participating in the formulation and improvement of these standards and making the development of circuit protection products more standardized, TE circuit protection devices can provide a variety of electronic products and applications. Reliable protection."

Mr. Dong Yong, Application Engineering Manager of the Department of Circuit Protection said: "With the development of circuit protection technology, it is necessary to further regulate the dimensions, electrical performance requirements, test methods, and environmental conditions of use from such aspects as the design, manufacturing, testing, and testing of devices. As the world's leading circuit protection expert, TE Circuit Protection Department has been leading the development of thermal fuse (fuse) and resettable device technology for many years, possessing the most advanced technology and the most extensive product line, participating in the formulation and improvement of this The two new standards are evidence of TE's leading technology protection department."
