Dongguan Yiliyi Electronics Co., Ltd. and Dongguan Xinribao New Material Co., Ltd. are both wholly-owned subsidiaries of Shanghai Yiliyi Electronic Devices Co., Ltd. The company's main business scope is new electronic ceramic materials and components, such as barium titanate semiconductor electronic ceramics, multi-layered ceramic components, and has core technologies in the production and application of barium titanate semiconducting ceramics. It has obtained six national patents, including electronics. The invention relates to two invention patents: a ceramic reducing atmosphere firing method and a ring varistor forming method.

The company's products are: Barium titanate toroidal varistors, Multi-layer chip type high-voltage ceramic capacitors, Multi-layer chip zinc oxide varistors, Axial lead type multi-layer high-voltage ceramic capacitors. Varistors, single-layer chip microwave capacitors.
Dongguan Yili Hao Electronics Co., Ltd. is the first company in China to mass produce barium titanate ring varistors. The barium titanate ring varistor is mainly used for the spark elimination and electromagnetic interference absorption when the micro DC motor is working, thereby achieving the purpose of eliminating electromagnetic pollution and prolonging the life of the motor. After several years of research and development, the product's performance has reached the international advanced level, and it has been widely recognized and used by domestic and foreign manufacturers, including Japanese and Korean motor manufacturers.

The company adheres to the concept of sustainable development, eliminates the use of substances harmful to the environment during the research and production process, and produces and sells products that comply with ROHS regulations and meets customers' requirements for lead-free high-temperature welding.

Dongguan New Company obtained the TS16949 and ISO9001 quality system certification in October 2016. The company will strive to improve the management system, strengthen 6S management and process control, in order to achieve continuous improvement of product quality, to provide customers with satisfactory product services.
