Core Products Introduction


As of 2023, Changrui has shipped over 100 million units of its standardized “CR-structure” toroidal inductors. While delivering products with zero quality defects, this innovation has also reduced the cost of base-mounted products by over 50%, saving customers tens of millions of yuan in direct material costs.

As of 2023, Changrui has shipped over 100 million units of its standardized “CR-structure” toroidal inductors. While delivering products with zero quality defects, this innovation has also reduced the cost of base-mounted products by over 50%, saving customers tens of millions of yuan in direct material costs.  In August 2023, based on the “CR-structure” toroidal inductor technology, Changrui introduced a new process for high-voltage insulation wires with zero fusing loss, achieving the “zero fusing loss” characteristic. This advancement addresses another key industry challenge, eliminating the high risk of short circuits and undetectable cold solder joints in insulation wire products.  Looking ahead, Changrui will continue to uphold its commitment to service and innovation, inherent in its corporate DNA. As a technology-driven enterprise, the company will keep developing new products and processes, contributing value to the industry and society.
