Tonghuashun (300033) Financial Research Center, May 07crashofthetitans, some investors asked Platinum New Materials (300811). Hello Secretary, Hello Secretary, please introduce the core selection software independently developed by your company.

The company replied, Hello, the calculation and theory of magnetic materials have always been relatively complex, while magnetic material electronic components account for a considerable proportion in circuits. The familiarity with magnetic materials will greatly affect the design of the entire circuit. Therefore, engineers have to spend extra time studying the characteristics of magnetic materials when designing magnetic components in circuits to solve the problem of selection. In order to free electronic development engineers from cumbersome material characteristics research and devote more energy to functional development, the company has specially developed core selection software. This software mainly focuses on the selection and calculation of filter inductors, energy storage inductors, PFC inductors, and reactors. Thank you!
