Patent Certificates
Patent Certificates & Compliance Documents

Our patent certificates reflect continuous engineering work in magnetic component design, structural optimization and manufacturing improvement. For custom transformers, inductors, chokes and ferrite-based components, reliable performance often depends on more than material selection alone. It also requires practical design experience in winding structure, insulation layout, thermal behavior, EMI suppression and production consistency.

Nanjing Infinity Technology continues to improve its magnetic component solutions through application-driven development. These patent records represent selected achievements related to product structure, process optimization and performance-oriented design, helping customers evaluate our technical foundation beyond standard product specifications.

Relevant patent and technical documentation can be provided as supporting material for supplier qualification, engineering review and customized project discussions where applicable.
