Professional Audio Amplifiers – A US‑based OEM reduced total harmonic distortion by 0.15 % after switching to our low‑noise transformer, enabling a 12 % price cut on the final product.
Live‑Sound Mixing Consoles – Our custom‑wound units delivered a 30 % weight reduction, improving rack density for touring rigs.
Medical Imaging Devices – Certified under IEC 60601‑1, the transformers passed all EMI tests, allowing the client to fast‑track FDA clearance.
Our MOQ starts at 100 pieces for standard specifications. For OEM/ODM projects, we can accommodate 50 pieces with a short‑run tooling fee.
Yes. Every production batch is accompanied by a full test report and certificates (CE, FCC Part 15, RoHS 3) as part of our quality‑assurance package.
With our high‑speed logistics partner, standard air‑freight from Shenzhen to Los Angeles is 5‑7 days. We also offer DDP (Delivered Duty Paid) service for hassle‑free customs clearance.
We provide a 12‑month warranty, 24 h technical hotline, and free replacement for any units failing the initial performance test.
Our R&D team uses FEMM simulation and laser‑wound precision coils. Shielded enclosures and optimized magnetic paths keep EMI below –85 dB.
