Electrical engineering focuses on high‑power, low‑frequency systems (power generation, transmission, heavy‑duty motors). Electronic engineering deals with low‑power, high‑frequency circuits (signal processing, micro‑electronics). Selecting the correct component class avoids over‑engineering and reduces cost.
Yes. Our 10 R&D engineers develop custom transformers for power‑grid projects and precision inductors for electronic modules, all under a single PO and single‑source logistics.
Standard stock items ship within 4‑7 days. For OEM/ODM projects, we guarantee delivery within 30 days after design approval, thanks to our 14 automated production lines.
All products undergo FCC Part 15 testing, UL certification (when requested), and RoHS screening. Test reports are provided with every shipment.

We offer 24/7 technical hotline, on‑site failure analysis within 48 hours, and a 12‑month warranty covering material defects.
