Frequently Asked Questions
What is the typical lead time for a custom common mode inductance order?
Standard stock items ship in 3‑5 business days. Custom designs (tolerance, current rating, or form factor) are prototyped within 7 days and mass‑produced in 2‑3 weeks.
Can you provide a free sample before committing to a large order?
Yes. We ship up to 10 pcs of your chosen specification at no charge (shipping cost borne by the buyer). Sample performance data is included.
Do you support OEM/ODM design services for high‑frequency applications?
Our 10 R&D engineers can co‑develop inductors up to 200 MHz, providing simulation, PCB layout recommendations, and full compliance documentation.
How do you ensure compliance with US regulations (UL, FCC) for exported parts?
All units undergo UL‑listed testing labs and receive a full Test Report, FCC Part 15 Declaration, and CE Declaration of Conformity before shipment.
What logistics options are available for US buyers?
We offer DHL Express, UPS Air, and FOB Shenzhen. For high‑volume orders, sea‑freight consolidation with customs brokerage is available.
