Frequently Asked Questions

What is a power line common mode choke and why do I need it?

It is a passive magnetic component that suppresses common‑mode noise on AC/DC power lines, protecting downstream equipment from EMI‑induced failures.

Can you customize inductance and current rating?

Yes. Our R&D team offers OEM/ODM services for any inductance (10‑150 µH) and current rating (5‑30 A) within our production capabilities.

What are the payment terms for first‑time buyers?

We accept T/T 30 % deposit, 70 % balance before shipment, or L/C at sight. For qualified partners, Net 30 days is available.

How fast can you ship to the USA?

Standard air freight: 5‑7 business days. Express courier (DHL, UPS) – 3 days. Sea freight – 20‑25 days.
