Why Your Current Coupled Inductors Are Holding You Back

  • Excessive Cost: Average market price for standard coupled inductance exceeds budget targets by 25 %.
  • Unreliable Quality: 30 % of shipments fail IEC‑60747 tests, causing production delays.
  • Long Lead Times: Typical Chinese suppliers quote 8‑12 weeks, disrupting fast‑paced assembly lines.
  • Compliance Gaps: Missing RoHS, FCC, and UL certifications leads to costly redesigns.
  • Limited Customization: Off‑the‑shelf designs cannot meet high‑frequency (>500 kHz) or low‑noise (<‑85 dB) requirements.

Data point: A 2025 survey of 120 U.S. manufacturers showed 68 % consider magnetic component reliability a top‑three factor for ROI.

Frequently Asked Questions

What is the typical lead time for custom coupled inductance orders?

Standard OEM orders ship in 5‑7 business days after design approval; ODM projects average 3‑4 weeks depending on volume.

Can you meet U.S. UL and FCC certification requirements?

Yes. All our coupled inductors are tested against UL 60950‑1, UL 61000‑4‑2, and FCC Part 15. Test reports are provided with every shipment.

Do you offer low‑volume prototyping?

Prototype runs start at 100 pieces with a 48‑hour turnaround for most standard specifications.

What payment methods are accepted for international orders?

We accept T/T, L/C, PayPal Business, and major credit cards (Visa, MasterCard). Terms can be negotiated for qualified accounts.

How do you handle after‑sales support and warranty?

All products carry a 12‑month warranty. Our technical support team is available 24 × 7 via email, phone, and WhatsApp.
