Why Your Current EMI Strategy Falls Short

1. High Cost of Conventional Chokes – OEM catalogs often list > $4.50/unit for 1 1 common mode chokes, eroding profit margins.

2. Inconsistent Quality – Variations in inductance and DC resistance lead to failed compliance tests (FCC, CE) and costly redesigns.

3. Long Lead Times – Overseas suppliers average 6‑8 weeks, delaying product launches and inventory turnover.

4. Limited Customization – Standard parts cannot meet niche specifications such as 1 µH at 100 kHz with <1 % tolerance.

5. Regulatory Risks – Non‑RoHS or non‑ISO‑9001 components expose you to audit failures.

Frequently Asked Questions

What is the typical lead time for a 1 1 common mode choke order?

Standard production is 7 business days. Express service (48 h) is available for an additional 15 % surcharge.

Can you customize inductance or package size?

Yes. Our R&D team can adjust inductance (0.5‑5 µH), tolerance (±0.5 %‑±2 %), and select between SMD 0805, 1206, or through‑hole 1206 footprints.

What certifications do your chokes hold?

All units are CE, FCC, RoHS, UL, ISO 9001, and for medical‑grade orders ISO 13485 and IEC 60601‑1 compliant.

How do you handle shipping to the United States?

We offer DDP (Delivered Duty Paid) to all US ports, with real‑time tracking. Air freight is 3 days; sea freight 12‑14 days.

Is a sample available before bulk purchase?

Free engineering samples (up to 5 pcs) are shipped within 3 days after NDA sign‑off.
