1. High Unit Cost – Imported flyback inductors from traditional suppliers average $4.80 / piece, inflating BOM by up to 22 %.
2. Inconsistent Quality – 37 % of US OEMs report >5 % failure rate during qualification because of tolerance drift and insufficient RoHS compliance.
3. Long Lead Times – 6‑8 weeks from order to delivery slows product launches, especially for fast‑moving medical devices.
4. Limited Customization – Off‑the‑shelf parts cannot meet the tight inductance‑current specifications of high‑frequency power supplies.
5. Compliance Gaps – Missing CE, FCC, or UL certifications forces costly re‑testing.
