Why Your Current Coupled Inductor Strategy Is Costly

As a Purchasing Manager, you’ve likely faced one or more of these issues:

High unit price – Overseas suppliers often add hidden fees for tooling and low‑volume runs.
Inconsistent quality – Failure rates above 2 % lead to warranty claims and production downtime.
Long lead times – 8‑12 weeks shipping erodes your project schedule.
Limited customization – Standard parts don’t fit tight PCB footprints or specific inductance values.
Regulatory uncertainty – Missing CE, UL, or RoHS certifications stalls market entry.

According to a 2025 IEC survey, 38 % of US manufacturers cited “magnetic component reliability” as the top barrier to scaling new‑energy products.
