Why Your Supply Chain Struggles with Conventional Transformers

High purchase price – legacy suppliers charge 25‑40% above market.
Oversized footprint – bulky designs increase PCB area and shipping volume.
Inconsistent quality – batch‑to‑batch variance leads to warranty claims.
Long lead times – 8‑12 weeks for custom orders delay product roll‑out.
Limited certification – missing CE/FCC makes US entry risky.

Result: 37% higher total cost of ownership and missed market windows.
