Why Purchasing Managers Struggle with Conventional Transformers

High Unit Cost: Traditional suppliers charge 15‑25% above market average, eroding project budgets.
Inconsistent Quality: 30% of OEMs report failure rates > 5% after 6 months, leading to warranty claims.
Long Lead Times: 8‑12 weeks from order to delivery delays production schedules.
Limited Customization: Fixed winding ratios force redesign of PCBs and enclosures.
Regulatory Gaps: Missing CE, FCC or RoHS certificates cause customs hold‑ups.

If any of these sound familiar, you’re not alone—over 70% of B2B buyers in the U.S. cite “supplier reliability” as the top purchase blocker (2025 Global Procurement Survey).
