Why Purchasing Managers Struggle with Conventional Inductors

High Unit Cost: Legacy suppliers charge 30‑45% above market average.
Inconsistent Quality: 12% of batches fail to meet IEC‑60784 standards, causing production delays.
Long Lead Times: 6‑8 weeks from order to delivery – unacceptable for fast‑moving projects.
Limited Customization: Standard sizes force redesign of PCB layouts, raising engineering overhead.
Regulatory Uncertainty: Missing CE, RoHS, or FCC certifications can stall product launches in the US and EU.

Result: Your bottom line suffers, time‑to‑market slows, and compliance risks increase.
