The Real Pain Points of US Purchasing Managers

You’re constantly battling:

High Unit Costs: Conventional wound transformers can add 20‑30% to BOM.
Quality Inconsistencies: Returns due to winding defects or insufficient EMI shielding.
Long Lead Times: Offshore factories often need 8‑12 weeks for a small batch.
Space Constraints: Modern equipment demands low‑profile, PCB‑mountable solutions.
Regulatory Hurdles: Need CE, UL, RoHS, and ISO‑9001 compliance for US imports.

According to a 2025 industry survey, 62% of US OEMs reported project delays caused by transformer supply issues.
