1️⃣ Excessive Pricing – 45% of purchasing managers report that standard common mode chokes cost >30% more than budgeted.
2️⃣ Inconsistent Quality – Field failures rise 22% when inductance tolerance exceeds ±10%.
3️⃣ Long Lead Times – Average delivery from overseas suppliers stretches beyond 45 days, stalling production schedules.
4️⃣ Regulatory Gaps – Non‑CE/FCC‑certified parts cause costly re‑testing and shipment delays.
5️⃣ Limited Customization – One‑size‑fits‑all designs force engineers to add extra components, inflating PCB real‑estate and assembly time.
Result: Higher OPEX, delayed product launches, and jeopardized compliance.
