Why Your Supply Chain Is Losing Money Without Proper Common Mode Chokes

1. Unexpected EMI‑Related Downtime

According to IEC 61000‑4‑3 data, 37% of equipment failures in manufacturing plants are traced to inadequate EMI filtering. Each hour of unplanned shutdown costs $12,800 on average.

2. Overpriced Low‑Quality Chokes

Low‑cost imports often fail the FCC Part 15 test, forcing re‑engineering and additional testing—adding 15‑25% extra OPEX per project.

3. Lengthy Lead Times From Unreliable Suppliers

Typical overseas lead times exceed 45 days. In fast‑moving industries, this translates to missed market windows and lost revenue.
