Why Your Current EMI Solution Is Costing You More

In 2025, 62 % of manufacturers reported unexpected downtime caused by inadequate EMI filtering. The hidden expenses stack up fast:

Overpriced Off‑Shelf Chokes: Average unit price $2.85 USD vs. $1.90 USD for bulk‑custom OEM – a 33 % cost gap.
Inconsistent Quality & Reliability: Failure rates of 4.7 % per 10k h in low‑grade products lead to warranty claims.
Lengthy Lead Times: Typical 45‑day delivery vs. our 7‑day fast‑track for stocked SKUs.
Poor After‑Sales Support: 28 % of buyers cite delayed technical assistance as a deal‑breaker.

These pain points translate into lost revenue, missed certifications, and strained supplier relationships.
