1. The Real Cost of Poor EMI Suppression

Unreliable RF performance leads to warranty claims that can increase after‑sales costs by up to 37 %. In high‑frequency medical devices, a single EMI incident can delay product certification by months.

Many US manufacturers report high price tags from overseas suppliers yet receive low‑quality chokes that fail FCC/CE testing, forcing redesigns and production downtime.

According to a 2025 IEC survey, 45 % of firms cite inadequate common‑mode choke performance as the primary cause of product recalls.
