Why Your Operations Still Suffer From EMI

Even with modern filters, many factories face recurring electromagnetic interference (EMI) that leads to:

↑ Equipment downtime – average loss of $12,500 per hour in U.S. plants (Source: IEC 2025 report).
↑ Product failure rates – up to 18 % higher return‑to‑vendor (RTV) incidents in medical devices.
↑ Compliance costs – additional testing to meet FCC, CE, and FDA standards.
Limited OEM flexibility – standard chokes cannot be customized for VHF (30‑300 MHz) applications.

These pain points directly hit your ROI and stretch your supply‑chain timelines.
