These ultra-low leakage powerline filters are designed for secure and safety‑critical systems that demand stringent control of earth leakage current while maintaining very high EMI attenuation over a broad frequency range. Using low‑leakage, current‑compensated inductor topology with carefully controlled line‑to‑earth capacitance, theTMF911UL series support compliance with TEMPEST and other high‑security EMC requirements without compromising operator safety or protection devices.
