Circuit Protection Electronics EMC filter

FMAB NEO single-phase EMC filter for Protection Class II applications. The double-insulated filter with no protective ground expands firm’s EMC filter family to include both Protection Class I and Class II versions. The Class II version meets the more stringent requirements for critical medical systems and at-home medical care devices according to IEC 60601-1-11 & 12. These requirements include increased insulation safety testing, lower leakage current, and higher attenuation performance of electro-magnetic interferences, particularly symmetrical attenuation. Device meets requirements, with reinforced insulation inside of the filter and large plastic collars around the terminals. Additionally, the filters are hi-pot tested with 4kVac between L or N against the metal housing for a dielectric strength of >5.6kVdc, according to the requirements of IEC 60601-1. Leakage current ratings of < 5μA are available.
