TE Connectivity / Schaffner FN 3287/3288 EMC/RFI Filters
TE Connectivity / Schaffner FN 3287/3288 EMC/RFI Filters are based on an innovative filter topology with state-of-the-art EMI attenuation. These filters ensure compliance with Class C2 or C1. The FN 3287/3288 filters come in a slim book-style shape that saves space and allows for installation next to inverters, converters, or motor drives. These TE Connectivity / Schaffner filters act as solid safety connector blocks and are available in HVIT, IT, and low-leakage current versions. The FN 3287 filters offer standard attenuation performance, while the FN 3288 filters provide high attenuation performance. Typical applications include process automation equipment, 3-phase power supplies, low-leakage current requirements, and IT power distribution networks.
