TDK has expanded the EPCOS B84771* IEC inlet filter family with two new series: the B84773* series features an integrated fuse, while the B84776* series has both a switch and a fuse.
All series are also available as versions for medical applications with a maximum leakage current of 2 μA. This makes them particularly suitable for applications for which minimal leakage current is important.
Both new series contain a fuse holder for two fuses with a diameter of 5 mm and a length of 20 mm. The power switch of the B84776* series is of bipolar design and thus separates the phase and the neutral conductor. The rated voltage of the connector filters is 250 V a.c. at 50/60 Hz.
The parts are designed for rated currents from 1 A to 10 A, with the B84771* version also available for rated currents up to 20 A. The filters are attached to the equipment with screws or snap-in clips and are connected via flat connectors with dimensions of 6,3 x 0,8 mm or litz wires (B84771*).
The filters are designed for maximum ambient temperatures of 85°C and are RoHS compatible. The B84771* versions already have UL/CSA/ENEC approval. Both B84773* and B84776* series have received UL/CSA approval and are pending ENEC approval.
Typical applications of these new IEC inlet filters are switch-mode power supplies, office and measuring instruments, arcade machines, electronic POS systems, small electrical machines, fitness equipment as well as equipment for medical applications.
