TDK Corporation has expanded its IEC AC mains power socket inlet filter series 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 a minimized 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 AC at 50/60 Hz. They are designed for rated currents from 1 A to 10 A. The B84771* version is even available for rated currents up to 20 A. The filters are attached to the equipment with screws or snap-in clips. They are connected via flat connectors with dimensions of 6.3 mm x 0.8 mm or litz wires (B84771*).
All filters were 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. ENEC approval is pending.
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.
