Two new Series of IEC inlet filter from TDK

inlet filter, TDK, fuse, power supply

TDK Corporation has expanded the proven EPCOS B84771* IEC 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.

Glossary

  • IEC: The International Electrotechnical Commission is an international standards organization based in Geneva, Switzerland, that prepares and publishes standards for all electrical, electronic and related technologies. Some standards are developed in collaboration with ISO, the International Organization for Standardization.
  • Inlet filters: These filters employ capacitors and inductors to discharge high-frequency interference.
