B82477D6 Series Dual Inductors

 TDK Corporation has expanded its range of dual inductors to include the EPCOS series B82477D6. The seven series types cover an inductance range from 2 µH x 3.9 µH to 2 µH x 47 µH and are designed for maximum rated currents from 2.83 A to 7.05 A. A special feature of the inductors, which are certified according to AEC-Q200 and compatible with RoHS, are the high saturation currents of up to 16.1 A. The magnetically shielded inductors have dimensions of just 12.5 mm x 12.5 mm x 10.5 mm and are designed for a wide temperature range of -55°C to +150°C. Depending on the type, the inductors offer very high coupling factors of the two windings from 97% to 99%.

The fields of application of dual inductors are diverse. They can be used as coupled inductors in SEPIC (single-ended primary inductance converter) or 1:1 transformers in flyback topologies. A further application involves use as a common-mode inductor in power supply lines. The isolation voltage between the two windings is >500 V.
