Compact dual inductors with high saturation current

TDK Corporation has increased its range of dual inductors to incorporate the new EPCOS series B82477D6*. The seven series types comprise an inductance range from 2 x 3.9µH to 2 x 47µH. They are intended for maximum rated currents from 2.83A to 7.05A. A particular feature of the inductors, which are certified according to AEC-Q200 and compatible with RoHS, is the high saturation currents of up to 16.1 A. The magnetically shielded inductors have dimensions of only 12.5mm x 12.5mm x 10.5mm3 and are created for a wide temperature range of -55C to +150C. Depending on the type, the inductors provide very high coupling factors of the two windings from 97% to 99%.

The fields of application of these dual inductors are diverse, including being used as coupled inductors in SEPIC or 1:1 transformers in flyback topologies. A further application includes employment as a common-mode inductor in power supply lines. The isolation voltage between the two windings is >500V.

Main fields of application comprise common-mode inductors in power supply lines, DC-DC converters in SEPIC topology, and flyback converters.
