  • Covers a wide inductance range from 2 x 3.9 µH to 2 x 47 µH and currents from 2.83 A to 7.05 A
  • Offers a range of high coupling factors

TDK Corporation has extended its range of dual inductors by introducing the new EPCOS series B82477D6. The series covers an inductance range from 2 x 3.9 µH to 2 x 47 µH and are designed for maximum rated currents from 2.83 A to 7.05 A.

These dual inductors 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.


These dual inductors have high saturation currents of up to 16.1 A and are designed for a wide temperature range of -55 degrees Celsius to +150  degrees Celsius. The inductor series offers a range of high coupling factors of two windings from 97 to 99 per cent.

The dual inductor series is certified according to AEC-Q200 and compatible with RoHS. The magnetically shielded inductors have dimensions of just 12.5 x 12.5 x 10.5 mm3.
