TDK has extended its range of coupled inductors to include the new EPCOS series B82472D6*. The nine series types cover an inductance range of 2 x 2,2 µH to 2 x 47 µH and are designed for maximum rated currents of 1,1 A to 4,3 A. The RoHS-compliant chokes are certified in line with AEC-Q200 and feature high saturation currents of up to 7,95 A.
The magnetically shielded inductors have dimensions of just 7,3 x 7,3 x 4,8 mm and are designed for a wide temperature range of between -55°C and +150°C. Depending on the type, the chokes offer very high coupling factors of the two windings, from 97 to 99%.
These compact, robust components prove to be useful in a wide range of applications: they are ideal in various galvanically non-insulated DC/DC converter topologies such as SEPIC, Cuk and Zeta and can also be used as transformers in flyback and multi-output buck topologies. In the latter, coupled inductors provide a second output voltage. Furthermore, they can be utilised as common-mode chokes in power supply lines. The insulation voltage between the two windings is >500nbsp;V.
