TDK expands its coupled inductor product line

TDK announced yesterday that it has expanded 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 percent.

These compact, robust components proof 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 utilized as common-mode chokes in power supply lines. The insulation voltage between the two windings is >500 V.

Main applications

  • DC/DC converters such as SEPIC, Cuk or Zeta
