TDK Expands Coupled Inductor Portfolio

     The TDK Group expands its coupled inductor product portfolio with the launch of the new EPCOS B82472D6 series of coupled inductors. The new series includes 9 products with inductances ranging from 2 x 2.2 µH to 2 x 47 µH and maximum current ratings from 1.1 A to 4.3 A. Among them, the RoHS compliant choke is AEC-Q200 certified and has a large saturation current of up to 7.95 A; while the magnetically shielded inductor measures only 7.3 x 7.3 x 4.8 mm and is suitable for -55 °C to +150 Wide temperature range in °C. The coupling factor of the inductor is from 97% to 99%, depending on the model.

     These components are compact, rugged, field-proven and widely used: in various non-isolated DC/DC converter topologies such as SEPIC, Cuk and Zeta; as transformers in flyback and multi-output buck topologies . In the latter application, a coupled inductor is used to provide the secondary output voltage. In addition, these components have >500 V insulation between the two windings and can be used as common mode chokes in power lines.
