Compact dual inductor with high saturation current
TDK has extended its dual inductor range with a higher saturation current for DC-DC converter designs.
The seven devices in the EPCOS B82477D6 dual inductor series cover 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.
A special feature of the inductors, which are certified according to AEC-Q200 and compatible with RoHS, are the high saturation currents of up to 16.1 A. The magnetically shielded inductors have dimensions of 12.5 x 12.5 x 10.5 mm3 and are designed for a wide temperature range of -55°C to +150 °C. Depending on the type, the dual inductor devices have very high coupling factors of the two windings from 97 to 99 percent.
The devices can be used as coupled inductors in a DC-DC converter using a SEPIC (Single-Ended Primary Inductance Converter) architecture or 1:1 transformers in flyback topologies. A further application involves use as a common-mode inductor in power supply lines as the isolation voltage between the two windings is over 500 V.
