Inductors: Compact dual inductors with high saturation current

Inductors: Compact dual inductors with high saturation current

TDK Corporation has extended its range of dual inductors to include the new EPCOS series B82477D6*. The seven series types 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 just 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 inductors offer very high coupling factors of the two windings from 97 to 99 per cent.

The fields of application of dual inductors are diverse: Indeed, they 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.

Main fields of application
  • Common-mode inductors in power supply lines
  • DC/DC converters in SEPIC topology
  • Flyback converters
Main features and benefits
  • High saturation currents of up to 16.1 A
  • Low dimensions of just 12.5 x 12.5 x 10.5 mm3
  • Wide temperature range of -55°C to +150°C
  • High coupling factor of up to 99 per cent
