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 2ย xย 3.9ย ยตH to 2ย xย 47ย ยตH and are designed for maximum rated currents from 2.83ย A to 7.05ย 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 16.1ย A. The magnetically shielded inductors have dimensions of just 12.5ย xย 12.5ย xย 10.5ย mm3 and are designed for a wide temperature range of -55ยฐC to +150 ยฐC. 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.
