TDK expands its range of coupled inductors
TDK Corporation (TSE:6762) has extended 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.
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.

TDK Product Features
TDK’s coupled inductors are key components in power management systems in automotive and industrial applications. Their application field is versatile as they can be used in different DC/DC converter topologies, as 1:1 transformers in flyback converters and even as common-mode inductors in power supply lines. They can also be used as a 2-in-1 solution for multiphase topologies. Coupled inductors help significantly reduce the board´s complexity and improve the circuit's efficiency. TDK’s coupled inductors are available in four footprints from 7 x 7 mm to 12 x 12 mm and have an inductance range from 2 µH to 100 µH. The compact and robust design offers functional isolation up to 500 V and a temperature range of up to 150 °C. Most topologies require very tight magnetic coupling between the coil windings. TDK offers different versions specifically designed to provide high coupling factors up to 99.7 percent. However, tight coupling is not always desired. In this case, a version with loose coupling is also available in the product portfolio.
