The inductors designed for high currents and compact sizes enhance power management in automotive and industrial applications efficiently.
TDK Corporation has expanded its ERU27M series of SMD high current flat wire inductors, which feature an isolated alloy powder core and flat wire helical winding. This enhancement caters to the growing power densities and currents in automotive and industrial applications by utilizing an alloy powder core that exhibits a softer saturation characteristic than previously used materials.
The main applications for these energy storage chokes include DC-DC converters, VRM modules, POL converters, and solar converters.
The series is designed for rated currents ranging from 36 A to 48 A and offers inductance values from 2.3 µH to 8.5 µH. DC resistances range from 0.68 mΩ to 1.66 mΩ. The components boast compact dimensions of only 27.1 x 25.55 mm, with heights varying from 14.1 mm to 16.4 mm, and are capable of operating in temperatures from -40 °C to +150 °C.
These magnetically shielded and robust inductors, featuring a third pin that is not electrically connected, are AEC-Q200 qualified and suitable for use in DC-DC converters, VRM modules, and POL converters, particularly in the automotive sector, as well as in solar converters.
Some of the key features and benefits of the inductors include:
- High rated current up to 48 A
- Extremely low DC resistance down to 0.68 mΩ
- Very low profile and small footprint
- Insulating alloy powder core
- Magnetically shielded
- Third pin that is not electrically connected for improved mechanical reliability
- Surface-mountable
- Qualified to AEC-Q200
In addition to its standard portfolio, TDK Electronics offers space and cost-optimized solutions by adjusting production parameters and providing fully customized designs.
