TDK Electronics has introduced an extension to its ERU27M series of SMD high current flat wire inductors. These inductors feature an isolated alloy powder core and flat wire helical winding, making them suitable for automotive and industrial applications that require higher power densities and currents. The alloy powder core material used in these inductors offers a softer saturation characteristic compared to previous core materials. The series consists of four variants designed for rated currents ranging from 36 A to 48 A and inductance values from 2.3 µH to 8.5 µH. With DC resistances as low as 0.68 mΩ to 1.66 mΩ, these components have compact dimensions of 27.1 mm x 25.55 mm and a height ranging from 14.1 mm to 16.4 mm. They are designed to operate within a temperature range of -40° C to 150° C.
The newly introduced inductors are AEC-Q200-qualified and feature magnetic shielding as well as robust construction. They incorporate a third pin that is not electrically connected, allowing them to be used in various applications such as DC-DC converters, voltage regulator modules, and point-of-load converters in the automotive sector, as well as in solar converters. These inductors are specially designed to meet the demanding requirements of automotive and industrial applications that require high power densities and currents. They are also capable of operating in a wide temperature range, making them suitable for harsh environments.
TDK Electronics offers options for customization to help customers optimize space and cost according to their specific requirements. Customers can request certain production parameters to be changed or opt for fully customized designs based on their application needs. This flexibility allows TDK Electronics to provide tailored solutions to meet the unique requirements of customers in the automotive and industrial sectors.
