High current inductor for automotive applications
Würth Elektronik introduces another AEC-Q200 certified SMD inductor: WE-XHMA features an extremely high current capability of up to 50.6 A saturation current and the ability to handle high current transient peaks. Its design with flat wire coil and a composite core material ensures low copper losses and stable behavior under temperature fluctuations.
WE-XHMA is particularly suitable for use in DC/DC converters for high current supply and field programmable gate arrays (FPGA), as well as filter applications. It is particularly useful when used in switching power supplies: In contrast to conventional core materials, the compact coil shows hardly any temperature-dependent fluctuations in terms of inductance and saturation current. The higher energy density and the compact design due to the use of flat wire also make WE-XHMA interesting for switched-mode power supplies. Flat wire also has the advantage that a larger cross-sectional area can be achieved with the same space requirement, thereby reducing resistance. Furthermore, it shows a lower skin effect at higher frequencies and the heat dissipation towards the circuit board is, because of the flat thermally conducting surface, also better than round wire.
The compact molded magnetically shielded coils are AEC-Q200 certified and have an operating temperature range of -40°C to +125°C. WE-XHMA is available from stock in SMT styles 6030, 6060, 8080, 1090, 1510 and with saturation currents from 9.3 to 50.6 A. Free samples for developers are provided.
