Würth Elektronik presents WE-XHMA SMD power inductor for automotive applications
Würth Elektronik has introduced an AEC-Q200 certified SMD inductor. WE-XHMAS features a high current capability of up to 50.6A saturation current and the ability to handle high current transient peaks. Its design, with flat wire coil and a composite core material, is claimed to ensure low copper losses and stable behaviour 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, according to the company. The higher energy density and the compact design due to the use of flat wire are claimed to make WE-XHMA interesting for switched-mode power supplies. Flat wire is said to have 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, claimed to be better than that of round wire.
The compact moulded magnetically shielded coils are AEC-Q200 certified and have an operating temperature range of -40 degree C to +125 degree C. WE-XHMA is available in SMT styles 6030, 6060, 8080, 1090 and 1510 and with saturation currents from 9.3A to 50.6A. Free samples for developers are provided.
