A flat wire power inductor with very high current loading capacity and efficiency has been introduced by Würth Elektronik eiSos, the WE-HCF in a 2815 package. The latest member of the WE-HCF series is loadable up to 36A and attains saturation currents up to 125A. With its large wire cross-section, the inductor offers a 13% lower resistance than comparable products on the market and attains an up to 82% higher saturation current.
WE-HCF in the 2815 package fills the gap between the previously available 2013 and 2818 packages and represents a further improvement of the SMT-mountable inductors – with up to 50% higher nominal currents than the 2013 series. The flat wire coil has a resistance of just 1.31mΩ and with its manganese-zinc-ferrite core, the magnetically shielded power choke shows very low core losses.
The component specified up to 125°C is suitable as a highly efficient DC/DC converter for individual and multiphase converters or for filtering audio applications. WE-HCF is also especially suitable for high current step-up converters.
