This latest member of the WE-HCF series is loadable up to 36A and offers saturation currents up to 125 A. With its large wire cross-section, the inductor offers a 13% lower resistance than comparable products with 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 1.31 mΩ 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 for highly efficient DC/DC converters for individual and multiphase converters or for filtering audio applications. WE-HCF is also suitable for high current step-up converters.
