Flat Wire Coils in New Inductors from Wurth Elektronik

Wurth Elektronik has expanded its lines of high current inductors with new models using flat wire coils.  

With WE-HCFT 2504, shown at top, the company has added a model with an unusually low overall height to its family of THT high-current inductors. The flat wire coil with MnZn core is only 4 mm high and its current-carrying capability extends to 33 A, achieving one of the highest power density and efficiency within HCFT family. 

Shown below is its WE-HCF-2010 high-current inductor. With innovative improvements in its internal design, the latest model of WE-HCF-SMT high-current inductors sets new standards in its class, says Wurth.  The design offers significantly better characteristics than previously available inductors in this size with inductance values up to 2 μH and saturation currents up to 25% higher than comparable products. The magnetically shielded flat wire coil with MnZn core impresses with a low resistance of 0.84 mΩ and low core losses. 

Potential applications for the inductors include POL regulators, high-efficiency DC/DC converters, high-current switching power supplies, forward converters, half-bridge and full-bridge converters, as well as battery chargers and solar inverters. For more info, see www.we-online.de
