Wurth Electronics WE-FLEX HV is the first transformer with insulation voltage of 1.5 kV_AC in the product portfolio. Some configurations provide basic insulation with clearance and creepage distances greater than 3 mm. The WE-FLEX HV series has up to 30% lower core losses than the WE-FLEX due to the newly developed state of the art MnZn core material. The flexibly usable SMD transformer is suitable for all types of isolated DC/DC converters in industrial and telecom applications.
