WE-OLEFD Offline Transformers

Würth Elektronik WE-OLEFD Offline Transformers include transformers crafted for AC/DC converters featuring a versatile output voltage range of 85V_AC to 265V_AC. These modules are engineered to comply with IEC 61558-2-16 standards for reinforced 400V_DC operating voltage. Würth Elektronik WE-OLEFD Offline Transformers come in EFD20 THT, EFD20 SMT, and EFD25 THT low-profile package variants. The switching frequency of the offline transformers spans from 68kHz to 250kHz.
