The Pulse Electronics PAT6261.XXXNL Series is a high-frequency wire-wound flyback transformer designed for the EFD15+ platform. These transformers offer functional insulation with a high isolation voltage of 1500Vrms and are suitable for operating frequencies up to 250kHz. They are engineered to prevent saturation in flyback topology applications, with guidance provided for calculating peak flux density and core loss.
