Custom EFD20 Low Profile High Magnetic Permeability SMPS Transformer for Fast Charger Adapter

EFD20 is a flat high-frequency ferrite transformer dedicated to switching power supplies. It realizes high-efficiency AC-DC voltage conversion, energy transfer and voltage transformation in flyback/forward power supply circuits. It reduces electromagnetic interference, optimizes power conversion efficiency, and provides stable isolated DC power output for lightweight electronic power equipment.

EFD20 features low-loss manganese-zinc ferrite closed magnetic core with conversion efficiency up to 92% and low energy consumption. The ultra-thin flat profile design with low height perfectly fits thin chargers and slim power modules. Dual installation options of vertical and horizontal skeleton with standard PCB through-hole pins provide flexible layout on circuit boards.
