High Power ER2828 Flyback Power Transformer High Frequency Transformer

The ZXY ER2828 Flyback Power Transformer is engineered for high power density applications. Featuring elongated ER type magnetic cores and flat or Leeds wire winding structures, this transformer effectively minimizes skin effect losses and leakage inductance at high frequencies. Capable of handling tens to hundreds of watts in a compact form factor, it is ideal for DC-DC conversion applications requiring input and output electrical isolation, including switching power supplies, industrial power supplies, and LED drivers.

Key Advantages
  • Multi-output capability: The flyback topology combined with ER2828 can easily achieve 3-4 sets of mutually isolated output voltages, meeting various power supply requirements for communication boards
  • Wide input range: Operates stably from 36V to 72V under wide voltage input, adapting to communication power supply fluctuation characteristics
  • Isolation and voltage resistance: Primary to secondary withstands 3000VAC high voltage testing, meeting safety specifications for communication equipment
  • Compact size: Approximately 31mm x 35.5mm footprint, suitable for high-density layout of communication boards
