ETD34 Horizontal Pin Type High Frequency Transformer
The ETD34 high frequency transformer is a horizontal pin-type (through-hole / PCB mounting) switching power transformer built on an ETD34 ferrite core. Designed for continuous operation in solar inverters, UPS systems, EV chargers and industrial SMPS, it delivers stable power conversion, low temperature rise and reliable insulation under long-duty and high-ambient conditions. Windings, turns ratio, inductance, pin-out and creepage design are fully customizable to your circuit schematic.
