The RM6 Flyback Transformer is designed for compact offline switching power supply systems requiring efficient high-frequency energy transfer, reliable electrical isolation, and optimized PCB space utilization.
Built with an RM6 ferrite core structure, the transformer provides compact installation capability, stable electrical performance, and efficient magnetic characteristics for low-to-medium power SMPS applications.
Optimized for flyback converter topologies, the RM6 platform supports reliable operation under continuous high-frequency switching conditions while helping improve overall AC-DC conversion efficiency.
Its compact structure makes it suitable for embedded electronics, smart control modules, compact adapters, and space-constrained power systems.
Customized turns ratios, insulation systems, winding structures, and output specifications are available according to application requirements.
RM6 series offline flyback transformers feature vertical core and extended pins for compact layout and easy assembly. The grounded core significantly enhances EMI performance to meet strict EMC requirements. With wide 100–265V AC input, stable 40–100kHz operation, and flexible multi‑winding outputs, they are widely used in white goods, LED drivers, smart adapters, industrial controls, and metering systems—ideal for compact, high‑reliability power solutions.
