Small Switched and Pulse Transformers　

Small Switched and Pulse Transformers



Characteristics：



Manufactured with Fe-based nanocrystalline structure alloy, it is featured with high permeability, low coercive force, low losses and low temperature surge, it is possible to flexibly choose proper cores and magnetic property according to working mode of the switch.



Application：



The main transformers, pulse transformers and control transformers for various types of switch modules with medium and small power, applicable for single ended, bridge, and push-pull switches.
