A. Common mode choke ( Nanocrystalline core for Common mode choke )


     1.  Application:

           ¡ñ Input (DC) : Two stage common mode design , Udc = 600 ~ 1000V , Single phase , can use high ¦Ì value ultramicrocrystal magnetic core .

           ¡ñ Output (AC) : Two stage common mode design , Uac = 240/400V , Single phase, three phases can use high ¦Ì , low ¦Ì value ultramicrocrystal magnetic core.


     2.  Advantages :

          ¡ñ High ¦Ì , can reduce device volume .

           ¡ñ Compared with ferrite CMC, it can reduce more than 40% DC copper resistance Rcu, improve efficiency and better temperature characteristics.
