TRANSFORMER AND POWER MODULE USING THE SAME

摘要

PURPOSE: A transformer and a power module are provided to increase an insulating nature between coils by using a multiple insulating wire for one or both of a primary coil and a secondary coil. CONSTITUTION: A winding unit includes one or more winding spaces. A plurality of coils (50) are laminated on an outer surface of a body. A terminal combination unit (20) is expanded from an end of the winding unit in an external diameter direction. An end of the terminal combination unit is combined with a plurality of external connection terminals (30). The width of the winding unit is smaller than the diameter of the body.
