Embodiment Construction

[0022] figure 1 A schematic circuit arrangement of the electrical component 10 according to the first embodiment is shown. The electrical component 10 comprises a first coil 15 and a second coil 20 which are wound around a common coil core 25 . The coil core 25 is ferromagnetic and has ferrite as raw material. Additionally or alternatively, it is conceivable for the coil core 25 to comprise neodymium as material. At the same time, other ferromagnetic materials can be considered for the coil core. In this embodiment, the coil core is designed as a rod core. Alternatively, it is also conceivable for the coil core to be configured as a C core, U core, E core, ER core, EFD core, ring core, EP core or RM core. Alternatively, it is also conceivable to omit the coil core 25 .

[0023] The first coil 15 is arranged directly adjacent to the second coil 20 on a coil core 25 . The first coil 15 has a first input 30 and a first output 35 . The first coil 15 includes a plurality of ...
