Definitions
- Inductive components can be used, for example, as chokes,
- Transmitter or transformers be designed or as an inductance part of electrical circuits.
- Protective components can be used in electrical circuits, in particular in the low-voltage range, in interference-sensitive lines of communication and information technology and in sensitive electronic components. With these it is possible to make unacceptably high currents or voltages harmless and dissipate them to mass or convert them into heat energy. This makes it possible to protect the components against inadmissible heating, which can cause at least a malfunction of the component function, and in extreme cases against destruction.
- protective components are used as separate components and soldered, for example, to boards.
- each soldered component requires a given electrical creepage distance, for which a certain amount of free space to the adjacent component must be maintained.
- Automatically populated boards also require a certain amount of free space between individual components, so that the placement machine can safely set down the component or, if necessary, also protect it. who can grab. Overall, this leads to a high space requirement on boards, which goes beyond the sum of the component dimensions themselves - Not least for this reason, therefore, many seeks to unite different device functions on modules, on the one hand to improve performance and on the other hand Save space on the board.

- it may have a ceramic component body which has at least two electrodes arranged on opposite main surfaces of the component body.
- Block-shaped component bodies have the advantage that they can be arranged as a plurality of extremely space-saving, in particular also in connection with other rectangular in cross-section other components or Bauelementk ⁇ r- pern of other protective devices.
- the bobbin also has side surfaces which follow a rectangle at least at three edges. The fourth upper edge of the side surface of an inductive component may follow the winding, which is usually guided via a round winding body, and may also be rounded, for example. It is therefore advantageous that
- the protective component can be designed, for example, as a PTC resistor and protects the inductive component against excessive currents. Zen.
- a polyswitch is also well suited as a protective component and is characterized by a forward behavior, which is even lower resistance compared to the PTC resistor. At high currents, the polyswitch also becomes high-impedance and blocks.
- the protective component not only for the protection of the inductive component, but for the protection of circuits, components and devices which are electrically connected to the inductive component and / or the protective component.
- the size of the protective component required for the protective function of the protective component is of the same order of magnitude as that of the inductive component. In this way succeeds the relatively largest
- Another space gain on the board on which the inventive component is equipped succeeds with an arrangement of the protective device in the context of the outer dimensions of the inductive component, consisting of bobbin, winding and magnetic core, which ensures only the complete component function of the inductive component.

- the bobbin has at least one second winding, via which a second current path is defined.
- the second current path can be protected with a further second protective device, which is then also attached to the bobbin.
- the two windings can be arranged one above the other electrically insulated. However, it is also possible to arrange the two windings next to one another on the bobbin. Accordingly, the protective components can be arranged side by side, for example below each one winding.
- the bobbin may have downwardly open chambers, wherein per winding preferably one chamber is provided in each case.
- a ceramic protective device can be inserted into the chambers, wherein the interior of the chamber is preferably adapted to the outer dimensions of the Schutzbauele element.

If the bobbin has a base following the outer dimensions of the EP core, then there is sufficient volume to arrange a number of protective components corresponding to the number of windings within the base.
- the protective components then preferably have the shape of flat cuboids and are preferably geometrically so in
- the cuboid protective components can also be arranged transversely to the main axis of the bobbin, which corresponds to the magnetic axis and thus follows the center of the EP core.
- each winding is arranged in a winding chamber, which is bounded on both sides transversely to said main axis by flanges, which continue downwards into the base.

- An inductive component with two or more windings may be formed as a transformer, wherein the windings may differ by the number of their turns.
- a transformer can be provided with different protective components for different windings.
- the windings can also be the same, so that the two coils of the finished component have the same inductance values.
- the protective components are preferably the same, so that a total of a component with high symmetry is obtained.
- An inductive component with two windings, which are connected to a magnetic EP core and two PTC resistors or Polyswitches as protective components, can be advantageously used in a low-pass filter, which separates the voice signal from the ADSL line on the one hand and on the other hand protects high currents.
- the high symmetry is used, which can be achieved with the inventive combination of inductive component and protective component in order to obtain the signal symmetry in the two current paths of the ADSL line.

- the winding body has a core hole KL, in which a magnetic core, for example, the center piece of an E-core and in particular an EP core can be inserted to complete the inductive component.
- the protective component completely takes up the space between the two flanges in the base SO and preferably closes with the bottom edge of the base and the end face of the base.
- the bobbin may also have at least one of the underside, front or back a cross brace that connects the two flanges and the protective device SB fixed in position. Preferably, however, at least one side is open to allow easy installation of the protective device SB in the bobbin SK.
