Multi-layer circuit structure has component(s) on multi-layer arrangement, inductance(s) formed by magnetic core, coil with all windings formed on and/or in multi-layer arrangement

摘要

The device has at least one component (5) mounted on the multi-layer arrangement (2) and at least one inductance (7-9) formed by a coil and a magnetic core (1), whereby all the windings of the coil are formed on and/or in the multi-layer arrangement. The device forms a filter for high bandwidth data transmission, e.g. an ADSL for a telephone connection.
