Abstract: A housing of an electronic component with an integrated cooling body is provided. The cup base of the housing is formed as a cooling body. The cooling body and the housing cup are formed integrally by an extrusion method.

Abstract: A switchable gradient coil arrangement for a magnetic resonance tomography apparatus, has conductor ends in the primary plane (or planes) that can be differently connected to one another and/or to conductor ends in the secondary plane (or planes) to form respective coil arrangements having different field qualities/performance features. The connections are produced by a switch system composed of standard switches for the logical interconnection of the individual sub-coils, in the form of at least four bipolar switches. One of these switches, as a power connection switch connects the ends of each sub-coil to the power terminals, one switch is connected parallel to the sub-coil, and at least one switch is arranged in a connection branch that branches for optional connection to other sub-coils.
