A bobbin for a concentrically wound transformer, preferably a signal transformer, has a core, an area between two shoulders for a primary winding and an area between two flanges for a secondary winding surrounding the primary winding. The shoulder at the end of the transformer where the entry and exit wires for the primary winding are located is formed with an angled axial slot, and with undercut regions beneath the upper surface of the shoulder. The entry and exit wires pass through this undercut region and are thus isolated from the turns of the secondary winding. One lateral edge of the slot and the corresponding lateral edge of the undercut region diverge from one another in the direction of the bobbin end. Also disclosed is a housing for an electronic component, the housing having a set of walls for surrounding the component and lugs past which the component can snap to retain the component in the housing.
