The invention specifies a surface-mountable apparatus (100) which has a mounting face (101), an upper face (102) which is situated opposite the mounting face (101), an electrically insulating support plate (1), an electrical component (2) and a housing (3). The support plate (1) closes off the apparatus (100) with respect to the mounting face (101). The support plate (1) also has an attachment face (103) which is situated opposite the mounting face (101). In order to make electrical contact with the component (2), the support plate (1) has conductor tracks (4) which are arranged on the attachment face (103), contact areas (5) which are arranged on the mounting face (101), and apertures (6), in each case one contact area (5) being electrically conductively connected to a conductor track (4) by means of an aperture (6). The component (2) is enclosed by the housing (3), with at least one aperture (6) being arranged beneath the component (2). The housing (3) and the support plate (1) are arranged flush with one another when the support plate (1) is viewed from above. Furthermore, the housing (3) closes off the apparatus (100) with respect to the upper face (102).
