    Abstract: The invention relates to an OFW component working with acoustic surface waves. Said component comprises a chip (1), a piezoelectric substrate (1a), electrically conductive structures (2, 3, 4) arranged on the substrate and a base plate (15) with external electrical connections lines which are in contact with the electrical conductive structures of the chip (1). A protective film (5, 6) is applied on the surface of the chip supporting the electrically conductive structures (2, 3, 4), which has electrical contact elements (7, 11) on the surface opposite to their piezoelectric substrate (1a). Said elements are connected directly to the structures (2, 3, 4) of the chip (1) by through contacts (8) in the protective film (5, 6) and/or through bumps (10) and to the electrical connection elements of the base plate (15) using SMT technology.
