Abstract
An electrical component having a functional unit which is secured to a header and which generates or is sensitive to sound, and having terminal elements which are mechanically secured to the header and electrically and acoustically coupled to the functional unit and which project through holes in the header onto the side of the header remote from the functional unit and which have a modulus of elasticity of E >50 MPa, in which the terminal elements are partially encased in a viskoelastic material having a modulus of elasticity of E <10 MPa. By encasing the terminal elements in a viskoelastic material, effective sound-damping can be produced. Furthermore, the invention relates to a process for manufacturing the component.
