Abstract: A method of making a SAW component has electrically conductive structures on a substrate. A cap cover encapsulates and seals the structures against environmental influences. An RF shield is placed on the cap cover. The RF shield is a metallization formed of a material layer sequence of TiW, Cu or Ni and Au which is then reinforced with current-less or galvanic deposition.

Abstract: An electrical component is installed in a plastic cup. The component has two electrical connecting lines, and a parting location that is bridged by a solder metal is arranged in one lead. In addition, a prestressed spring is arranged at the one lead for removing the lead from the parting location during melting of the solder metal as a result of an overload, so that the component is disconnected from a current source. The one lead is pinched to a thickness of 0.2-0.5 mm.

Abstract: A piezo actuator (1) is disclosed that has a contact lug (20, 21) for the electrical contacting of an electrode (14, 15) of an actuator member (11). Due to an expansion and contraction of the actuator member, a mechanical stress occurs in the contact lug that is minimized in that the contact lug has a device for adapting the expanse to a dimension of the expansion and contraction. The device is, for example, a deformation material in the form of a wire weave. The piezo actuator is utilized for the drive of an injection valve in an internal combustion engine.

Abstract: An electrical component is installed in a metallic housing having a planar housing floor, in which the housing is pressed against a heat dissipation plate by means of screwable tension elements that are situated adjacent the housing wall. The tension elements have peaks at a portion that faces the housing wall.

Perpendicularly residing clips (7) are located on the system carrier, whereby the coil core (1) is arranged within the space formed by the clips. The terminals are thereby located essentially outside the space existing between the end face planes of the coil core (1).

The thermal fuse, which consists of low-melting point metal, is provided directly next to a critical element of the electrical device, such as a PTC thermistor, is preferably of U-shaped or V-shaped design, and is arranged such that its vertex is directly next to the critical element.

Abstract: A regenerable electric capacitor having wound-on layers of plastic foils provided with metal layers of the coatings. The metal layers consist of an alloy and include a variable thickness perpendicular to the longitudinal direction of the foils. As such, the thickness of the metal layers is smallest in the regions bordering metal-free edge strips and it increases towards the opposite side of the foil. In addition, the metal layers have an alloy composition that is different dependent transverse to the direction of run of the foils.
