Abstract:
A circuit protection device (31) suitable for surface mounting on a substrate (19). The device has a laminar PTC resistive element (3) which is composed of a conductive polymer composition and is positioned between first and second electrodes (5, 7). Attached to the first electrode is a first electrical terminal (33) containing an electrically conductive material which has a first attachment portion (35) connected to a first flexible portion (39) by means of a first connection portion (47). At least part of the first flexible portion is free of attachment to the first electrode. The first attachment portion is coplanar with at least one of the first connection portion and the first flexible portion, The first attachment portion may contain a slot (49) and a solid hinge portion (51). When the device is mounted on a substrate by means of a mounting component (41) extending from the first terminal, the first flexible portion allows contraction and expansion of the conductive polymer despite the rigid attachment of the mounting component onto the substrate.
Abstract:
Electric switchgear (10) with at least one power component (12) in a fully-insulated casing (14), and provided with a heat sink (21) and connection pieces (14) emerging from the casing (14). To evacuate to the outside the heat generated in the power components (12) through the connection elements (13) the heat sink (21) is connected over a large contact surface with several connection elements (13) in order to transfer the heat, while ensuring electrical insulation. The invention can be used generally in order to dissipate heat from electrical equipment with a fully insulated casing and preferably in motor vehicles, where it is subjected to exacting requirements owing to the presence of dirt and damp.

Abstract:
Electronic devices may contain electrical systems in which electrical components are mounted on a substrate such as a printed circuit board. The electrical components may include surface mount technology components. Multiple surface mount technology components may be stacked on top of each other and beside each other to form an electrical component that minimizes the amount of area that is consumed on a printed circuit board. Noise suppression circuits and other circuits may be implemented using stacked surface mount technology components. Surface mount technology components placed on the printed circuit board may be pushed together and subsequently injection molded to form packed component groups. An integrated circuit may be mounted to the printed circuit board via an interposer and may cover components mounted to the printed circuit board. An integrated circuit may be mounted over a recessed portion of the printed circuit board on which components are mounted.
