摘要:
The invention relates to an electric multi-layered component comprising ceramic dielectric layers which are stacked on top of each other between which component structures are arranged. The aim of the invention is to increase the mechanical stability, in particular soldering contact, on the component. As a result, an improved transversal form for transversal contacts is provided. Said transversal contacts have a transversal cross section which expands towards the top, at least partially, from the soldering contact to the lower side of the component.
摘要:
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.
摘要:
A monolithic resistor is provided with a central resistive metallic foil strip positioned between and attached to a pair of wings formed from an electrically conductive metallic foil. The wings include large surface areas to dissipate heat. A plurality of terminal pins are formed in the conductive strips for connection to an integrated circuit board, as well as a current source.
摘要:
Bei einem Verfahren zur Befestigung eines Kontaktelements (5, 6) bei einem elektrischen Bauteil (1) wird ein Kontaktelement (5, 6) an einer Kontaktfläche (3, 4) eines Grundkörper (2) des Bauteils (1) angeordnet und ein Laserstrahls (18) auf einen Bereich (16, 17) das Kontaktelements (5, 6) derart gerichtet, dass der Grundkörper (2) nicht in Strahlrichtung (24) des Laserstrahls (18) liegt. Durch den Laserstrahl (18) wird das Kontaktelement (5, 6) teilweise geschmolzen, so dass das geschmolzene Material (7, 8) die Kontaktfläche (3, 4) benetzt und eine Befestigung des Kontaktelements (5, 6) an der Kontaktfläche (3, 4) herstellt.
