Abstract
Abstract An electrical circuit component including a solder preform which envelops connection terminals on the ends of an electrical circuit body of the element is disclosed. When heat is applied to the solder preform, the solder flows and electrically connects the component into an electric circuit. The solder preform has two end portions that are joined by a bar of reduced cross section which melts upon the application of heat. The solder preform also includes laterally extending flaps which embrace the side edges of the circuit element.
