Abstract
Abstract A method of making a surface mountable electronic device comprising the steps of providing a discrete electronic device comprising a body and a pair of spaced apart leads each of substantially circular cross-section and extending axially outwardly from the body in generally opposite directions, shaping each of the leads to provide a plate-like section in each of the leads at a location axially outwardly from the body, encapsulating the device body in electrical insulating material in a manner shaping the material to provide a body having first and second spaced apart ends and a mounting surface extending between the ends, the plate-like sections of the leads extending from the ends, and shaping each of the plate-like sections of the leads to have a contact portion extending along the mounting surface for making electrical connection to a circuit having a portion defined on a surface to which the device is mountable.
