Surface mounting discharge tube has soldering tapers formed at peripheral edges of electrode side surfaces that seal and project outwardly from opposite ends of cylindrical ceramic envelope

US-7719174-B2

Abstract

A surface mounting discharge tube, comprise of a cylindrical ceramic envelope sealed at its two ends by side surfaces of electrodes, designed to be directly soldered on to a mounting board, where the electrodes at the two ends are rectangular, project outward radially at the ends of the ceramic envelope and are provided at peripheral edges at the side surfaces of the electrodes with soldering use tapers or step differences, whereby positional deviation at the time of soldering is suppressed and sufficient PCT properties are secured.
