<p>PURPOSE:To enhance the reliability by stabilizing the electric characteristics even if a conductive bonding agent runs into the gap between a connector pin and an element within the title voltage dependent non-linear ceramic element having the capacitor characteristics and varistor characteristics for protecting the semiconductor and circuit equipment from the abnormal high voltage, noise, static electricity, etc., generated from an electric equipment. CONSTITUTION:Within the title voltage dependent non-linear resistor ceramic element, a semiconductor ceramics mainly comprising SrTiO3 having the voltage dependent non-linear resistance characteristics takes the shape wherein two coaxial cylinders in different outer peripheral diameters with the length of the cylinder in larger diameter having a cylindrical through hole in the central part of the whole cylinder while an electrode is arranged on the whole inner peripheral surface of the through hole and the outer peripheral surface excluding the specific distance from the end of the cylinder as well as the plane whereon the cylinders in large and small diameters come into contact with each other. Through these procedures, the distance between the electrodes is not to be changed even if a conductive bonding agent 5 runs into the gap between a pin 6 and an element 3 so that the bonding space may be widened thereby enabling the electric characteristics to be stabilized for enhancing the reliability upon the title element.</p> |
