<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 resistor ceramic element having the capacitor characteristics and varistor characteristics for protecting the semiconductor and circuits of equipment from abnormal high voltage, noise, static electricity, etc., generated from an electric equipment. CONSTITUTION:Within a 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 shorter than that of the cylinder in smaller diameter having a cylindrical through hole in the central part of the whole cylinder while an electrode is arranged on the whole inner peripheral surfaces of the through hole and then the other electrodes are arranged on the outer peripheral surfaces of the cylinders in smaller outer peripheral diameter. 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 connection may be facilitated to increase the bond strength thereby enabling the electric characteristics to be stabilized.</p> |
