CHIP TANTALUM SOLID ELECTROLYTIC CAPACITOR

PURPOSE:To absorb mechanical stress, preventing a capacitor device from being damaged by a method wherein a neck of specific width is provided at a crank between the capacitor device and a cathode outer terminal. CONSTITUTION:A tantalum capacitor device 1 provided with a tantalum lead line 2 of a line diameter of 0.2 to 0.3mm is connected to metal plate terminals 3, 4 as thick as 0.1 to 0.15mm consisting of nickel, iron, iron-nickel alloy, stainless or copper alloy. When the device 1 is coated with resin, a neck having width of 0.15 to 0.6mm is provided at a crank 5 between the capacitor device 1 and the cathode outer terminal 4. It is because pressure for clamping is applied to a metal terminal to make it extend when the device is set in a high temperature mold, and this force is applied to the capacitor device 1 that the capacitor device 1 is applied with stress mechanically and physically during process of resin coating. Therefore, a point (neck) which is much weaker mechanically and physically than the capacitor device 1 is provided so that this point absorbs said force.
