摘要

A dielectric powder material, for Y5U multilayer ceramic capacitors was developed in the Pb(Mg/sub 1/3/Nb/sub 2/3/)O/sub 3/-Pb(Ni/sub 1/3/Nb/sub 2/3/)O/sub 3/-PbTiO/sub 3/ ternary system by using an alkoxide process. Multilayer ceramic chip capacitors (10 mu F) with high specific capacitances were fabricated using this powder. A Ag80%-Pd20% alloy was used for the internal electrodes. The alkoxide-derived capacitor had an extremely high specific capacitance of about 500 mu F/cm/sup 3/ and a small temperature dependence meeting Y5U specifications of the EIA standard. The equivalent series resistance was approximately 20 m Omega at 500 kHz. The breakdown voltages of the capacitor were 300 V or higher. In accelerated load life tests and load humidity tests, no degradation of insulation resistance was found during 1000 h of testing.
