Detailed specification based on CECC 32 101-801 Climatic category (IEC 60 068) 55/125/56 DESCRIPTION The capacitor consists of a rectangular block of ceramic dielectric in which a number of interleaved nickel electrodes are contained. This structure gives rise to a high capacitance per unit terminations volume. The inner electrodes are connected to the two copper terminations, coated with a barrier layer of plated electrodes nickel and finally covered with a layer of plated tin (NiSn). A cross section of the structure is shown in Fig.1. MLB457 ceramic material Fig.1 Construction of a ceramic multilayer capacitor. 2005 Aug 17 Rev. 9 2 www.yageo.com
