MULTILAYER CERAMIC CAPACITOR AND METHOD FOR CONTROLLING EQUIVALENT SERIES RESISTANCE

摘要

Disclosed is a preferable structure for an external electrode which is used in a multilayer ceramic capacitor and also serves as a resistor element. The external electrode having such a structure is not reduced even by firing in a reducing atmosphere, thereby allowing an internal electrode to use Ni or a Ni alloy, and realizes good electrical connection with the internal electrode. Specifically disclosed are external electrodes (6, 7) formed on the outer surface of a capacitor main body (2) which respectively have a structure comprising a conductive layer (8) and a metal plating layer (9) formed on the conductive layer (8). The conductive layer (8) has a composition containing a glass component and a complex oxide such as an In-Sn complex oxide that is reactive with Ni or a Ni alloy. ® KIPO & WIPO 2009
