When is the lifespan of multilayer ceramic capacitors? Basic knowledge materials are being provided.
Recovery by heating for 1 to 4 hours above the Curie temperature! A clear explanation of lifespan estimation.
The parameter to pay attention to regarding MLCC failures is capacitance. MLCCs tend to degrade in capacitance during use according to equation (3-36). This aging change is due to the ferroelectricity of the ceramic and the volumetric response associated with cooling from the Curie temperature. It is also known that the capacitance of MLCCs can recover by heating above the Curie temperature for 1 to 4 hours. This document includes not only the lifespan of representative capacitors but also information on how to choose and use them, as well as the basics of capacitors.
