TDK Corp. has introduced a new series of multilayer ceramic capacitors that provide extended life performance and meet electrical, mechanical, and environmental standards from multiple industry specifications, including automotive and higher grades.
The new CGJ series is best suited for applications that require field life such as smart meter, smart grid, solar inverters and charging stations, or higher reliability applications in the medical, industrial and automotive markets.
Mass production of the new series has already begun and production volumes are available now.
The new CGJ series is available in C0G & X7R temperature characteristics and standard JIS/EIA case sizes of C1005/0402, C1608/0603, C2012/0805 and C3216/1206. This extended life series capacitor was made possible by using TDK's expertise in dielectric materials coupled with extensive testing during the manufacturing process and guarantees 2000hr life at 2x rated voltage.

2000hr does not seem like a lot but I suspect that is because the 2X rated voltage. Is this a meaningful way of specifying the rated life? It would seem a better way would be .5 rated V at 25 degrees C or max. rated temperature.
It is also interesting that no temperature is mentioned, I assume that mean 25 degree C but it would be better to include that data point.
