ECS-8FA3X-250-TR是一款低损耗超小型的SMD振荡器，Mean Time Between Failure (MTBF) for MEMS is stated at 130,000 years, as compared to a quartz device stated at 30,000 years. On the surface a 4:1 ratio of improvement seems like a significant talking point until you consider most products are designed with a less than five-year life cycle. Typically, long life designs are in the ten to fifteen-year life cycle, with a very small group needing as much as twenty years. If you compare the jitter, phase noise, and temperature performance tradeoffs you lose when comparing MEMS versus quartz, you are giving up a tremendous amount of performance today so your product might last for 130,000 years. For reference: Humans have been around for 200,000 years. Civilization for a mere 6,000 years. I think we can all agree that 30,000 years is enough.

MEMS 的平均故障间隔时间 (MTBF) 为 130,000 年，而石英晶振器件为 30,000 年。从表面上看，4:1 的改进比例似乎是一个重要的话题，直到您考虑到大多数产品的设计生命周期不到五年。通常，长寿命设计的生命周期为 10 到 15 年，极少数设计需要长达 20 年。如果您比较在比较 MEMS 和石英时失去的抖动、相位噪声和温度性能折衷，那么您今天就放弃了大量的性能，因此您的产品可能会持续 130,000 年。供参考：人类已经存在了20万年。文明只有6000年。我想我们都同意三万年就足够了。
