Murata's General MLCC products are designed for use in devices with a typical lifetime around 10 years. Murata's general MLCC products are designed so that the estimated useful life can be extended longer than 10 years under the following conditions: "80% of the rated voltage or less, Maximum operating temperature -20°C or less" The estimated useful life under actual operating conditions can be approximated from the chart.

  • *Please consider using general product for equipment that requires longer useful life than consumer equipment, such as industrial equipment, medical devices excluding implants, and automotive infotainment / comfort devices.
  • *The estimated useful life is the time when the cumulative failure rate of continuous use is 1%.
  • *The estimated useful life data is provided for reference only. Please use it as a rough estimate when designing and using devices. The data is not intended as a guarantee of the product lifetime.
