MTBF和生命周期之间的区别是什么？
MTBF和生命周期之间的区别是什么？
答：MTBF和生命周期都是产品可靠性的常用指标。我们遵循MIL-HDBK-217F通知2（应力分析）标准作为MTBF的计算基础。MTBF（Mean Time Between Failure）是可靠性预测的预期值，指电源在连续运行一段时间后，可靠性降至36.8%的平均时间。
生命周期是指电容器和电解在最高工作温度下的温升试验结果，用于计算电容器、电解和电源的参考寿命。
What is differential between MTBF & Life Cycle?
MTBF and Life Cycle both are common indicators of product reliability. We follow the standard of MIL-HDBK-217F Notice 2 (Stress Analysis) as the calculation base for MTBF. MTBF (Mean Time Between Failure) is the expected value of reliability prediction, which refers to the average time when the reliability of the power supply drops to 36.8% after continuous operation for a period of time.
Life Cycle refers to the result of the temperature rise test of the capacitors and electrolysis at maximum operating temperature, to calculate the reference life time of the capacitors, electrolysis and the power supply.
