计算公式

L_x = L_o \cdot 10^{\wedge}\left(\frac{T_o - T_x}{20}\right) \\ \text{where } T_x = T_n + \triangle T_x, \quad \triangle T_x = \triangle T_o \times \left(\frac{I_x}{I_o}\right)^2

L_xEstimated lifetime period (hours) at maximum operating temperature allowed
在允许的最高工作温度下的估计寿命（小时）
L_oSpecified lifetime (hours) at rated voltage within the maximum capacitor temperature
电容器最高温度下施加额定电压的规定寿命（小时）
T_oMaximum operating temperature (℃)
最高工作温度（℃）
T_xApplication temperature (°C) of the capacitor
电容器的使用温度 (℃)
T_nActual ambient temperature (℃)
实际环境温度（℃）
△T_xTemperature (℃) rise of additional ripple current
附加纹波电流的温升 (℃)
△T_oTemperature (℃) rise with additional rated ripple current
附加额定纹波电流的温升 (℃)
I_xRipple current applied (Arms)
施加的纹波电流（Arms）
I_oRated ripple current (Arms) corrected by frequency coefficient at maximum operating temperature
在最大工作温度时用频率系数修正后的额定纹波电流（Arms）
NoteIf a more accurate Δ Tx is required, it is recommended to use a thermocouple for actual measurement.
The maximum lifespan is 15 years. If the demand exceeds 15 years, please contact our company.
The actual applied ripple current shall not exceed the specification value, otherwise the formula estimation error is easy to be large and without reference value.
If there are special requirements beyond the specification value, please contact our company.
如果需要得到更加准确的ΔTx，推荐使用热电偶进行实测
寿命上限为15年，如需求超过15年，请与敝司联系
实际使用纹波电流请勿超过规格值，否则容易导致公式估算误差大，而不具参考作用
如有超出规格值特殊需求，请与敝司联系
