計算公式

L_x = L_o \cdot 5^{\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
在允許的最高工作溫度下的估計壽命（小時）
L_oSpecified lifetime (hours) at rated voltage within the maximum capacitor temperature
電容器最高溫度下施加額定電壓的規定壽命（小時）
T_oMaximum operating temperature (℃)
最高工作溫度（℃）
T_xApplication temperature (°C) of the capacitor
電容器的使用溫度 (℃)
T_nActual ambient temperature (℃)
實際環境溫度（℃）
△T_xTemperature (℃) rise of additional ripple current
附加紋波電流的溫升 (℃)
△T_oTemperature (℃) rise with additional rated ripple current
附加額定紋波電流的溫升 (℃)
I_xRipple current applied (Arms)
施加的紋波電流（Arms）
I_oRated ripple current (Arms) corrected by frequency coefficient at maximum operating temperature
在最大工作溫度時用頻率係數修正後的額定紋波電流（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.
如果需要得到更加準確的ΔTx，推薦使用熱電偶進行實測
壽命上限為15年，如需求超過15年，請與敝司聯繫
實際使用紋波電流請勿超過規格值，否則容易導致公式估算誤差大，而不具參考作用
如有超出規格值特殊需求，請與敝司聯繫
