计算公式

L_x = L_r \times 2^{\frac{(T_o-T_x)}{10}} \times 2^{\frac{(\triangle T_o-\triangle T_x)}{5}} \\ where \triangle Tx=\triangle T₀(Ix / I₀)²

L_rExpected ripple life period (hrs) at maximum operating temperature allowed 在允许的最高使用温度，印加额定电压(DC)及额定纹波电流（AC）之保证寿命
L_xExpected life period (hrs) at actual operating temperature实际使用条件下的推算寿命
T_oMaximum operating temperature (℃) allowed 允许的最高使用温度(℃)
T_xActual operating ambient temperature (℃)，calculate as 40℃ under 40℃ 。实际使用的环境温度（℃），低于40℃以40℃计算
I_xActual applied ripple current (mArms) at operating frequency f0 (Hz) 工作频率 f0 (Hz) 下实际印加的滤波电流（mArms）
I_oRated maximum permissible ripple current IR(mArms) x frequency
multiplier (Cf) at f0 (Hz) 额定纹波电流（如目录标示值），如果在不同使用频率时，需乘以补正系数
※Ripple Current calculation: no need Temperature Multiplying Factor 滤波电流计算：不需温度乘以因数
※For Ripple life，Ix Should be 80% equal or more of Io,if less than 80%,
calculate with 80%. 纹波电流应该大于或者等于Io的80%，如果小于80%以80%计算
△T_o≦5℃= Maximum temperature rise (℃) for applying I0 (mArms) 印加额定纹波电流时，电容所允许的温升（小于或等于5℃）
NoteThe estimated life is limited to 15 years, if it exceeds 15 years, take 15 years as standard. 推算寿命以15年为上限，超过15年的以15年计之
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. 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.
