計算公式
L_x = L_r \times 2^{\frac{(T_o-T_x)}{10}} \times 2^{\frac{-\triangle T_x}{5}} \times \left(V_0 / V_x\right)^{4.4} {\scriptsize  (for ≧160wv)} \\ where \triangle Tx=\triangle T₀(Ix / I₀)²
  • Expected ripple life period (hrs) at maximum operating temperature allowed (實際使用條件下的推算壽命)
  • Expected life period (hrs) at actual operating temperature 在允許的最高使用溫度,印加額定電壓(DC)及額定紋波電流(AC) 之保証壽命
  • Maximum operating temperature (℃) allowed 允許的最高使用溫度(℃)
  • Actual operating ambient temperature (℃),calculate as 40℃ under 40℃ 。 實際使用的環境溫度(℃),低于40℃以40℃計算
  • Actual applied ripple current (mArms) at operating frequency f0 (Hz) 工作頻率 f0 (Hz) 下實際印加的濾波電流(mArms)
  • Rated maximum permissible ripple current IR(mArms) x frequency
    multiplier (Cf) at f0 (Hz) 額定紋波電流(如目錄標示值),如果在不同使用頻率時,需乘以補 正系數
    ※Ripple Current calculation: no need Temperature Multiplying Factor 濾波電流計算:不需溫度乘以因數
    ※For Ripple life,Ix Should be 80% equal or more of Io,if less than 80%,
    calculate with 80%. 紋波電流應該大于或者等于Io的80%,如果小於80%以80%計算
  • ≦5℃Maximum temperature rise (℃) for applying I0 (mArms) 印加額定紋波電流時,電容所允許的溫升(小于或等于5℃)
  • Rated voltage(V) 額定工作電壓
  • Actual applied voltage(V),Vx Should be 80% equal or more of Vo 實際使用時印加在電容上的電壓,當Vx小於V0的80%時以80%計之
  • The estimated life is limited to 15 years, if it exceeds 15 years, take 15 years as standard. 推算壽命以15年為上限,超過15年的以15年計之
