計算公式
T = T_0 \times 2^{\frac{\triangle T}{10}} \times 1.5^{\left(1-\frac{RC_1}{RC_0}\right)} \times \left(V/V_0\right)^{0.7}
  • Expected life time.
  • Actual life time.
  • Temperature difference (The highest temp. for capacitor - Actual operating temp.).
  • Actual ripple current applied.
  • Ripple current shown in our catalogue. (RC1≦RC0)
  • Rated voltage.
  • Actual voltage applied (when Vo≦0.8V, used Vo=0.8V)
  • Select the capacitors to meet the service life of a device. Please be reminded that, the result using the life calculating formula is not guaranteed.
