Lifespan of compensation capacitors

How to calculate lifespan of film capacitor?

Below is the formula for calculations of lifespan of film capacitors. Le = Ll x (Vr/Va)⁷ x 2ˣ Where; Le = Expected lifespan of film capacitor in the application. Ll = Load lifespan rating of film capacitor. X = (Tm – Ta – ΔT)/10 ΔT = I² x ESR / (B x A) Tm = Film capacitor’s maximum temperature rating. Ta = Ambient temperature of the application.

How to calculate lifespan of ceramic capacitor?

Below is the formula for calculations of lifespan of ceramic capacitors. Le = Ll x (Vr/Va)³ x (Tm/Ta)⁸ Where; Le = Expected lifespan of ceramic capacitor in the application. Ll = Load lifespan rating of ceramic capacitor. Tm = Ceramic capacitor’s maximum temperature rating. Ta = Ambient temperature of the application.

How long does a capacitor last at 95°C?

The calculation result of Eq. 13 shows that the lifetime L95 at a temperature of 95°C is estimated to be approximately twice that of L105 at 105°C. This means that 'for every 10°C decrease in operating temperature, the life of the capacitor is doubled.

What is the operational life of an aluminum electrolytic capacitor?

The operational lifetime of an aluminum electrolytic capacitor is directly related to temperature. This brief presents a simplified method of calculating a capacitor’s operational life based on temperature and operating voltage.

How does temperature affect the life of a capacitor?

Among these factors, temperature and voltage have a significant effect on capacitor life. Therefore, proper derating condition of temperature and voltage make possible capacitor’s lifetime extend. The inverse of the failure rate is the life expectancy. Lifetime estimation formulas are used to predict the lifetime of capacitors.

How to calculate lifespan of Axial electrolytic capacitor?

Below is the formula for calculations of lifespan of axial electrolytic capacitors. Le = Ll x 2ˣ Where; Le = Expected lifespan of axial electrolytic capacitor in the application. Ll = Load lifespan rating of axial electrolytic capacitor. X = (Tm – Ta – ΔT)/10 ΔT = I² x ESR / (B x A) Tm = Axial electrolytic capacitor’s maximum temperature rating.
