Jianghai aluminum electrolytic capacitor lifespan calculation formula: Lx = L0 x 2^((T0-Tx)/10) x (V0/Vx)^n. Where L0 is rated lifespan (hours), T0 is rated temperature (usually 85C or 105C), Tx is actual working temperature, V0 is rated voltage, Vx is actual working voltage, n is voltage coefficient (usually 2-3). Example: CD139 series rated lifespan 10,000 hours at 85C, actual working temperature 65C, working voltage 400V, then expected lifespan is approximately 10,000 x 2^((85-65)/10) x (450/400)^2.5 ≈ 40,000 hours. Jianghai provides online lifespan calculation tools for quick estimation.

Use our online lifespan calculator or contact FAE for detailed lifespan analysis based on your specific operating conditions.
