← ScienceWhich outcome occurs when rapid discharge exceeds capacitor's ESR limit?
A)Thermal runaway and device failure✓
B)Increased dielectric constant stability
C)Optimized ripple current absorption
D)Enhanced equivalent series inductance (ESL)
💡 Explanation
Thermal runaway causing failure is caused by excessive heat generated from high currents through the Equivalent Series Resistance; because the dissipation exceeds the cooling capacity, positive thermal feedback occurs, therefore, thermal runaway rather than improved ripple absorption occurs, even at design ESL.
