← ScienceWhich risk increases when high voltage electrolytic capacitor terminals corrode?
A)Increased equivalent series resistance (ESR)✓
B)Elevated effective series inductance (ESL)
C)Decreased ripple current handling
D)Diminished thermal conductivity to heatsink
💡 Explanation
Increased ESR occurs because aluminum oxide reduction via galvanic corrosion creates a resistive layer at the contact points utilizing ion migration. Increased ESR contributes self-heating, therefore it limits current handling capacity and stability, rather than elevated ESL or lowered thermal conductance.
