Why does a capacitor’s ESR increase even when its capacitance still appears acceptable? This article explains how heat, ripple current, electrolyte dry-out, chemical aging, and internal degradation affect ESR—and why the change can signal rising ripple voltage, power loss, and circuit instability. Understanding these failure mechanisms helps engineers and PCB repair specialists interpret ESR measurements more accurately and identify aging capacitors before they cause intermittent or catastrophic faults.
