"Multiple customer cases highlight the critical importance of capacitor selection in SMPS output stages: (1) A customer procures 1210 100V 2.2µF MLCCs for switching power supply output filtering, (2) A separate case reported a 1210 100V 2.2µF capacitor exploding on the output filter — underscoring that ripple current rating and voltage derating are equally critical as capacitance value. (3) A customer reported a 1206 104/100V output capacitor short-circuit in an LED driver, resolved by upgrading to 250V rated parts."
