Where there are low-quality capacitors (or poor circuit design), there’s always trouble. Don’t recognise the brand? Avoid them! :) Brand reputation is one clue, but the capacitor’s series, ratings and operating conditions matter too. Heat, ripple current and operating voltage can all affect capacitor life; this video doesn’t establish which factor caused these failures.
