Why Ceramic Capacitors Crack at 120 Hz: Piezoelectric Self-Stress
Ceramic capacitors don't crack from heat—they vibrate themselves apart. Barium titanate is piezoelectric: voltage creates physical flex, which generates new voltage, creating more vibration. At resonance, stress doubles every cycle until the ceramic fractures at 45 degrees from the termination. Every Class II capacitor (X7R, Y5V) in your devices is susceptible to this failure mode. This video uses AI-generated visuals. #electronics #MLCC #piezoelectric #capacitorfailure #engineeringfail
