• Due to the widespread practice of derating (operating the capacitor at 50% rated voltage) MLCC ’s are not expected to experience wearout during operation. • According to Mogilevsky and Shin (1988): where t is time, V is voltage, T is temperature (K), E a is an activation energy (~1.3) and K B is Boltzman's constant (8.62 x 10-5 eV /K)
