abstract = "An EMI suppression capacitor (polypropylene film type) failed by 'popcorning' due to vapor outgassing in the pulse powered humidity-freeze cycles. No shorts or shunts could be detected despite mildly corroded metallization visible in the failed capacitor. Humidity-freeze cycling is optimized to break into moisture barriers. However, further studies will done on additional MLPE devices to optimize the stress testing for condensation to precipitate any weakness to short circuiting and other humidity/bias failure modes.",
