100% of our 947D DC Link capacitors are conditioned at accelerated temperature and voltage before they leave the factory. We've demonstrated that this process eliminates infant mortal failures and produces the most thermally and electrically stable DC Link Capacitors available today. If that's the kind of reliability you're looking for, trust the one company where it's burned in. Call for samples with thermocouples. www.cde.com | 508-996-8561http://www.cde.com
