The bad cap scourge has made it to some fluorescent fixtures here. Have been through it with LCD monitors and some TV gear. :-( Anyway this is a capacitor question. Google not very clear. CD268 and 40/105/21 come up in searches but I can't find a place where it i= s defined. http://www.feas.de/en/index.php?Itemid=3D258&id=3D211&option=3Dcom_content&= task=3Dview "The usability of components in various climates is defined by the climatic= category according to IEC 60068-1, annex A. It is made up of three paramet= ers separated by slashes. These parameters represent the stress temperature= for the tests with cold, with dry heat and with the duration in days of th= e stress with steady-state damp heat." A quick look through a couple drawers of caps and I don't see any this mark= ing.
