Testing of all pre-production items were completed. No catastrophic failures were noted during qualification testing. Post life insulation resistance measurements obtained at 200C did not all meet minimum requirements. Reduced temperature measurements of insulation resistance were satisfactory and, in fact, exceed MIL-C-11015 initial requirements for similar type capacitors. The newly developed high temperature encapsulant performed satisfactorily with no evident signs of deterioration after exposure to 200C for 2000 hours. A slight oversize condition of some units, due to problems of dip control, was recognized and should cause no further problem with the pilot run capacitors. Author
