Abstract: In this paper is Graphite material Tantalum electrolytic capacitors The manganese dioxide cathode layer Coating use as background Respectively discuss Different graphite solid content of the sample data capacity contrast Curing temperature,etc.Under the experimental conditions Graphite material Tantalum electrolytic capacitors Electrical parameters of the contrast between the impact The test results show that:Graphite solids content 5.0±X%、Curing temperature为165±y℃/45min is Graphite as the cathode material used in the top coating process conditions Sample electrical parameters improved significantly And the use of the process as a cathode material The graphite solution PH value size is very important and Affect Tremendous PH value of about 11 to 13 use the ideal parameters
