As one of the important components of power system

thin film capacitor is widely used due to its such advantages as long service life and high reliability. However

there is very little research on mining the inherent properties of the capacitor from a data perspective. In order to fill this gap

40 793 thin film capacitor data are collected from the network as the analysis basis. Firstly

scatter plots and box plots are used to analyze the differences in capacitance

maximum and minimum temperatures

AC/DC operating voltages

and other factors of capacitors prepared from different materials from a horizontal perspective. Then

pie charts are used to compare the operating temperatures and application scenarios of capacitor from a vertical perspective. Finally

the Pearson coefficients of these performance indicators is calculated for correlation analysis. The results show that metallized polypropylene material

as the current mainstream material

has significant advantages over other materials in terms of capacitance and AC/DC operating voltage

while metallized polyphenylene sulfide dominates in operating temperature. The correlation between various parameters of capacitors

except temperature and operating voltage

is not significant. In the future

further data processing and learning can be carried out to achieve performance prediction results.
