The high overload characteristics of military capacitors in the radio fuze is an issue of great significance.The dynamic testing of the military capacitor characteristics under high overload provides a reliable basis for systematic research on the high overload characteristics of fuzes.In this paper,a dynamic testing for a military capacitor under high overload condition is designed and experimented based on the working environment of the military capacitor in the radiao fuze.Based on the experiment,the parametric variation and failure mode of the military capacitors under high overload are discussed,and the influence of the capacitor parametric variation and failure on the fuze is analyzed.
