【Abstract】 This paper analyzed the relation that the capacitance,consumption and impedance of a solid tantalum electrolysis capacitor varied with the frequency. The experiment result proved that the increasing of the frequency could constantly lead to the decreasing of the capacitance and the enlarging of the consumption correspondingly. When the frequency was increased to some value, the minimum impedance could be found. Ultimately, some methods were given to improve the frequency characteristics.更多还原
