Embodiment Construction

[0018] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0019] A non-solid tantalum capacitor aging method, comprising the following steps:

[0020] (1) According to the relationship between the applied voltage value of the capacitor and the temperature: V 低 / V 高 =T 高 / T 低 , to calculate the rate relationship between the applied voltage value at different temperatures and the applied voltage value at room temperature; for example, at 85°C, V 低 / V 高 =(85+273) / (20+273)=1.22; at 125°C, V 低 / V 高 =(125+273) / (20+273)=1.35;

[0021] where: V 低 = Voltage value at low temperature (room temperature); V 高 = voltage value at high temperature; T 高 = temperature value at high temperature (absolute temperature); T 低 = Temperature value (absolute temperature) at low temperature (room temperature).

[0022] (2) The rated voltage U of the capacitor R As the applied voltage at room temperatur...

Abstract

The invention provides a non-solid tantalum capacitor aging method, comprising the following steps: (1) calculating the ratio relationship between the applied voltage value at different temperatures and the applied voltage value at room temperature; (2) according to the step ( 1) Calculate the voltage value that the product needs to apply at different temperatures from the middle ratio; (3) Aging the capacitor. The present invention can greatly reduce the leakage current of highly difficult non-solid tantalum electrolytic capacitors after aging, solve the problems of poor product stability after aging and large leakage current that lead to low qualified rate of finished products, and improve product stability, reliability and qualified rate of finished products ;By applying different voltages for aging, the existing aging time is shortened, which not only achieves the purpose of aging, but also ensures reliability and life, ensures that tantalum capacitors can work stably for a long time, and improves the performance of capacitors service life.

Description

technical field [0001] The invention belongs to the technical field of capacitors, and in particular relates to an aging method for non-solid tantalum capacitors. Background technique [0002] As a common electronic component, electrolytic capacitors are widely used in communications, aerospace and military industries, submarine cables and advanced electronic devices, consumer appliances, televisions, etc. equal effect. With the development and deepening of the industrial revolution, new requirements have been put forward for components. As an important part of components, capacitors also need to be continuously improved and updated. Now they are mainly towards light weight, miniaturization, high voltage, large The development in the direction of capacity and so on requires that on the basis of the original, the product volume is smaller, the voltage is higher, the capacity is larger, and the difficulty of the product is greatly increased, which poses new challenges to the ...
