The relationship between the rated working voltage of the axial film capacitor and the breakdown voltage test voltage|Focus on the manufacturer of high-end brand capacitors

To talk about the relationship between the rated working voltage, breakdown voltage, and test voltage of axial film capacitors, it is natural to know the definition of these three. The so-called rated working voltage of the axial film capacitor refers to the voltage applied to both ends of the capacitor that the capacitor can work normally within a certain time range. The test voltage refers to the appropriate test voltage selected in order to ensure the quality of the axial film capacitor and eliminate the obvious defects in the product or the product with low breakdown voltage. Breakdown voltage refers to the ultimate voltage that axial film capacitors can withstand. Testing the breakdown voltage is a destructive experiment. Generally speaking, the ratio of the breakdown voltage of the axial film capacitor to the rated operating voltage depends on the design and manufacturing process of the capacitor. The design and manufacturing process are different, and the safety factor of the product is different, and the ratio of the breakdown voltage to the rated voltage is also different. The selection of the test voltage for the axial film capacitor should be appropriate. If it is too large, it may damage the capacitor, cause hidden dangers, and reduce reliability. If it is too small, it can't eliminate the obvious defect or the capacitor with too small breakdown voltage. For axial film capacitors, the test voltage is generally 1.4 to 1.6 times the rated working voltage. The test voltage selected in this range is more appropriate.
