Conduct withstand voltage test for tantalum capacitor and ceramic capacitor. In order to ensure reliability, the capacitor test requires the use of a high-voltage power supply that can apply a higher voltage than the standard power supply, because the test is carried out at a voltage of 1.5 to 2 times the rated voltage to ensure reliability.
In the leakage current measurement test, the amount of current flowing when a certain voltage is applied is measured. In order to measure the leakage current, apply a high voltage using a high voltage power supply and measure the leakage current during application.
