Abstract:
A method for screening electrolytic capacitors places a capacitor in series with a resistor in series with a resistor, applying a test voltage and following the charge curve for the capacitor. A high voltage drop indicates high reliability and a low voltage drop is used to reject the piece. The leakage current is not adversely affected during the test.
