The burn-in of electrolytic capacitors is an effective way to reduce its leakage current. Burn-in method is shown as the figure. In the figure, G is a regulated power supply voltage, and its maximum current is above 1.5A. P1 is DC milliammeter with above 500mA range; P2 is DC voltmeter which is sectected according burn-in voltage value. The R -limiting resistor: resistance is selected by burn-in capacitor rated working voltage with 1V taking 1Ω. If the burn-in capacitor rated voltage is greater than 100V, R take, 1kΩ, the power of resistor R should be greater than 2W, depending on the value of parallel capacitor.
