32+32uf 500V Audio Electrolytic Double Amplifier Capacitors Dropship

Voltage: 500V After the electrolytic capacitor has been left unused for a long time (2 to 3 months), if it is immediately connected to the rated operating voltage, losses and heating will increase significantly. Therefore, an electrolytic capacitor that has been left standing for a long time needs an aging (activation) process before it can be used normally. The specific method is to increase the working voltage at both ends of the electrolytic capacitor step by step until the rated voltage. If the operating voltage of the electrolytic capacitor is 450 V, the following steps can be performed: First the capacitor is subjected to a voltage of 50 V for 10-15 minutes Then, every 4-5 minutes, the voltage is increased by 20 V and the working voltage is gradually increased. At rated voltage. For safety reasons, it is generally necessary to connect a 100K5W current-limiting resistor in series to prevent electrolytic short circuit from damaging the power supply. The voltage across the 100K resistor can also be used to detect electrolytic leakage current. If conditions permit, it is also possible to use an adjustable high-voltage power supply with a 10 mA constant current source for aging. Normally, the intact electrolytic capacitor has a leakage current of 0.025~0.05 mA/microfarad at rated voltage and normal temperature. Note: Please allow 1-3mm error due to manual measurement.
