How to activate electrolytic capacitors? |Focus on mid-to-high-end brand capacitor manufacturers

Leaving electrolytic capacitors for too long often affects the use effect. Activation of electrolytic capacitors when used again has also become a key factor in the service life. Large-capacity electrolytic capacitors are stored for half a year or more than one year, and they must be activated when they are used again. , Otherwise it will cause damage or life. So how do we activate the old electrolytic capacitor?　　 1. Use a multimeter to measure the electrolytic capacitor to be activated. When the forward resistance is zero or very small, it means that the electrolytic capacitor has been broken down and is scrapped. All other electrolytic capacitors can be activated.　　2. After welding the electrolytic capacitor, first add half voltage. Take a 450V electrolytic capacitor as an example, the mains voltage can be adjusted to 130V. At this time, the DC voltage at both ends of the electrolytic capacitor is about 130Vx1.4u003d180V, and it is activated for 24 hours.　　3. Then disconnect the AC power supply, and use a 5W300Ω resistor to lap the two ends of the electrolytic capacitor to discharge. Pay attention to the discharge.　　4. Use a capacitance meter to measure the recovery of the capacity. Generally, it can recover about 60%. For the capacity that has not recovered at all, it can be basically judged that the electrolytic capacitor has been broken and damaged.　　5. Adjust the voltage to 220V. At this time, the DC voltage across the electrolytic capacitor is 220Vx1.4u003d300V. Continue to activate for 24 hours. At this time, the capacity can be restored to 90% to 100%.　　6. u200bu200bAdjust the voltage to 350V. At this time, the DC voltage across the electrolytic capacitor is about 350Vx1.4u003d490V, continue to activate. 48 hours or 72 hours. There is no limit to the number of electrolytic capacitors activated each time.　　 After the above activation treatment, the electrolytic capacitor can generally be restored to the nominal capacity, and the drain electrode is small.

Given the important role played by in ensuring proper functioning of electrolytic capacitor suppliers, every individual must take an interest towards improving electrolytic capacitor suppliers.
