What are the technical performance characteristics of electrolytic capacitor?

Today, I will talk with you. The technical performance characteristics of electrolytic capacitor mainly include the following points:

 & nbsp; & nbsp; & nbsp; Range requirements of electrolytic capacitor, rated voltage range: 6.3V-400V DC; Operating temperature range: -55 ℃~+105 ℃; Nominal capacitance range: 0.1-6800uf; Leakage current (20 ℃): 1 ≤ 0.01CrUr (uA) or 3uA, whichever is greater (2 minutes), durability:+105 ℃ Apply rated voltage for 1000 hours, and after 16 hours of recovery, the capacitor should meet the following requirements; Storage:+105 ℃, 1000 hours, after 16 hours of recovery; The initial value of the change rate of electrical capacity is within ± 30%; 2. Leakage current value ≤ initial specified value; 3. The correct value of the loss angle is ≤ ± 300% of the initial specified value

  & nbsp; & nbsp; & nbsp; Requirements for storage of electrolytic capacitor:+105 ℃, 1000 hours, after 16 hours of recovery, the capacitor needs: capacitance change rate ≤ ± 30%, within the initial value; The correct value of the loss angle is ≤ ± 300% of the initial specified value; Leakage current value ≤ 2 times the initial specified value. In addition to the requirements for storage, there is also a requirement for welding heat resistance: at 270 ℃, the capacitor should be kept on the hot plate for 30 seconds, and then removed from the hot plate and allowed to recover in a greenhouse. The capacitor needs to have a leakage current value ≤ the initial specified value; The initial value of capacitance change rate ≤ ± 10% is within; The correct value of the loss angle is ≤ the initial specified value
