Working medium of aluminum electrolytic capacitors(1) the working medium ofaluminum electrolytic capacitorsis to form an extremely thin aluminium oxide layer (AL2O3) on the surface of aluminum foil by anodic oxidation. The oxide medium layer and ...VIEW MORE
Usage method1. DC aluminium electrolytic capacitors should be used with correct polarity when DC aluminium electrolytic capacitors are connected to the circuit with reverse polarity, the capacitor will cause an electronic circuit short-circuit ...VIEW MORE
Installation ofaluminum electrolytic capacitors1. Used capacitors can not be used again, but can be removed as a periodic
check to test electrical performance;
2. If the capacitor is charged, use a resistance discharge of about...
(1) The capacitance per unit volume is particularly large.The lower the working voltage, the more prominent this feature, therefore, especially suitable for the small capacitor and large capacity. For example, the specific capacity of CD26 type l...VIEW MORE
(1) Poor insulation performance.It can be saidthat aluminium electrolytic capacitorsare the worst insulated of all types of capacitors. For aluminum electrolytic capacitors, the leakage current is usually used to characterize the insulation perfo...VIEW MORE
1、 Lower the ambient temperature lower the ambient temperatureSo that the capacitor does not work under the upper-limit class temperature, in addition to taking into account the capacitor itself heating effect, this is particularly important for ...VIEW MORE
Aluminum electrolytic capacitorrated capacity with the preferred number of series E 6, that is: (n = 0,1,2.5) ; a total of 6 values: 1uF, 1.5uF,2.2uF,3.3uF, 4.7uF, 6.8uF.
The allowed deviation is ± 20% for series E 6, but for general pur...
In the 1980s, when LSI and VLSI were booming, some people were extremely pessimistic about the future of capacitors, and it turned out that, such arguments smack of alarmism: the industry has grown at an average annual rate of more than 20 per ...VIEW MORE
1, Aluminum electrolytic capacitor life by the use of conditions is very largeSuch as the use of temperature, humidity, vibration, added voltage, ripple and so on. The failure rate (λ) ofaluminum electrolytic capacitorsis shown in the diagram b...VIEW MORE
