1. Aluminum electrolytic capacitor is a two-polar structure (see the mark on the capacitor body). Please pay attention to the polarity when installing.Alternating current (ac) or the application of the reverse voltage may cause short circuit or a damaged capacitor circuit polarity may occur in the reverse or not sure, so the dual polarity capacitors is [...]
Here we analyze the cause of ceramic capacitor leakage current As a result, leakage of the ceramic capacitor is reduced due to insulation. The following two reasons are summarized: The first is the surface insulation degradation caused by surface contamination. Such leakage current is not very large. Generally, it is a micro-ampere level, and the [...]
Both the X safety capacitor and Y safety capacitor are safety capacitors. The difference is that the X capacitor is connected across the input line to eliminate the differential mode. The Y capacitor is connected between the input line and the ground line to eliminate common mode.The X safety capacitor uses a plastic square-shaped high-voltage CBB [...]
The capacitance value of a ceramic capacitors generally refers to the maximum/maximum value of the voltage that can be tolerated between the two electrodes of the capacitor. The pressure resistance value is generally only reached when testing, for testing the quality of ceramic capacitors. Even during the test, the withstand voltage value is maintained for a [...]
Alcoa, the world’s sixth-largest aluminium producer headquartered in Pittsburgh, Pennsylvania, USA, has begun work to restore its smelter in southwestern Indiana this summer, and has hired workers for it. The Pittsburgh-based company announced at the end of March 2016 that it would permanently shut down its Warrick Operations smelter and that it would be powerless because [...]
