According to a Reuters report in Washington on June 8, the World Bank raised its global economic growth forecast for 2021 to 5.6% on Tuesday local time, marking the strongest recovery from the recession in 80 years. According to the report, the World Bank’s latest "Global Economic Outlook" report shows that the bank’s economic outlook is 1.5% [...]
Polymer chip laminated aluminum electrolytic capacitor belong to the basic components of the electronic information industry. It is a new type of chip electronic component products that use conductive polymer materials with high conductivity as solid electrolytes. Compared with traditional liquid aluminum electrolytic capacitors, this product has many advantages such as smaller size, better performance, wide [...]
Points to note when choosing X capacitors 1. Capacitors for suppressing electromagnetic interference of power supply When capacitors are used to eliminate noise in power cross-line circuits, not only normal voltages, but also abnormal pulse voltages (such as lightning) must be considered, which may cause the capacitors to smoke or catch fire. Therefore, the safety standards [...]
Starting capacitors refer to AC electrolytic capacitors or polypropylene and polyester capacitors used to start single-phase asynchronous motors. The single-phase current flowing through a single-phase motor cannot generate a rotating magnetic field, and a capacitor is needed to separate the phases. The purpose is to make the current in the two windings produce a phase difference [...]
Five precautions for replacing capacitors Fixed capacitors are prone to failure phenomena such as leakage, short circuit, open circuit, poor contact of the internal leads of the capacitor (the pole piece and the lead connection), etc. Especially electrolytic capacitors have a much higher failure rate than other types of capacitors. The frequent failure phenomena of electrolytic [...]
