Eurostat released the latest revised data on the 8th, showing that due to the impact of the new crown epidemic, the euro zone's gross domestic product (GDP) fell by 11.8% from the previous quarter, and the EU's GDP fell by 11.4% from the previous month. This is the largest economic decline since the EU had statistics [...]
A paper capacitor stores its charge between two metal foils separated by impregnated capacitor paper. It was the default general purpose capacitor for most of the twentieth century, and it has almost vanished from new designs, pushed out by polyester and polypropylene film parts that are smaller, more stable and cheaper to build. Knowing why it [...]

The lifetime of photovoltaic inverter is determined by the reliability of its components. Electrolytic capacitors are one of the key components to improve the reliability of photovoltaic inverters. In addition, photovoltaic inverters have high expectations for life, so there are also requirements for capacitors. Photovoltaic inverter requirements for electrolytic capacitors 1. High voltage Generally, high-power photovoltaic [...]
Variable capacitors can be divided into air dielectric variable capacitor and solid dielectric variable capacitor according to their dielectric materials. 1. Air dielectric variable capacitor The electrode of the air dielectric variable capacitor is composed of two sets of metal sheets. Among the two sets of electrodes, the fixed set is the stator, and the rotatable [...]
