A fixed capacitance is a capacitor with a fixed capacitance. The deviation of the actual capacitance of the capacitor from the nominal capacitance is called the error, and the tolerance is called the accuracy.Selection method of fixed capacitor: (1) Choose the model reasonably according to the requirements of the circuit Generally used in low frequency coupling [...]
World Trade Organization (WTO) released the latest issue global trade in goods the trend assessment report "Barometer of Trade in Goods" pointed out that in the second quarter of 2020, global trade in goods has experienced a historical decline, but other indicators show that global trade in goods and output will partially rise in the third [...]
What is a SMD aluminum electrolytic capacitor? As well as liquid and solid SMD aluminum electrolytic capacitor, the cathode material is electrolyte, non-polar and polarized, this is also the most widely used capacitor we see. Liquid aluminum electrolytic capacitor 1 Standard product RVT series φ4*5.4, φ5*5.4, φ6.3*5.4, φ6.3*7.7, φ8*10.5, φ10*10.5 -55℃～+105℃ 2000 hours 6.3V~100V 0.47uf～1500uf GPS [...]
"Election nightmare": the loser may refuse to admit defeat, fearing turmoil What to do if there is such a "nightmare": After voting on November 3, the two candidates got the same vote rate, and refused to admit defeat on the grounds of fraud and manipulation in the election. Supporters from both sides took to the streets [...]
The basic principle of supercapacitors is the same as other types of electric double-layer capacitors. They all use the electric double-layer structure composed of activated carbon porous electrodes and electrolyte to obtain a large capacity. The advantages of super capacitors have the following points: 1. A farad-level capacitance in a small volume; 2. No special charging [...]
