The biggest feature of the self-healing shunt capacitor is its self-healing performance. When the dielectric breaks down, the short-circuit current will melt and evaporate the metal film around the breakdown site, thereby restoring the insulation, so it has a higher operational reliability. The self-healing time after dielectric breakdown is only a few microseconds. When the weak [...]
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 [...]
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 [...]
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 [...]
The so-called mica capacitor is a capacitor that uses natural mica as the medium of the capacitor. Its production method is to use metal foil or spray a silver layer on the mica sheet as the electrode plate. Powder or sealing made in epoxy resin. The following are the Features of mica capacitors: ①The capacity range [...]
