Marking Methods of Capacitor's Main Parameters

There are three ways to mark the main parameters of capacitor: direct mark, digital mark and color mark. 1. Direct Mark Electrolytic capacitor or non-polar capacitor with large volume: nominal capacitance, rated voltage and capacitance tolerance. Non polar capacitor with small volume: nominal capacitance, rated voltage and capacitance tolerance. Capacitance unit: μF, nF, pF Eg: 1p2 means 1.2pF 1n ...

Classification and Energy Storage Principle of Supercapacitors

The structure of supercapacitor（also called super capacitor, ultracapacitor, gold capacitor and electric double layer capacitor-EDLC） is similar to that of lithium-ion battery, which is assembled in order of positive pole / diaphragm / negative pole. The positive and negative electrodes are all formed by coating the active material on the collecting fluid, drying and compacting. The isolation memb...

Advantages and Disadvantages of Silver Mica Capacitors

Silver mica capacitor is made of tin foil and mica sheet as medium, laminated and die-cast in bakelite powder, its shape is mostly square. It uses natural mica as the medium between capacitor poles, so its voltage withstanding performance is quite good. Electrode plates made of metal foil or silver sprayed on mica sheets After laminating the plates with mica layer by layer, they are then die-cast ...
