Electrolytic capacitor anodic oxide film growth technology

🌻An electrolytic capacitor differs significantly from other types in that its dielectric is an extremely thin anodic oxide film electrolytically generated on the valve metal, the thickness of which is closely related to the applied voltage. The oxide film is the heart part of the electrolytic capacitor, and its quality is related to the product performance, [...]

Nominal capacitance and allowable tolerance of electrolytic capacitor

The basic unit of a electrolytic capacitor is Farah (F), but this unit is too large and is rarely used in field marking. Other unit relationships are as follows: 1F=1000mF 1mF=1000μF 1μF=1000nF 1nF=1000pF The deviation between the actual capacitance of the electrolytic capacitor and the nominal capacitance is called tolerance, and the accuracy is called within [...]

Principle of internal working structure of capacitor

The capacitor utilizes a surface effect with two electrode plates 1: Suppose a piece has a positive charge on it, then the other side will have a corresponding positive charge, so that an electric field is formed between the two plates, and the potential difference of the electric field is the voltage. 2: Assuming that a [...]

Precautions for capacitor use

1. Aluminum electrolytic capacitor is a two-polar structure (see the mark on the capacitor body). Please pay attention to the polarity when installing.Alternating current (ac) or the application of the reverse voltage may cause short circuit or a damaged capacitor circuit polarity may occur in the reverse or not sure, so the dual polarity capacitors is [...]
