Electrolytic capacitor Electrolytic capacitor An electrolytic capacitor (abbreviated e-cap) is a polarized capacitor whose anode or positive plate is made of a metal that forms an insulating oxide layer through anodization. This oxide layer acts as the dielectric of the capacitor. A solid, liquid, or gel electrolyte covers the surface of this oxide layer, serving as the (cathode) or negative plate of the capacitor. Due to their very thin dielectric oxide layer and enlarged anode surface, electrolytic capacitors have a much higher capacitance-voltage (CV) product per unit volume compared to ceramic capacitors or film capacitors, and so can have large capacitance values.
SAL electrolytic capacitor loads have a much higher reliability with respect to tantalum electrolytic capacitors. In addition, the dielectric aluminum oxide in combination with the electrolyte manganese dioxide has a relatively high voltage resistance against wrong polarity. SAL electrolytic capacitors are used for filtering, smoothing coupling and decoupling applications in industrial, medical and automotive equipment. The axial style of SAL capacitors has military and high professional applications up to 200 °C. Compared to non-solid electrolytic capacitors, SAL capacitors Compared to polymer electrolytic capacitors, SAL capacitors The standardization for all electrical, electronic components and related technologies follows the rules given by the International Electrotechnical
