Ceramic disc capacitors are extensively utilized in general electronic circuits due to their cost-effectiveness and ease of soldering. The capacitance of these capacitors is determined by the area of the ceramic disk or dielectric, as well as the spacing between the silver electrodes.
Electrolytic Capacitor Electrolytic capacitors are capacitors that exist in two forms: non-polar and polar. The anode of these capacitors typically comprises metal foil, such as aluminum or tantalum, with an oxide film, often aluminum oxide or tantalum pentoxide, serving as the dielectric and adhering closely to the anode.
