Abstract:
A solid electrolytic capacitor comprising:a capacitor element including: a positive electrode lead of a valve metal having the general configuration of a sheet, a positive electrode body fabricated by forming and sintering a desired shape of a valve material powder arranged such that said positive electrode lead is embedded therein with one end exposed, a dielectric oxide film formed on a surface of said positive electrode body, an electrolyte layer formed on a surface of said dielectric oxide film, a negative electrode layer formed on a surface of said electrolyte layer; a positive electrode terminal connected directly without intervening conductive elements to said positive electrode lead to have an electrical path length that attenuates an equivalent serial resistance (ECR) thereof; a negative electrode terminal connected to said negative electrode layer to have an electrical path length that attenuates an equivalent serial resistance (ECR) thereof; and an insulating housing resin encapsulating said capacitor element, wherein said positive electrode terminal and said negative electrode terminal are exposed at least partially to an outside of said housing resin and are disposed on an outer surface of the housing resin.
