Title:
SOLID ELECTROLYTIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2023/234342
Kind Code:
A1
Abstract:
A solid electrolytic capacitor (1) according to the present disclosure comprises: a capacitor element (2); a lead terminal (4) and a lead terminal (5), which are electrically connected to the capacitor element (2); and an outer case (3) which seals a part of the lead terminal (4), a part of the lead terminal (5) and the capacitor element (2). The outer case (3) comprises a resin part that contains a resin. In the resin part, if a glass transition temperature Tg of the resin is the temperature at which the loss elastic modulus stops increasing and takes a downward turn as determined by nanoscale dynamic viscoelasticity measurement that utilizes a nanoindentation method, the glass transition temperature Tg is 140°C or less; and within the temperature range from the glass transition temperature Tg to 260°C, the hardness of the resin part as determined by the nanoindentation method is 0.08 GPa or less.
