Tantalum Capacitor Technology : Options for high-temperature and harsh-environment applications

Traditionally, hermetically sealed, wet axial tantalum capacitors, which incorporate a nonsolid electrolyte that promotes self-healing and long lifetimes, have been used for both high-bulk capacitance (up to 5,600 nF) and high-voltage applications (up to 125 Vdc) suited to industrial applications. In recent years, this technology has been developed even further to meet the 200°C operational requirements of harsher environment industrial applications.
