Type CSR21 (MIL-C-39003/09)
Solid Tantalum Capacitors
125 ºC, Hermetically Sealed, Axial Leaded, Solid Tantalum Capaci-
Type CSR21 (MIL-C-39003/09) military grade, ax-
ial leaded, solid tantalum capacitors are hermetically
sealed for rugged environmental applications. They
have a very low ESR and are great for high frequency
applications.
