MIL-DTL-3965 Capacitor, Fixed Electrolytic \(Nonsolid Electrolyte\), TantalumThis specification covers the general requirements for tantalum, electrolytic \(nonsolid electrolyte\), fixed capacitors \(polarized and nonpolarized\), hermetically and nonhermetically sealed \(see 1.2.1.7\) in metal cases; style CL67 and all tubular-foil styles are insulated \(see 6.1\). This specification also covers removable counting brackets for use with the CL55-series capacitors.
