Capacitor with glass metal conductive layer

摘要

A glass-metal powder mixture, preferably including silver, is used in place of the usual epoxy resin-silver outer layer of a tantalum capacitor. This reduces temperature sensitivity during soldering and avoids penetration of silver into the graphite and manganese dioxide layers of the capacitor. Thinner layers of graphite and MnO2 can be used and reduced carbonization provides improved conductivity. A small solder bead can also be used instead of dipping into a solder bath.
