C8717E

Description

C8717E is a pure Ag conductor that yields a smooth, dense film on alumina. The material was designed for thick print applications and a fired film thickness can be achieved up to 200 μm.C8717E is recommended for power hybrid applications where high current is a requirement. C8717E is an excellent choice for high conductivity applications that require very thick conductor tracks.
