C-250J

Description

C-250J is a low resistance carbon paste designed for screen printing membrane switches, printed flexible circuits and other printed electronic applications. The combination carbon and graphite blend gives excellent resistance against repeat wear from SMT components while also maintaining high conductivity.

Key Features
