Abstract
A cermet resistor employs film terminations of sub-micron thickness. The terminations contain particles of SiO.sub.2 or MnO.sub.2 that may be conveniently made by mixing such particles in a metal resinate paste, screening the paste on a glazed or unglazed substrate and firing. A glass containing resistor paste is screened in overlapping relationship with the fired terminations and is itself fired. The particle additives ameliorate cracking of the terminations at resistor firing and enhance the termination to substrate bond.
