GUB Series
IRC’s TaNFilm®, Small Outline Integrated Circuit resistor networks are ideally suited for surface mounting. The
0.05 inch lead spacing provides higher lead density, increased component count, lower installed resistor cost,
and better reliability. They are ideally suited for the latest surface mount assembly techniques, and each lead
can be 100% visually inspected. The compliant leads relieve thermal expansion and contraction stressed
created by soldering and temperature excursions.
The tantalum nitride film system provides precision tolerance, exceptional TCR tracking, and low noise.
TaNFilm® provides stability, high reliability, and long life characteristics. Testing has demonstrated performance
exceeding MIL-PRF-83401 characteristics H.
Custom circuits and special testing available.
