4700 Series
The IRC 4700 Series is the ultimate combination of precision
performance, reliability, and long term stability in a low profi le,
TaNFilm® SIP package. Rugged welded lead construction combined with the inherent passivation
characteristics of tantalum nitride insure superior ongoing performance over the installed life of the part.
