SOIC Series
IRC’s TaNSil® SOIC resistor networks are the perfect solution for high volume applications that demand a small
wiring board footprint. The .050" lead spacing provides higher lead density, increased component count,
lower resistor cost, and high reliability.
The tantalum nitride film system on silicon provides precision tolerance, exceptional TCR tracking, low cost
and miniature package. Excellent performance in harsh, humid environments is a trademark of IRC’s self-pas-
sivating TaNSil® resistor film.
The SOIC series is ideally suited for the latest surface mount assembly techniques and each lead can be
100% visually inspected. The compliant gull wing leads relieve thermal expansion and contraction stresses
created by soldering and temperature excursions.
For applications requiring high performance resistor networks in a low cost, surface mount package, specify
IRC SOIC resistor networks.
