IRC Advanced Film Division

IRC’s TaNSil

QSOP resistor networks are the perfect solution for high volume applications that demand a

small wiring board footprint. The .025” 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 QSOP 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 QSOP resistor networks.
