• Ultra-stable tantalum nitride resistors

DSOT Series Issue January 2009 Sheet 1 of 3

IRC’s TaNSil® voltage divider networks are ideally suited for low cost

divider applications that demand precision performance in a wire

bondable package.

The tantalum nitride ﬁlm system on silicon provides precision tolerance, exceptional TCR tracking and minia-

ture physical dimensions. Excellent performance in harsh, humid environments is a trademark of IRC’s self-

passivating TaNSil® resistor ﬁlm.

For applications requiring high performance voltage dividers in a miniature, wire bondable package, specify

IRC DSOT wire bondable die.
