DSOT Series
•
Tight TCR tracking
•
Extremely small footprint
•
Precision ratio tolerances to ±0.05%
•
Ultra-stable tantalum nitride resistors
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.
