Wire Bondable Voltage Divider Network 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 miniature physical dimensions. Excellent performance in harsh, humid environments is a trademark of IRC’s selfpassivating TaNSil® resistor film. For applications requiring high performance voltage dividers in a miniature, wire bondable package, specify IRC DSOT wire bondable die.
