The tantalum nitride film system on silicon provides precision
tolerance, exceptional TCR tracking and miniature physical
dimensions. Excellent performance is harsh, humid
environments is a trademark of self-passivating, TaNSil
®
resistor film.
For applications requiring high performance resistor dividiers
in a surface mount packge, specify SOT series resistors
TaNSil
®
SOT resistor networks are ideally suited for low cost
divider applications that demand precision performance in a
small printed wiring board footprint. Available in a SOT23
package, it is fully compatible with the latest surface mount
assembly techniques. Compliant gull wing leads relieve
thermal expansion and contraction stresses created by
soldering and temperature excursions.
