IRC's TaNFilm
®
ceramic Precision Ball Grid Array offers precision tolerances in a ceramic BGA package.
In addition, the TaNFilm
®
CHC Series provides all the unique qualities of our other TaNFilm
®
package
configurations.
Precise state-of-the-art laser trimming provides close tolerances and tight ratios. The TaNFilm
®
process
enables IRC to manufacture custom circuit configurations and multiple resistance values without
sacrificing the tightest tolerance and tracking characteristics of precision networks. The Tantalum Nitride
resistor material is self-passivating for environmental protection surpassing military requirements and
guaranteeing exceptional ratio stability.
For applications requiring a high degree of reliability, stability, accuracy and low noise, plus the advantages
of new resistor configurations, specify the IRC Precision Ceramic Ball Grid Arrays.
