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.
