Precision Ceramic Ball Grid Arrays CHC-Precision Series • Ratio tolerances to ±0.05% • Absolute tolerances to ±0.1% • RoHS compliant terminations available • Superior TaNFilm® resistors on ceramic substrate • Same footprint as the industry standard SOIC-N package 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.
