Precision Ceramic
Ball Grid Arrays
CHC-Precision Series
• Ratio tolerances to ±±0±ꢀ5
• Absolute tolerances to ±±0.5
• 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 package0 In
addition, the TaNFilm® CHC Series provides all the unique qualities of our other TaNFilm® package
configurations0
Precise state-of-the-art laser trimming provides close tolerances and tight ratios0 The TaNFilm® process
enables IRC to manufacture custom circuit configurations and multiple resistance values without sacrificing the
tightest tolerance and tracking characteristics of precision networks0 The Tantalum Nitride resistor material is
self-passivating for environmental protection surpassing military requirements and guaranteeing exceptional
ratio stability0
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 Arrays0
