GQ8A032211CT Description

The GQ8A032211CT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor array features a 2.21KΩ resistance value per resistor with an ultra-tight 0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a 16-pin QSOP ceramic package, it offers superior thermal stability and durability in harsh environments. The isolated (ISOL) circuit design allows independent resistor operation, making it ideal for precision voltage division or current sensing. With a 0.75W total power rating (0.1W per resistor) and a 100V maximum voltage rating, it balances power handling with compact surface-mount (SMD) gull-wing termination.
