GQ8A011133CT Description

The GQ8A011133CT 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 113K Ohm resistance value with an ultra-tight 0.25% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Housed in a 16-pin QSOP ceramic package, it offers excellent thermal stability and durability, making it suitable for harsh environments. The isolated (ISOL) circuit design ensures minimal crosstalk between resistors, while the gull-wing termination enables reliable surface-mount (SMD) assembly. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network balances precision with robustness.
