GQ8A019311CT Description

The GQ8A019311CT from TT Electronics/IRC is a high-precision, surface-mount thin-film resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor network features a 9.31KΩ resistance value per resistor with an ultra-tight tolerance of ±0.25% and a low temperature coefficient of ±100ppm/°C, ensuring stable performance across a wide operating 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 channels, while the gull-wing termination facilitates reliable PCB mounting. With a maximum voltage rating of 100V and a total power rating of 0.75W (0.1W per resistor), this network balances precision and robustness.
