GQ8A022740DT Description

The GQ8A022740DT 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 274Ω resistance value per element with an ultra-tight 0.5% tolerance and a low ±50ppm/°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 eliminates crosstalk, making it ideal for precision analog and digital systems. With a 0.75W total power rating (0.1W per resistor) and 100V maximum voltage rating, it balances power handling with compact surface-mount (SMD) gull-wing termination.
