GQ8A011271BBT Description

The GQ8A011271BBT 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 1.27KΩ resistance value per element with an ultra-tight 0.1% tolerance and a low ±100ppm/°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 0.75W (3/4W) total power dissipation and 0.1W per resistor, making it suitable for high-density PCB designs. The gull-wing termination and surface-mount (SMD) configuration facilitate automated assembly, while its 100V maximum voltage rating enhances reliability in industrial and instrumentation circuits.
