GQ8B0191R0FDT Description

The GQ8B0191R0FDT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 15 resistors, each with a 91Ω resistance value and a tight 1% tolerance, ensuring consistent performance in precision circuits. The ceramic case and gull-wing termination provide robust mechanical stability and reliable solderability. Rated for 0.75W (3/4W) total power dissipation and 0.05W (1/20W) per resistor, it operates across a wide temperature range of -70°C to +125°C, with a ±100ppm/°C temperature coefficient for minimal drift. Its 100V maximum voltage rating and thin-film technology make it suitable for high-reliability environments.
