GQ8A022800BAT Description

The GQ8A022800BAT from TT Electronics/IRC is a high-precision 8-resistor thin-film network designed for demanding isolation and signal conditioning applications. Housed in a 16-pin QSOP ceramic package, it features 280Ω resistance per element with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The isolated (ISOL) circuit design eliminates crosstalk, while the 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for high-reliability environments. Its gull-wing termination and surface-mount (SMD) form factor (4.9mm × 6.02mm × 1.47mm) enable compact PCB integration.
