GQ8A031273DBT Description

The GQ8A031273DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 16-pin QSOP package integrates 8 isolated 127KΩ resistors with a tight 0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The ceramic case and gull-wing termination provide robust mechanical and thermal stability, making it suitable for surface-mount (SMD) applications. With a 0.75W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is engineered for reliability in precision circuits.
