GQ8A034702CBT Description

The GQ8A034702CBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 16-pin QSOP surface-mount device integrates eight 47KΩ resistors with an ultra-tight tolerance of ±0.25% and a low temperature coefficient of ±25ppm/°C, ensuring stable performance across a wide temperature range (70°C to 125°C). Encased in a robust ceramic package, it offers superior thermal stability and durability, with a 0.75W (3/4W) total power rating (0.1W per resistor). Its 100V maximum voltage rating and isolated (ISOL) circuit design make it ideal for precision analog circuits.
