GQ8A036340CAT Description

The GQ8A036340CAT 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 a 634Ω resistance value with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of 70°C to 125°C. Its isolated (ISOL) circuit design minimizes 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. The gull-wing termination and surface-mount (SMD) form factor facilitate automated assembly.
