GQ8A028250DAT Description

The GQ8A028250DAT 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 offers 825Ω resistance per element with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The 0.75W (3/4W) total power rating and 100V maximum voltage rating make it suitable for high-reliability circuits. Its gull-wing termination and surface-mount design facilitate automated assembly, while the ceramic case enhances thermal and mechanical robustness.
