GQ8A022550CT Description

The GQ8A022550CT from TT Electronics/IRC is a high-precision 8-resistor thin-film network designed for isolation (ISOL) applications. Housed in a 16-pin QSOP ceramic package, it offers a 255Ω resistance per element with an exceptional ±0.25% tolerance and a ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range (70°C to 125°C). The device features gull-wing SMD terminations for reliable surface-mount assembly and delivers a total power rating of 0.75W (0.1W per resistor), making it suitable for demanding analog and digital circuits. Its 100V maximum voltage rating and ceramic case enhance durability in harsh environments.
