GQ8A0156R2CT Description

The GQ8A0156R2CT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation (ISOL) circuit applications. This 8-resistor array features a 56.2Ω resistance value per element with an ultra-tight ±0.25% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it offers a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for high-reliability designs. The gull-wing termination and surface-mount (SMD) configuration facilitate automated assembly processes.
