GQ8A0159R0CT Description

The GQ8A0159R0CT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation circuit applications. This 8-resistor array features a 59Ω resistance value per element with an ultra-tight ±0.25% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it offers 0.1W (1/10W) power rating per resistor and a total power dissipation of 0.75W (3/4W), making it suitable for high-density PCB designs. The gull-wing termination and 0.64mm terminal pitch facilitate reliable surface-mount assembly, while its 100V maximum voltage rating enhances durability in isolation applications.
