GQ8A011200JCT Description

The GQ8A011200JCT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 8-resistor network features a 120Ω resistance per element with a 5% tolerance and a ±100ppm/°C temperature coefficient, ensuring consistent performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it offers 0.75W (3/4W) total power dissipation and 0.1W (1/10W) per resistor, making it suitable for compact, high-density PCB designs. The gull-wing termination and surface-mount (SMD) configuration facilitate easy assembly, while the 100V maximum voltage rating enhances durability in demanding circuits.

GQ8A011200JCT Features
