GQ0A0290R9GDT Description

The GQ0A0290R9GDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low thermal drift. This 20-pin QSOP (Quarter Small Outline Package) device features 10 isolated resistors, each with a 90.9Ω resistance, 2% tolerance, and a ±50ppm/°C temperature coefficient. Encased in a ceramic package, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C and a derated power range of 70°C to 125°C. The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. Its gull-wing termination ensures reliable surface-mount (SMD) assembly, while the compact dimensions (8.66mm x 6.02mm x 1.47mm) save board space.
