GQ0A028661JAT Description

The GQ0A028661JAT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 20-pin QSOP (Quarter Small Outline Package) device integrates 10 isolated resistors, each rated at 8.66KΩ with a 5% tolerance and a ±50ppm/°C temperature coefficient. Encased in a ceramic package, it offers excellent 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 secure surface-mount (SMD) assembly, while the QSOP package (8.66mm x 6.02mm x 1.47mm) optimizes board space efficiency.
