GQ0A031911JBT Description

The GQ0A031911JBT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP package integrates 10 isolated resistors, each with a 1.91KΩ resistance and a 5% tolerance, delivering a total power rating of 1W (0.1W per resistor). The device operates over a wide temperature range of 70°C to 125°C with a low temperature coefficient of ±25ppm/°C, ensuring stability in demanding environments. Its ceramic case and gull-wing termination provide robust mechanical and electrical performance, while the surface-mount design (6.02mm x 8.66mm x 1.47mm) suits compact PCB layouts. Rated for 100V maximum voltage, it is ideal for isolation circuits (marked ISOL) in analog and mixed-signal systems.
