GUS-QS0B-03-3091-JG Description

The GUS-QS0B-03-3091-JG from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP surface-mount device integrates 19 resistors, each with a 3.09KΩ resistance value and a tight ±5% tolerance. The network operates over a wide temperature range of 70°C to 125°C, with a derated power rating of 0.05W (1/20) per resistor and a total power rating of 1W. Its ±25ppm/°C temperature coefficient ensures stable performance in thermally dynamic environments. The gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting, while the compact 8.66mm × 6.02mm × 1.47mm footprint suits space-constrained designs.
