GUS-QS0B-03-7871-JA Description

The GUS-QS0B-03-7871-JA 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 7.87KΩ resistance value and a tight ±5% tolerance. It operates over a wide temperature range of 70°C to 125°C (derated) and delivers a total power rating of 1W (0.05W per resistor). With a ±25ppm/°C temperature coefficient, it ensures stable performance in thermally dynamic environments. The gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting, while its compact 8.66mm × 6.02mm × 1.47mm footprint suits space-constrained designs.
