GUS-QS8A-03-3011-JB Description

The GUS-QS8A-03-3011-JB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor array features a 3.01KΩ resistance value per resistor with a tight ±5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Packaged in a 16-pin QSOP with gull-wing SMD termination, it offers a compact footprint (4.9mm x 6.02mm x 1.47mm) ideal for space-constrained designs. The network supports a maximum voltage rating of 100V and delivers a total power rating of 0.75W (0.1W per resistor), making it suitable for demanding circuits requiring isolation (denoted by "ISOL" circuit designator).
