GUS-QS8B-02-1910-J Description

The GUS-QS8B-02-1910-J from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP surface-mount device integrates 15 resistors, each with a 191 Ω resistance value and a tight ±5% tolerance. The network operates over a wide temperature range of 70°C to 125°C (derated) with a maximum operating temperature of 125°C, ensuring reliability in demanding environments. With a ±50ppm/°C temperature coefficient, it delivers stable performance under thermal stress. The 0.75W (3/4W) total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for high-density circuits requiring consistent power dissipation.
