GUS-QS8A-03-1961-BA Description

The GUS-QS8A-03-1961-BA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerance and stable performance. This 8-resistor network features a 1.96KΩ resistance value per resistor with an ultra-tight 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Packaged in a 16-pin QSOP with gull-wing SMD termination, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) while delivering 0.1W (1/10W) power dissipation per resistor and 0.75W (3/4W) total power handling. Rated for 125°C maximum operating temperature, it supports derated operation up to 70–125°C, making it suitable for high-reliability environments.
