GUS-QS8A-03-2490-FB Description

The GUS-QS8A-03-2490-FB from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Encased in a 16-pin QSOP package with gull wing termination, this 249 Ohm, 1% tolerance device offers excellent stability with a low ±25ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power and 0.1W per resistor, it operates reliably across a 70°C to 125°C derated power range, with a maximum operating temperature of 125°C. Its isolated (ISOL) circuit design ensures independent resistor functionality, while the 100V maximum voltage rating and thin film technology deliver superior accuracy and durability in demanding environments.
