GUS-QS8A-03-5111-CB Description

The GUS-QS8A-03-5111-CB from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. Housed in a compact 16-pin QSOP package with gull wing terminations, it offers a 5.11 kΩ resistance per resistor with an exceptional ±0.25% tolerance and a low ±25 ppm/°C temperature coefficient. The device operates over a wide temperature range of -70°C to +125°C, with a derated power range of 70°C to 125°C, ensuring stability in harsh environments. Its 0.75W (3/4W) total power rating and 0.1W (1/10W) per resistor make it suitable for power-sensitive designs, while the 100V maximum voltage rating adds versatility.

GUS-QS8A-03-5111-CB Features
