GUS-QS8A-03-5491-FF Description

The GUS-QS8A-03-5491-FF 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 5.49KΩ resistor network offers 1% tolerance and a ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it balances compactness (4.9mm length, 6.02mm depth, 1.47mm height) with robust performance. Its 100V maximum voltage rating and isolated (ISOL) circuit design make it ideal for noise-sensitive environments. Packaged in a tube, it is optimized for surface-mount (SMD) assembly in automated processes.
