GUS-QS8A-03-7322-CB Description

The GUS-QS8A-03-7322-CB from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. Encased in a 16-pin QSOP package with gull wing terminations, this device offers a 73.2KΩ resistance per element with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. Its isolated (ISOL) circuit design allows independent resistor functionality, making it ideal for precision signal conditioning and voltage division. With a 0.75W total power rating (0.1W per resistor) and a 100V maximum voltage rating, it balances performance and reliability in compact designs.
