GUS-QS8A-03-9312-DB Description

The GUS-QS8A-03-9312-DB 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 termination, this device offers a 93.1 kΩ resistance value per resistor with an ultra-tight ±0.5% tolerance and a low ±25 ppm/°C temperature coefficient, ensuring stability across a wide temperature range (70°C to 125°C). Its isolated (ISOL) circuit design allows independent resistor operation, making it ideal for precision signal conditioning and voltage division. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it balances performance and reliability in compact designs.
