GUS-QS8A-03-8251-DB Description

The GUS-QS8A-03-8251-DB from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. With a resistance value of 8.25KΩ and a tight tolerance of 0.5%, this component ensures reliable performance in precision circuits. Encased in a 16-pin QSOP package, it features gull-wing terminations for secure PCB mounting. The device operates over a wide temperature range of -70°C to +125°C, making it suitable for industrial and automotive-adjacent environments. Its low TCR of ±25ppm/°C minimizes resistance drift under thermal stress, while the isolated (ISOL) circuit design allows flexible configuration in complex layouts.
