GUS-QS8A-03-4122-CB Description

The GUS-QS8A-03-4122-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 component offers an isolated (ISOL) circuit configuration, ensuring individual resistor performance without shared connections. With a 41.2KΩ resistance value and an ultra-tight ±0.25% tolerance, it delivers exceptional accuracy for precision analog and digital circuits. The thin film technology ensures low noise and stable performance, while its ±25ppm/°C temperature coefficient minimizes resistance drift across a wide operating range of -70°C to +125°C. Rated for 100V maximum voltage and 0.75W total power dissipation, it combines reliability with compact dimensions (4.9mm × 6.02mm × 1.47mm), making it ideal for space-constrained designs.
