GUS-QS0B-03-3740-CB Description

The GUS-QS0B-03-3740-CB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 374Ω resistance value per resistor with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Housed in a compact 20-pin QSOP package with gull-wing terminations, it offers a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for high-density PCB designs. The 6.02mm × 8.66mm footprint and 1.47mm profile enable space-efficient integration, while its non-automotive and non-PPAP compliance aligns with industrial and commercial use cases.
