GUS-QS0B-03-3741-CB Description

The GUS-QS0B-03-3741-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 3.74KΩ resistance value per resistor with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. 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 ideal for precision analog and digital circuits.

GUS-QS0B-03-3741-CB Features

• High Precision: Thin-film technology delivers ±0.25% tolerance and ±25ppm/°C TCR for critical signal conditioning.
• Robust Construction: QSOP package (8.66mm × 6.02mm × 1.47mm) with ±0.1mm height/length tolerances ensures reliable SMT assembly.
• Wide Temperature Range: Operates from -70°C to +125°C with derated power up to 125°C.
• Low-Power Design: 0.05W per resistor (1W total) balances performance and thermal management.
• Automotive-Grade Alternatives: While not PPAP or automotive-qualified, its 100V rating and stability suit industrial and instrumentation use.
