GUS-QS0B-03-4752-FA Description

The GUS-QS0B-03-4752-FA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP-packaged device integrates 19 resistors with a 47.5KΩ resistance value, offering 1% tolerance and a low ±25ppm/°C temperature coefficient. Rated for 1W total power dissipation (0.05W per resistor), it operates reliably across a wide temperature range of -70°C to +125°C, with a maximum voltage rating of 100V. Its gull-wing termination and 0.64mm terminal pitch ensure compatibility with automated PCB assembly processes. The compact dimensions (8.66mm x 6.02mm x 1.47mm) make it ideal for space-constrained designs.

GUS-QS0B-03-4752-FA Features

• Precision Thin Film Technology: Delivers stable performance with minimal drift over temperature and time.
• High-Density Integration: 19 resistors in a QSOP-20 package reduce board space versus discrete components.
• Robust Power Handling: 1W total rating (derated to 70°C–125°C) suits power-sensitive applications.
• Low TCR (±25ppm/°C): Ensures consistent resistance in varying thermal environments.
• Automation-Friendly: Gull-wing leads and 0.64mm pitch enable high-speed SMT placement.
• Non-Automotive/Non-PPAP: Optimized for industrial, telecom, and instrumentation use.
