GUS-QS0B-02-1781-DA Description

The GUS-QS0B-02-1781-DA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP surface-mount device integrates 19 resistors with a 1.78KΩ resistance value, offering a tight ±0.5% tolerance and a low ±50ppm/°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 ensures secure PCB mounting, while the compact 8.66mm × 6.02mm × 1.47mm footprint suits space-constrained designs.

GUS-QS0B-02-1781-DA Features

• Precision Performance: Thin-film technology delivers stable resistance values with minimal drift (±50ppm/°C) and 0.5% tolerance for critical circuits.
• Robust Construction: QSOP package with a rectangular shape and ±0.1mm height tolerance ensures mechanical reliability in harsh environments.
• High Power Handling: 1W total power rating (1/20W per resistor) supports energy-efficient designs.
• Automation-Friendly: Gull-wing leads and 0.64mm terminal pitch simplify automated assembly processes.
• Non-Automotive/Non-PPAP: Ideal for industrial and commercial applications where PPAP compliance is not required.
