GUS-QS8B-02-3742-D Description

The GUS-QS8B-02-3742-D from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 15 resistors with a 37.4K Ohm resistance value, offering a tight 0.5% tolerance and a low ±50ppm/°C temperature coefficient. With a 0.75W (3/4W) total power rating and 0.05W (1/20W) per resistor, it operates reliably across a 70°C to 125°C derated power range, peaking at 125°C maximum operating temperature. The gull-wing termination and 0.64mm terminal pitch ensure secure PCB mounting, while its compact 4.9mm x 6.02mm x 1.47mm footprint suits space-constrained designs.

GUS-QS8B-02-3742-D Features

• Precision Thin Film Technology: Delivers stable performance with ±50ppm/°C TCR and 0.5% tolerance for critical analog/digital circuits.
• Robust Power Handling: 0.75W total rating (0.05W per resistor) supports higher current applications than standard networks.
• High Voltage Tolerance: 100V maximum voltage rating ensures reliability in industrial and instrumentation systems.
• Compact QSOP Package: 16-pin gull-wing SMD design with 1.63mm seated height optimizes board space.
• Wide Temperature Range: Operates from 70°C to 125°C (derated) with full performance at 125°C.
• Non-Automotive/Non-PPAP: Ideal for commercial and industrial use where PPAP compliance is not required.
