GUS-QS8A-02-1403-BB Description

The GUS-QS8A-02-1403-BB from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. Encased in a compact 16-pin QSOP package with gull wing terminations, it offers a 140K Ohm resistance per element with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient. The isolated (ISOL) circuit design ensures independent resistor performance, while the 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for high-reliability circuits. Its thin film technology delivers superior stability and low noise, critical for precision analog and digital systems.

GUS-QS8A-02-1403-BB Features

• Precision Performance: 0.1% tolerance and ±50ppm/°C TCR ensure minimal drift in harsh environments.
• Robust Construction: QSOP package (4.9mm x 6.02mm x 1.47mm) with 0.64mm terminal pitch optimizes PCB space.
• High Power Handling: 0.75W total power (0.1W per resistor) derated from 70°C to 125°C, with a 125°C max operating temperature.
• Isolated Design: Independent resistors (ISOL) prevent cross-talk, ideal for multi-channel applications.
• Thin Film Technology: Delivers low noise, high stability, and long-term reliability vs. thick film alternatives.
