GUS-QS8A-03-1243-DB Description

The GUS-QS8A-03-1243-DB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 8 isolated resistors, each with a 124K Ohm resistance value and an ultra-tight 0.5% tolerance. The device operates over a wide temperature range of 70°C to 125°C (derated) and delivers a total power rating of 0.75W (3/4W), with 0.1W (1/10W) per resistor. Its ±25ppm/°C temperature coefficient ensures stability in fluctuating thermal environments, while the 100V maximum voltage rating and gull-wing termination enhance reliability in compact PCB layouts.

GUS-QS8A-03-1243-DB Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±0.5%) for sensitive analog circuits.
• Robust Construction: QSOP package (4.9mm x 6.02mm x 1.47mm) with a 0.64mm terminal pitch optimizes space efficiency.
• Isolated Resistors (ISOL): Independent circuits reduce crosstalk, ideal for multi-channel systems.
• High-Temperature Resilience: Rated for 125°C maximum operating temperature, suitable for industrial environments.
• Surface-Mount Design: Gull-wing leads facilitate automated assembly and secure soldering.
• Non-Automotive/Non-PPAP: Tailored for commercial and industrial use (non-compliant with automotive standards).
