GUS-QS8A-03-1433-FF Description

The GUS-QS8A-03-1433-FF from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 8-resistor isolated network features a 143K Ohm resistance value with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a 16-pin QSOP package with gull-wing terminations, it offers a compact footprint (4.9mm x 6.02mm x 1.47mm) and robust 0.75W (3/4W) total power rating, making it ideal for space-constrained, high-reliability circuits.

GUS-QS8A-03-1433-FF Features

• Precision Thin Film Technology: Delivers superior accuracy (±1%) and low TCR (±25ppm/°C) for stable signal conditioning.
• High Power Handling: 0.1W per resistor (0.75W total) at 125°C maximum temperature, outperforming standard networks in derated environments.
• Isolated Circuit Design (ISOL): Each resistor is electrically isolated, enabling flexible circuit configurations.
• Robust Construction: QSOP package with gull-wing leads ensures reliable surface-mount attachment and mechanical durability.
• Wide Voltage Rating: Supports up to 100V, suitable for industrial and telecom applications.
• Non-Automotive/Non-PPAP: Optimized for commercial and industrial use, though not PPAP-qualified.
