GUS-QS8A-03-1780-FF Description

The GUS-QS8A-03-1780-FF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP surface-mount device features 8 isolated resistors, each with a 178Ω resistance value and a tight 1% tolerance. With a ±25ppm/°C temperature coefficient, it ensures stable performance across a wide operating temperature range of 70°C to 125°C. The network delivers a total power rating of 0.75W (3/4W) and 0.1W (1/10W) per resistor, making it suitable for demanding circuits. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting, while the compact 4.9mm x 6.02mm x 1.47mm footprint optimizes board space.

GUS-QS8A-03-1780-FF Features

• Precision Thin Film Technology: Ensures low noise, high stability, and excellent TCR performance.
• Isolated Resistor Configuration (ISOL): Each of the 8 resistors operates independently, ideal for signal isolation.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) at 125°C maximum operating temperature.
• Robust Construction: QSOP package with gull-wing leads for mechanical durability and solderability.
• Wide Voltage Rating: Supports up to 100V, suitable for industrial and instrumentation applications.
• Non-Automotive Grade: Optimized for commercial and industrial use (PPAP not required).
