GUS-QS8A-01-1742-GF Description

The GUS-QS8A-01-1742-GF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP surface-mount device features eight isolated 17.4KΩ resistors with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it is engineered for reliability in demanding circuits. The gull-wing termination and QSOP package (4.9mm x 6.02mm x 1.47mm) facilitate compact PCB layouts while maintaining robust mechanical integrity.

GUS-QS8A-01-1742-GF Features

• Precision Thin Film Technology: Delivers superior accuracy and stability compared to thick-film alternatives.
• Isolated Resistors (ISOL): Each of the 8 resistors is electrically isolated, ideal for independent signal paths.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) supports power-sensitive designs.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, suitable for industrial and automotive environments (though not PPAP/automotive-certified).
• Compact QSOP Package: 16-pin gull-wing SMD with a 0.64mm terminal pitch maximizes space efficiency.
• Non-RoHS Compliant: Suitable for legacy or exempted applications requiring leaded components.
