GUS-QS8A-03-9312-GF Description

The GUS-QS8A-03-9312-GF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount technology. This 16-pin QSOP package features 8 isolated resistors, each with a 93.1K Ohm resistance value and a tight 2% tolerance, ensuring reliable signal conditioning and voltage division. With a ±25ppm/°C temperature coefficient, it delivers exceptional stability across a wide operating range of -70°C to +125°C, making it suitable for demanding environments. The 0.75W (3/4W) total power rating and 100V maximum voltage rating further enhance its robustness in circuit designs requiring isolation and durability.

GUS-QS8A-03-9312-GF Features

• Thin-Film Technology: Offers superior accuracy, low noise, and long-term stability compared to thick-film alternatives.
• High Power Handling: 0.1W per resistor (0.75W total) enables use in power-sensitive applications without derating concerns.
• Isolated Circuit Design (ISOL): Each resistor operates independently, ideal for multi-channel systems.
• Compact QSOP Package: 4.9mm (L) x 6.02mm (D) x 1.47mm (H) footprint saves board space while supporting 0.64mm pitch gull-wing leads for secure SMD mounting.
• Extended Temperature Range: Reliable performance from -70°C to +125°C, suited for industrial and automotive-grade applications (though not PPAP/Automotive certified).
