GUS-QS8A-02-3090-JF Description

The GUS-QS8A-02-3090-JF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 8-resistor isolated network features a 309Ω resistance value per resistor with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of -70°C to +125°C. Housed in a compact 16-pin QSOP (QSOP-16) package, it offers 0.75W (3/4W) total power dissipation and 0.1W (1/10W) per resistor, making it suitable for space-constrained, high-density PCB designs. The gull-wing termination ensures reliable surface-mount (SMD) assembly, while the 100V maximum voltage rating enhances its versatility in various circuit protection and signal conditioning roles.

GUS-QS8A-02-3090-JF Features

• Precision Thin Film Technology: Delivers low noise, high stability, and tight tolerance (±5%) for critical analog and digital circuits.
• Isolated Resistor Network (ISOL): Each resistor operates independently, reducing crosstalk in multi-channel applications.
• Robust Thermal Performance: Operates at derated power up to 125°C, ideal for industrial and automotive-adjacent environments (though not PPAP/Automotive certified).
