GUS-QS8A-03-1051-GA Description

The GUS-QS8A-03-1051-GA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 1.05KΩ resistance value per resistor with a tight 2% tolerance and an ultra-stable ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range of -70°C to +125°C. Housed in a 16-pin QSOP (QSOP-16) package, it offers a compact 4.9mm × 6.02mm footprint with a low 1.47mm profile, making it ideal for space-constrained PCB designs. The gull-wing termination ensures secure surface-mount (SMD) assembly, while the 0.64mm terminal pitch facilitates high-density layouts. Rated for 0.1W (1/10W) per resistor and 0.75W (3/4W) total power dissipation, it supports robust operation in demanding environments.

GUS-QS8A-03-1051-GA Features

• Precision Thin Film Technology: Delivers superior stability, low noise, and high accuracy.
• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk.
• Wide Operating Range: Derated power up to 125°C, suitable for industrial and automotive-adjacent applications.
• High Voltage Tolerance: Supports up to 100V, enhancing reliability in power-sensitive circuits.
• Compact QSOP Package: Optimized for high-density PCBs with a 1.63mm seated height.
• Non-Automotive (PPAP No): Ideal for industrial, medical, and telecom systems where PPAP compliance isn’t required.
