GUS-QS8A-03-1580-FD Description

The GUS-QS8A-03-1580-FD from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 158Ω resistance value per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Packaged in a 16-pin QSOP (Quarter Small Outline Package) with gull-wing SMD termination, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) ideal for space-constrained PCB designs. The 0.1W power rating per resistor and 0.75W total power rating make it suitable for moderate power dissipation requirements.

GUS-QS8A-03-1580-FD Features

• Precision Thin Film Technology: Delivers high accuracy (±1%) and low TCR (±25ppm/°C) for stable performance in varying environments.
• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk in sensitive circuits.
• Robust Construction: QSOP package with gull-wing leads ensures reliable surface-mount assembly and mechanical durability.
• Wide Voltage Rating: Supports up to 100V, making it versatile for analog and digital systems.
• Extended Temperature Range: Operates reliably from -70°C to +125°C, suitable for industrial and automotive-adjacent applications (though not PPAP/AEC-Q200 qualified).
• Compact & Lightweight: Ideal for high-density PCBs in portable and miniaturized electronics.
