GUS-QS8A-03-73R2-GG Description

The GUS-QS8A-03-73R2-GG from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP surface-mount device features 8 isolated resistors, each with a 73.2 Ω resistance and a tight 2% tolerance. With a ±25 ppm/°C temperature coefficient, it ensures stable performance across a wide temperature range (70°C to 125°C). The network delivers a total power rating of 0.75W (3/4W) and 0.1W per resistor, making it suitable for demanding circuits. Its gull-wing termination and 0.64 mm pitch enable reliable PCB mounting, while the compact 4.9 mm × 6.02 mm × 1.47 mm footprint saves board space.

GUS-QS8A-03-73R2-GG Features

• Precision Thin Film Technology: Offers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistor Design (ISOL): Each of the 8 resistors operates independently, ideal for multi-channel isolation.
• Robust Power Handling: Supports 0.75W total dissipation with derated performance up to 125°C.
• High Voltage Tolerance: 100V maximum rating ensures reliability in industrial environments.
• Compact QSOP Package: Space-efficient 16-pin gull-wing SMD design suits high-density layouts.
• Wide Temperature Range: Operates reliably from -55°C to +125°C (derated above 70°C).
