GUS-QS8A-03-4021-GA Description

The GUS-QS8A-03-4021-GA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 4.02KΩ resistance value with a tight 2% tolerance and an ultra-stable ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). Housed in a compact 16-pin QSOP package, it offers a 0.75W (3/4W) total power rating and 0.1W per resistor, making it ideal for space-constrained designs requiring high power dissipation. The gull-wing termination and 0.64mm terminal pitch facilitate easy surface-mount assembly, while its 100V maximum voltage rating enhances durability in demanding circuits.

GUS-QS8A-03-4021-GA Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• High Power Handling: 0.75W total rating (0.1W per resistor) outperforms standard networks in power density.
• Isolated Design (ISOL): Each resistor operates independently, reducing crosstalk in multi-channel systems.
• Robust Construction: QSOP package (4.9mm x 6.02mm x 1.47mm) with gull-wing leads for mechanical resilience.
• Wide Temp Range: Operates reliably from 70°C to 125°C with derated power, suited for industrial environments.
• Low TCR (±25ppm/°C): Minimizes resistance drift under thermal stress, critical for precision instrumentation.

GUS-QS8A-03-4021-GA Applications

• Signal Conditioning: Ideal for op-amp feedback networks, DAC/ADC interfaces, and voltage dividers.
