GUS-QS8A-03-4422-GB Description

The GUS-QS8A-03-4422-GB 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 44.2KΩ resistance value and a tight 2% tolerance. With a ±25ppm/°C temperature coefficient, it ensures stable performance across a wide operating range of -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 compact dimensions (4.9mm x 6.02mm x 1.47mm) enable efficient PCB integration in space-constrained designs.

GUS-QS8A-03-4422-GB Features

• High Precision: Thin-film technology ensures low TCR (±25ppm/°C) and 2% tolerance for reliable signal conditioning.
• Robust Construction: QSOP package with 100V maximum voltage rating and 125°C max operating temperature for harsh environments.
• Isolated Resistors: 8 independent resistors (ISOL circuit designator) prevent crosstalk in multi-channel systems.
• Optimized Power Handling: 0.75W total dissipation (0.1W per resistor) balances performance and thermal management.
• Space-Efficient: 0.64mm terminal pitch and 1.47mm profile suit high-density PCBs.
• Non-Automotive: Compliant with EAR99 (ECCN) but not PPAP or RoHS certified.
