GUS-QS8B-03-2002-D Description

The GUS-QS8B-03-2002-D is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount applications. This 16-pin QSOP package integrates 15 resistors, each with a 20K Ohm resistance and an ultra-tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide operating temperature range of 70°C to 125°C, making it suitable for environments with thermal fluctuations. The network supports a maximum voltage rating of 100V and offers a total power rating of 0.75W (3/4W), distributed as 0.05W (1/20W) per resistor. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting in space-constrained designs.

GUS-QS8B-03-2002-D Features

• Precision Thin Film Technology: Delivers low noise and high stability for critical analog circuits.
• Compact QSOP Package: Measures 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm length/height, ±0.2mm depth).
• High Power Density: 0.75W total power in a miniaturized footprint, ideal for power-sensitive designs.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power handling.
• Automotive-Grade Alternatives: While not PPAP or automotive-qualified, its performance parallels higher-tier industrial components.
• Non-RoHS Compliant: Suitable for legacy or exempted applications requiring leaded soldering.

GUS-QS8B-03-2002-D Applications

This resistor network excels in:

• Precision Instrumentation: Medical devices, test equipment, and sensor interfaces requiring low TCR and tight tolerances.
• Telecommunications: Signal processing and impedance matching in RF modules.
• Industrial Controls: PLCs, motor drives, and power supplies where thermal stability is critical.
• Legacy Electronics: Military/aerospace systems exempt from RoHS compliance.

Conclusion of GUS-QS8B-03-2002-D

The GUS-QS8B-03-2002-D combines high accuracy, robust power handling, and compact packaging, distinguishing it from generic resistor arrays. Its thin-film construction and gull-wing termination ensure reliability in precision circuits, while the QSOP form factor optimizes board space. Though not RoHS-compliant, it remains a top choice for non-consumer applications demanding long-term stability under thermal stress. Engineers will value its balance of performance and density in analog and mixed-signal designs.
