GUS-QS8B-01-3572-B Description

The GUS-QS8B-01-3572-B from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 15 resistors, each with a 35.7KΩ resistance value and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±100ppm/°C temperature coefficient, it delivers stable performance across a wide operating temperature range of 70°C to 125°C. 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-01-3572-B 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 height/length, ±0.2mm depth).
• High Power Density: 0.75W total dissipation in a miniature footprint, ideal for densely populated boards.
• Wide Temperature Range: Operates reliably from -55°C to +125°C (derated power up to 125°C).
• Automotive-Grade Alternatives: While this model is not PPAP or automotive-qualified, similar variants are available for harsh environments.
• Non-RoHS Compliant: Suitable for legacy or exempted applications requiring leaded components.

GUS-QS8B-01-3572-B Applications

• Precision Instrumentation: Used in medical devices, test equipment, and data acquisition systems where tolerance and TCR are critical.
• Industrial Control Systems: Ideal for PLCs, motor drives, and feedback networks due to its high voltage and power handling.
• Telecommunications: Employed in RF modules and base station circuitry for impedance matching and filtering.
• Aerospace & Defense: Suitable for avionics and radar systems requiring stable performance under thermal stress.
• Legacy Electronics Repair: Non-RoHS compliance makes it a fit for servicing older equipment.

Conclusion of GUS-QS8B-01-3572-B

The GUS-QS8B-01-3572-B excels in applications demanding high precision, compactness, and thermal resilience. Its thin-film construction, tight tolerances, and robust power rating distinguish it from generic resistor arrays, making it a preferred choice for engineers designing high-reliability analog and mixed-signal circuits. While not suited for automotive use, its performance in industrial, telecom, and aerospace sectors underscores its versatility. For designs requiring RoHS compliance or PPAP certification, alternative models within TT Electronics/IRC’s portfolio should be evaluated.
