GUS-QS0B-02-7151-DD Description

The GUS-QS0B-02-7151-DD is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a 7.15KΩ resistance and a tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±50ppm/°C temperature coefficient, it maintains stable performance across a wide operating range of -70°C to +125°C, making it suitable for environments with thermal fluctuations. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust handling of moderate power loads. Its gull-wing termination ensures reliable solder joints in automated PCB assembly processes.

GUS-QS0B-02-7151-DD Features

• Precision Thin Film Technology: Delivers low noise and high stability for critical analog circuits.
• Compact QSOP Package: Measures 8.66mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height/length), ideal for space-constrained designs.
• High Power Density: 1W total dissipation (distributed across 19 resistors) outperforms similar networks in power handling.
• Automation-Friendly: Gull-wing leads and 0.64mm pitch enable seamless surface-mount placement.
• Extended Temperature Range: Operates reliably up to 125°C, suited for industrial and automotive-adjacent applications (though not PPAP/Automotive certified).
