GUS-QS8B-02-6812-D Description

The GUS-QS8B-02-6812-D 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 68.1kΩ resistance value 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 0.75W (3/4W) 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-QS8B-02-6812-D Features

• Precision Thin Film Technology: Delivers low noise and high stability for critical analog circuits.
• Compact QSOP Package: Measures 4.9mm (L) x 6.02mm (D) x 1.47mm (H) with tight tolerances (±0.1mm length/height, ±0.2mm depth), ideal for space-constrained designs.
• High Power Density: 0.75W total dissipation in a miniature footprint outperforms similar arrays in power handling.
• Automation-Friendly: Gull-wing leads and 0.64mm terminal pitch simplify pick-and-place assembly.
• Extended Temperature Range: Operates reliably from -70°C to +125°C, even at derated power.
• Non-Automotive/Non-PPAP: Optimized for industrial, medical, and instrumentation applications where PPAP compliance isn’t required.
