GUS-QS8B-03-3570-D Description

The GUS-QS8B-03-3570-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 357 Ω resistance value and an ultra-tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±25 ppm/°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 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.

GUS-QS8B-03-3570-D Features

• Precision Thin Film Technology: Offers 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), ideal for space-constrained designs.
• High Power Density: 0.75W total dissipation (15 resistors) in a miniature footprint outperforms discrete alternatives.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power, suited for industrial and automotive (non-AECQ) applications.
• Low TCR (±25 ppm/°C): Minimizes resistance drift under thermal stress, critical for precision instrumentation.
• Non-Automotive (PPAP No): Optimized for commercial/industrial use where AECQ compliance isn’t required.
