GUS-QS8B-01-2551-G Description

The GUS-QS8B-01-2551-G from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors, each with a 2.55KΩ resistance value and a tight 2% tolerance, ensuring consistent performance. The network operates over a wide temperature range of 70°C to 125°C (derated) and can withstand up to 125°C at full load, making it suitable for environments with thermal stress. With a 0.75W (3/4W) total power rating and 0.05W (1/20W) per resistor, it balances power handling and compactness. The ±100ppm/°C temperature coefficient ensures stability across temperature variations, while the 100V maximum voltage rating provides robust protection against overvoltage conditions.

GUS-QS8B-01-2551-G Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog and digital circuits.
• Compact QSOP Package: Measures 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with ±0.1mm height tolerance, ideal for space-constrained PCB designs.
• Gull Wing Termination: Ensures reliable surface-mount (SMD) soldering with a 0.64mm terminal pitch for high-density layouts.
• Robust Power Handling: 0.75W total dissipation (15 resistors) with derating up to 125°C, outperforming standard networks in thermal management.
• Non-Automotive, Non-PPAP: Optimized for industrial, telecom, and instrumentation applications where PPAP compliance is not required.
• Non-RoHS: Suitable for legacy or exempted applications requiring leaded components.
