GUS-QS8B-00-2742-JF Description

The GUS-QS8B-00-2742-JF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package integrates 15 resistors, each with a 27.4KΩ resistance value and a tight 5% tolerance, ensuring consistent performance in demanding circuits. With a 0.75W (3/4W) total power rating (0.05W per resistor) and an operating temperature range of 70°C to 125°C, this network is engineered for reliability in thermally challenging environments. Its ±250ppm/°C temperature coefficient guarantees stable resistance values across temperature fluctuations, while the 100V maximum voltage rating makes it suitable for low-to-medium voltage applications.

GUS-QS8B-00-2742-JF Features

• Compact & Robust Design: 4.9mm x 6.02mm x 1.47mm dimensions with ±0.1mm length/height tolerances ensure precise PCB integration.
• High-Density Configuration: 15 resistors in a QSOP gull-wing SMD package optimize space in densely populated boards.
• Thin-Film Technology: Delivers superior accuracy, low noise, and stability compared to thick-film alternatives.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power handling.
• Automotive & Industrial Suitability: Though not PPAP or automotive-rated, its 125°C max operating temperature suits industrial controls, power supplies, and instrumentation.
• Non-RoHS Compliant: Ideal for legacy or niche applications where RoHS exemptions apply.

GUS-QS8B-00-2742-JF Applications

This resistor network excels in:

• Signal Conditioning Circuits: Precision voltage dividers, feedback networks, and analog signal processing.
