GUS-QS8A-02-1241-GB Description

The GUS-QS8A-02-1241-GB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 1.24KΩ resistance value per resistor with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a compact 16-pin QSOP (QSOP-16) package, it offers a 0.75W (3/4W) total power rating and 0.1W (1/10W) per resistor, making it suitable for high-density PCB designs. The gull-wing termination and surface-mount (SMD) compatibility facilitate automated assembly processes.

GUS-QS8A-02-1241-GB Features

• Precision Thin Film Technology: Delivers superior accuracy and stability (±50ppm/°C) compared to thick-film alternatives.
• High Power Handling: 0.75W total power rating (0.1W per resistor) in a compact 4.9mm x 6.02mm x 1.47mm footprint.
• Wide Operating Range: Rated for -55°C to +125°C, with derated power up to 125°C.
• Isolated Design (ISOL): Each resistor operates independently, ideal for signal isolation or multi-channel circuits.
• Robust Construction: 100V maximum voltage rating and QSOP package with ±0.1mm dimensional tolerances for reliable PCB mounting.
• Non-Automotive (PPAP No): Optimized for industrial, telecom, and instrumentation applications.
