GUS-QS8A-03-1273-FA Description

The GUS-QS8A-03-1273-FA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 127K Ohm resistance value with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Packaged in a 16-pin QSOP with gull-wing SMD termination, it offers a compact footprint (4.9mm x 6.02mm x 1.47mm) ideal for space-constrained designs. With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, it balances power handling with precision.

GUS-QS8A-03-1273-FA Features

• High Precision: Thin-film technology delivers 1% tolerance and ±25ppm/°C TCR for reliable signal conditioning.
• Robust Construction: QSOP package with gull-wing leads ensures mechanical stability and ease of soldering.
• Isolated Design: Circuit designator "ISOL" indicates independent resistors, reducing crosstalk in critical circuits.
• Wide Operating Range: Rated for -55°C to +125°C, suitable for industrial and automotive (non-AECQ) environments.
• Power Efficiency: 0.1W per resistor (0.75W total) enables use in power-sensitive analog/digital systems.
• Compact Dimensions: 4.9mm length, 6.02mm depth, and 1.47mm height with tight tolerances (±0.1mm) for high-density PCBs.
