GUS-QS8A-03-8452-CB Description

The GUS-QS8A-03-8452-CB from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. Encased in a compact 16-pin QSOP package with gull wing terminations, it features an 84.5KΩ resistance per element with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide -70°C to +125°C operating range. The isolated (ISOL) circuit design allows independent resistor operation, while the 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for high-reliability circuits. Its thin film technology delivers superior accuracy and low noise compared to thick-film alternatives.

GUS-QS8A-03-8452-CB Features

• Precision Performance: ±0.25% tolerance and ±25ppm/°C TCR for critical analog/digital signal conditioning.
• Robust Construction: QSOP package (4.9mm x 6.02mm x 1.47mm) with 0.64mm pitch, ideal for space-constrained PCBs.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) at 125°C derated power, outperforming standard networks.
• Isolated Design: Independent resistors (ISOL) enable flexible circuit configurations without crosstalk.
• Thin Film Advantage: Low parasitic effects and stable performance in precision voltage dividers, feedback loops, or sensor interfaces.
